However, converting handwritten PDFs to text is still a big challenge. Old methods of digitization are not precise enough in the conversion of handwriting to editable and machine-printed text because they lead to errors and confusion. In the current era of advanced technology, many tools and techniques are very helpful to handle this challenge. The tools to convert handwritten PDFs to text use OCR technology and transform them into editable text within seconds. Such tools make it easier to organize and share your words in that document. To know how to convert scanned files with handwritten text, we will discuss free options that will simplify your conversion of handwritten PDFs. These tools also make digitization and data extraction more manageable. Challenges in Handwriting data extraction There are many challenges in handwriting data extraction due to several reasons. The process of handwriting data extraction includes digitization. It converts handwritten documents into that digital format. This step is easy and straightforward. The real and noteworthy challenges in handwriting data extraction arise when we have to turn these scanned images into editable text. Here we will see some valid challenges in the extraction of data from handwritten scanned images; 1. Irregularities in handwriting styles The primary challenge is the irregularities in handwriting styles. People generally write in many different ways. They use different angles, forms, and sizes of letters. These irregularities make text recognition a complicated process. In this case, machine learning algorithms are very useful to improve accuracy, but sometimes, they also struggle with chaotic or unreadable handwriting. 2.  Transcription The second most important challenge is transcription. It can also be problematic, especially when you are dealing with older documents where liquid ink is faded or scanned image paper has worsened. In these situations, the conversion of scanned PDF images into editable text can produce errors. These errors lead to inappropriate data extraction. 3.  Context The third important challenge is context. It plays a crucial role in precise data extraction. Sometimes, handwriting recognition systems misinterpret numbers or letters. They interpret wrongly, especially when there is high uncertainty or misplaced information. Addressing this challenge needs cutting-edge technology and advanced Machine Learning Algorithms. Such technologies ensure correct transcription and reliable Data extraction. What are the main methods or tools for Automated Handwriting data extraction? For automated handwriting data extraction, there are numerous primary techniques or tools available. However, a few noteworthy and useful ones are as follows: 1.    Optical Character Recognition The most common method for converting handwritten PDFs into editable text is Optical Character Recognition. It works by examining the scanned images of documents and identifying the shapes and patterns of individual characters. Optical Character Recognition tools can help in extracting text from native PDFs. However, its performance decreases when used for extracting handwritten. 2.    Intelligent Character Recognition The second most common method is Intelligent Character Recognition. It is considered for Handwriting recognition text. This Automated Handwriting data extraction method uses machine learning algorithms to understand several styles of handwriting. Intelligent Character Recognition is particularly convenient when you need to convert handwritten PDFs to text. The main reason behind this is that it can; Handle different handwriting styles Produce editable text with greater accuracy Intelligent Character Recognition is far more flexible than in print fonts. 3.    Free Online Tools Many free online tools can help you convert handwritten PDFs to text.

However, extracting, editing, or parsing data from these files can be a lot of work to do. In today’s data-driven world, efficiently extracting information from PDF documents is essential. This article talks about the problems with getting data from PDFs and shows how to extract data from PDFs to Excel online. Whether you need to get text, and tables, or make PDFs searchable, we’ll cover solutions that are fast, accurate, and easy to use. Challenges in PDF Data Extraction: Let’s explore some of the key challenges encountered in PDF data extraction, shedding light on why what may seem like a simple task can often become quite complex. Manual PDF text extraction requires meticulous attention to detail, making it a time-consuming endeavor. A slight error can lead to inefficiencies and potential errors. Human errors are common in manual extraction, potentially impacting the accuracy of the extracted data. Unlike other document formats like DOC, XLS, or CSV, editing PDF data is not straightforward, hindering customization according to specific requirements. Extracting data from tables in PDFs often results in the loss of original formatting, making it challenging to maintain data integrity. How to Extract Data from PDF Files in 2024: Extracting data from PDFs used to be a lot of work when the technology hadn’t advanced back in the days. However, now, with the advent of AI, OCR, and NLP, you don’t have to spend hours on manually extracting the data. All you need is an efficient tool like Algodocs that does the job for you accurately and easily. Let’s look at different PDF data extraction methods in 2024: Do it Manually While not the preferred method in 2024, manual data extraction remains a necessity for startups or beginners who are not ready to invest in good PDF data extraction software or are new to technology. Whether handling school documents, business reports, medical records, or any other file type, manual extraction is still widely utilized, although it is considered a less refined approach. Use Adobe Acrobat For more professional-grade PDF page extraction, Adobe Acrobat is a solid option. Although it’s not free, you can try it out with a 7-day free trial.

Categories Data Extraction PDF Tags ai platform for data extraction algodocs character recognition data extraction from images deep learning export extracted data to excel invoice process machine learning ocr api web-based ai platform for data extraction By Shubhankar Biswas Published October 13, 2025, 12:03 Updated July 29, 2026, 02:32 A PDF Parser is a program or a library that enables end-users and organizations to parse data from native PDF documents. Often, organizations need to parse PDF documents for specific fields such as Account Number, Date, Address, Bill to/from information, or parse tabular data. PDF Parsers are usually needed and used for processing and parsing data from large amounts of documents. On the other hand, when you have a handful of documents you simply go and copy the data you need from PDF documents manually and paste it to Excel or anywhere you need it to be. PDF Parsers enable end-users to get data from hundreds and thousands of PDF documents in real time by saving huge amounts of time and, thus, money. Parsing pdf documents isn’t an easy task. There are various ways native pdf documents are generated and parsing data from such pdf documents requires smart approaches. Parsed data from PDF documents greatly varies depending on the industry, which means the data parsed might also greatly change, which complicates the task. Parsing PDF medical forms, which contain specific fields such as First, Middle, and Last names, Sex, Date of Birth, etc. are very different from PDF purchase orders that contain mainly the items in the tabular form with such columns as Item No, Code, Quantity, Item Price, Amount, etc. Therefore, if PDF Parser produces just a bunch of text from a PDF document it does not make much sense for the end-user. What end-users or organizations require is the structured data parsed from PDF documents. In other words, PDF Parser should extract from PDF documents only the data the end-user needs and in the right structured format. For this, the PDF Parser must be smart and flexible enough to parse PDF documents with various layouts and data types. How to parse PDF documents with various layouts? Algodocs allows you to parse PDF documents of any complexity in their layouts and type of data. With the flexible extracting rules of Algodocs, you can parse data from PDFs with different layouts. It is very easy and quick to set up extractors in Algodocs for your PDF documents. We provide 100% free technical support and are ready to set up extractors for you. While we provide free support for creating extracting rules, you may check our help and support section if you wish to learn how to create extracting rules in Algodocs. Watch the following introductory video to get an idea of how it works in Algodocs. Feel free to start a free subscription right now and parse your pdf documents. You can use Algodocs free forever with 50 pages per month. If you need to process a higher number of pages, then please see our affordable pricing plans.

Convert PDF to JSON – Convert PDF Documents to Structured JSON Objects

Back to Blog Table of contents On this page Convert PDF to JSON – Convert PDF Documents to Structured JSON Objects Home › Blog › PDF › Convert PDF to JSON – Convert PDF Documents to Structured JSON Objects Categories PDF Tags ai platform for data extraction algodocs character recognition data extraction from images deep learning export extracted data to excel invoice process machine learning ocr api web-based ai platform for data extraction By Shubhankar Biswas Published October 13, 2025, 11:59 Updated July 21, 2026, 05:15 Introduction Organizations in various industries widely use PDF documents, since no doubt PDF is a common document format for businesses to transfer data. Purchase orders, Invoices, Agreements, and many more document types are interchanged in PDF formats. On the other hand, JSON is another format that represents data in a structured format, which is widely used in transferring data between web applications. As a result, Working with JSON is much easier than with PDF. Therefore, in this article, we will talk about PDF and JSON formats and how you can convert your PDF documents to JSON format. What is a PDF? PDF (Portable Document Format) was initially developed by Adobe® Systems in 1992 and is standardized as ISO 32000. What makes PDF so popular is it is independent of the application software, hardware, and operating system. Other than text and images PDF files may contain a variety of content such as annotations, form fields, layers, etc. There are many advantages of PDF format such as multi-dimensionality, which we have already mentioned – being able to contain various types of content, text, images, videos, vector graphics, interactive fields, hyperlinks, and buttons. Moreover, PDF documents are easily created and viewed on different devices.  Security in PDF was one of the primary concerns of Adobe® Systems. Therefore, PDFs have different access levels to protect the content and the whole document, such as passwords, digital signatures, and watermarks. However, some of the downsides of a PDF are the complexity of editing and especially extracting data from it. Moreover, PDFs are not generated in the same way, so different PDF files can be created in various ways, which complicates the task of extracting data from PDF documents. What is a JSON? JSON (JavaScript Object Notation) is a very popular data format, which appeared in the early 2000s. JSON is a language-independent data format and is used to transfer data between software applications, particularly web applications, usually between server and client.  Most of the API integrations are realized using JSON format for data transfer since it is very easy to work with JSON. Consider a JSON object called person, which contains the following information:{   “name”: “John”,   “surname”: “Doe”,   “age”: 25} Accessing fields of a JSON object is as simple as using the name of the object and the field name you want to access by separating them with a dot as follows: To access a person’s name we use person.name, which will give us “John” as a result. Similarly, we do for surname and age fields: person.surname, person.age Note how easy it is to access any field of a JSON object, which is definitely not compared to accessing specific information in the PDF document. How does JSON differ from PDF? Although PDF and JSON are both widely spread and used, there is a huge difference between PDF and JSON. The difference between them is simply in the purpose of their usage. PDF is mainly used for exchanging information between humans, since it contains text, graphics, illustrations such as images and videos, etc. On the other hand, JSON is mainly used between computer programs and different applications for communicating and exchanging data between each other. It is not an easy task for a human to read information from a JSON file, especially if it is a compressed one, but it is a perfect way to access information from JSON for a software application. The opposite goes for the PDF. Therefore, PDF and JSON become important, useful, and helpful only when they are used in the right place and for the right purpose. How to Convert PDF to JSON? Often, organizations need to transfer data to other programs for further processing. This data is often stored in PDF documents since businesses often speak to each other in a “PDF language”. However, extracting information from PDF documents can be challenging.  The simplest solution is that you can always copy and paste text from a PDF and send it to where it belongs. However, this simple approach has many problems, since first of all this will work only with native PDF files (not scans) for which you can even use some free PDF Parsers. Another problem even if your PDF documents are all native, it is not easy to copy the entire table from a PDF by maintaining its format, especially if the table spans over multiple pages, for example, 100 or 1000 pages. Additionally, often organizations need to extract specific data from PDFs, for example not the entire table, but instead specific rows or columns based on some conditions. Last, but not least, it is not worth spending your valuable time on menial data entry! Convert PDF documents to JSON with Algodocs Algodocs offers a perfect solution to extract any type of data from PDF documents and transfer it to other programs in real-time. Algodocs can extract fields and tables of any complexity from native as well as scanned PDF documents. You can convert your PDF documents to JSON in three steps with Algodocs. First, start by creating an extractor in Algodocs. Algodocs has some preprocessing operations that take some time depending on the number of pages your PDF document contains; usually, it is around 15-20 seconds. Then, go to the ‘Extracting Rules’ editor to create your extracting rules for every field you need to extract from your PDF documents. Similarly, if you need to extract tables from your PDF documents you can create extracting rules for tables by selecting ‘Table’ as the data type. After you are done with creating and extracting rules,

Back to Blog Table of contents On this page A Guide on Extracting Tables From Low-Quality Scanned Documents Home › Blog › Image Data Extraction › A Guide on Extracting Tables From Low-Quality Scanned Documents Categories Image Data Extraction Tags ai platform for data extraction algodocs character recognition data extraction from images deep learning export extracted data to excel invoice process machine learning ocr api web-based ai platform for data extraction By Shubhankar Biswas Published October 13, 2025, 11:52 Updated July 22, 2026, 09:54 Many companies deal with thousands of documents every month. Document workflow automation becomes vital for such companies as the number of documents increases. One of the most frequent and at the same time tedious operations when processing documents is reading data from tables, especially when documents are scanned PDFs or images. Automating table extraction from scanned documents and exporting them into Excel or JSON within seconds is a dream for every company dealing with manual data entry. Automating table data extraction from scanned documents and images reduces operational costs and saves a lot of time. In this article, we will talk about table extraction from scanned documents or images with low quality. You, most probably, came across some online tools that can extract tabular data from documents. However, there are a few that really work with low-quality scanned documents or images taken by a mobile device. Optical Character Recognition (OCR) is the technology used for converting scanned images into text. However, standard OCR tools require you to apply certain image processing operations on the images before you can apply OCR on them. Without manual pre-processing, OCR will fail in most cases, and accuracy will be low. Unfortunately, even with pre-processing operations free OCR tools produce poor performance. How to extract tables from scanned PDFs and images with low quality? Algodocs has an advanced AI-powered OCR engine that automatically handles any type of scanned PDF or image with a low quality. Algodocs accepts either colorful scanned images, black and white, or any other settings and extracts data with high accuracy. Algodocs can process scanned images with as low a dpi as 75. If you have scanned PDFs or images with low quality, then Algodocs is the right solution for you. You may start a free subscription right now and test your own scanned documents since we offer a free subscription (forever) with 50 pages per month. If you need to process a higher number of pages, then please see our affordable pricing plans. Please read our article on the basic steps for table extraction from documents here: Extract tables from PDF and scanned documents Algodocs: the best software tool to extract tables from scanned PDFs and images Consider the portions of the scanned documents below and the tables that Algodocs extracted from them. Example #1 Sample scanned image with low-quality (black and white) Extracted table by Algodocs. Example #2 Extracted table by Algodocs As you can see, the accuracy of Algodocs is perfect even with low-quality scans. However, there are cases when scanned images may cause Algodocs to make mistakes concerning small characters such as punctuation or other symbols (points, commas, date separators, etc.). Let’s have a look at the example below with a scanned image and see what Algodocs could extract from it. The extracted table from the above-scanned image is shown below. As you can see, there are numbers that are extracted with wrong decimal separators (indicated in red circles), i.e. a decimal point is mistakenly recognized as a comma. This is due to the dark background that some rows have on the image. With the help of flexible extracting rules of Algodocs, the workaround is quick and simple. Whenever you have low-quality scanned PDFs of images, we always advise you to follow the steps explained below. Step1. Remove all points and commas from the numbers We apply the ‘Search & Replace’ filter in Algodocs by using regular expressions as the search type. We apply this rule to all the columns in the example below, but you can restrict this rule to a specific column when needed. In order to find all dots or commas we use .|, as the search term and we leave empty the second field (replace by this), since we simply want to remove them. Step 2. Convert all numbers to their previous format Since we removed all points and commas from numbers, they actually increased, i.e. multiplied by 100 we can say (2,378.63 became 237863). Therefore, since we know that our numbers had 2 decimal places, we can divide all numbers by 100 to get the original numbers. The ‘Arithmetic Operation’ filter helps us implement exactly this. We divide numbers by 100 in the last column as shown in the example below. You may apply this filter to other columns too. That’s it. We got numbers in their original form with 100% accuracy! The same approach can be applied to other symbols when you have documents with a low quality. Please, contact us if you need any assistance.

The Ultimate FAQ: Mastering AI Data Extraction for Efficient Document Processing

/

Back to Blog Table of contents On this page The Ultimate FAQ: Mastering AI Data Extraction for Efficient Document Processing Home › Blog › Data Extraction › The Ultimate FAQ: Mastering AI Data Extraction for Efficient Document Processing Categories Data Extraction Tags data extraction invoice process loan forms machine learning ocr api By Shubhankar Biswas Published October 12, 2025, 20:25 Updated July 20, 2026, 04:17 As technologies advance in this vast world, information is abundant around us. Data is everywhere: from invoices, bank statements, HR forms, sales orders, contracts, and social media to customer feedback. That brings the question, how can we handle this flood of information around us? This is where data extraction tools pops in. AI data extraction is like a smart digital assistant rummaging through piles of documents, emails, and images to pick out what you need. It’s like having employees working round the clock, with no strikes and no coffee break arguments. In its simplest form, AI data extraction uses machine learning and natural language processing to ‘think’ in a language just as you and I do. It uses this capability to recognize data like tables and handwritten and then extract information. Subsequently, it converts unstructured data into structured form that is easy to work with. But why is this so important? Data extraction can unravel the hidden riches embedded deep within your data. It is time-saving, error-free, and enables individuals to make the right decisions that may prove beneficial to any business. It identifies patterns, filters data, and transforms complex data structures into easily analyzable formats. How AI Data Extraction Works Data Extraction involves using complex technologies such as Optical Character Recognition (OCR), Natural Language Processing (NLP), and Computer Vision. OCR is the system’s eyes that read documents and images to input text. NLP understands text meaning and context, while Computer Vision interprets visual elements like table borders, brand names, warranties, signatures, etc. The process typically starts with data preprocessing, cleaning, and preparing the raw data for extraction. Then, AI-based models, such as Algodocs trained on vast amounts of data, swing into action. They identify patterns and extract relevant/required entities like names, dates, amounts, tables, marks, signatures, etc. Next, Algodocs allows users to export the extracted data directly into their software or structured formats like spreadsheets, XML, or JSON. It’s like teaching a computer to read, understand, and extract wanted/essential info, just like you would with a book or an article. AI data extraction tools like Algodocs handle massive data volumes in seconds or minutes instead of hours or days. Types of Data That Can Be Extracted with AI AI data extraction isn’t limited to just plain text on a page. It’s like a versatile detective, capable of uncovering clues hidden within various data types. First, there is textual data extraction. AI extracts pertinent textual data like names, addresses, and products from PDFs, screenshots, emails, and social media posts. It’s as if you have a secretary who summarizes the important parts of a large pile of documents. Then, numerical data extraction, such as table extraction, is performed. AI extracts prices, quantities, and dates from invoices and financial statements, even handling complex multipage tables. This includes everything from logos and warranty details to signatures, making it a valuable tool for finance, healthcare, manufacturing, etc. Lastly, AI data extraction can address the Wild West or relatively free-for-all environment of semi-structured and unstructured data. It uncovers unknown heroes in your data, whether stored in paperwork or digital formats.

However, a significant portion of this data resides within unstructured documents, such as contracts, invoices, forms, emails, and more. Manually processing data from these documents is time-consuming, error-prone, and costly for any business. Intelligent Document Processing (IDP) has emerged as a game-changing solution by leveraging the power of artificial intelligence (AI) and machine learning (ML). Document workflows and data extraction from these unstructured documents have become very easy. This comprehensive guide will explore the landscape of IDP platforms, their benefits, how they can be applied across various industries, key considerations for choosing an IDP solution, emerging trends, and how Algodocs can empower your business. What is Intelligent Document Processing (IDP)? A Deep Dive The IDP (Intelligent Document Processing) market is expected to reach $46.59 billion USD by the end of 2035, according to a report. As businesses heavily rely on, extraction, sorting, and managing data. These types of operations require a robust and reliable tool to that can provide useful insights about business metrics. That’s why the need for intelligent document processing tools is rising day by day. So, what is intelligent document processing? IDP is a sophisticated technology that automates the extraction, classification, and processing of data from various document types, regardless of format or structure. It achieves this by combining several core technologies: Optical Character Recognition (OCR): OCR converts images of text into machine-readable text. Modern OCR, often referred to as Intelligent Character Recognition (ICR), goes beyond basic character recognition by using deep learning models like Convolutional Neural Networks (CNNs) and Recurrent Neural Networks (RNNs). This allows it to handle complex layouts, handwritten text, low-quality images, multiple languages, and specialized fonts used in industries like healthcare (medical prescriptions) and law (legal documents). Accuracy is often measured using metrics like character error rate (CER) and word error rate (WER), with advanced systems achieving very low error rates. Natural Language Processing (NLP): NLP analyzes the extracted text to understand its meaning and context. It employs techniques like tokenization (breaking text into individual words or phrases), stemming and lemmatization (reducing words to their root form), Named Entity Recognition (NER) (identifying specific entities like names, dates, and locations), Part-of-Speech (POS) tagging (identifying the grammatical role of each word), sentiment analysis (determining the emotional tone of the text), topic modelling (discovering underlying topics within a collection of documents), text summarization (creating concise summaries of longer texts), relationship extraction (identifying relationships between entities), and semantic analysis (understanding the meaning of words and phrases in context). Machine Learning (ML): ML is the engine that drives IDP’s adaptability and continuous improvement. Supervised learning involves training the system on labelled data to recognize specific document types and extract relevant fields. Unsupervised learning helps discover patterns and structures in unlabelled data for improved classification and clustering. Reinforcement learning allows the system to learn through feedback and iterative improvement. Training data quality and quantity are crucial for model accuracy. Techniques like cross-validation and hyperparameter tuning are used to optimize model performance. Active learning allows the system to request human input for ambiguous cases, further improving its accuracy over time. Computer Vision: Computer vision enables IDP to “see” and interpret visual elements within documents. Techniques like image classification (categorizing images), object detection (identifying specific objects within images), image segmentation (dividing an image into multiple segments), table and form extraction (accurately extracting data from structured tables and forms), barcode and QR code recognition (automating data capture from barcodes and QR codes), signature verification (authenticating signatures), and logo detection (identifying company logos) are used. Robotic Process Automation (RPA): RPA acts as the orchestrator for IDP workflows, automating downstream processes based on the extracted data. It integrates IDP with other enterprise systems like CRM, ERP, and ECM, automating data validation, routing documents to appropriate departments, and triggering subsequent actions. IDP Workflow: A Detailed Breakdown: Document Ingestion: Documents are ingested through various channels: scanning, uploading files, APIs, email attachments, and more. Pre-processing: Images are optimized for OCR through techniques like noise reduction, skew correction, and image enhancement. OCR and Text Extraction: OCR extracts text from the document. NLP and Data Understanding: NLP analyzes the extracted text. Data Extraction and Validation: Relevant data is extracted and validated against predefined rules or databases. Human-in-the-Loop (HITL): Human reviewers handle exceptions and complex cases where the system has low confidence. Data Output and Integration: Extracted data is delivered in structured formats (CSV, JSON, XML) or directly integrated into business applications. The Benefits of IDP: Quantifiable Impacts Efficiency Gains: IDP can dramatically reduce document processing time, often by up to 90%. For example, processing hundreds of invoices that previously took several days can be completed in just a few minutes or hours. This increased throughput allows businesses to handle higher volumes of documents without increasing staffing. Cost Reduction: By eliminating manual data entry and reducing errors, IDP can lower operational costs by up to 70%. Reduced rework, fewer errors requiring correction, and optimized resource utilization contribute to significant cost savings. Accuracy Improvement: IDP achieves data extraction accuracy rates of 99% or higher, significantly minimizing data entry errors and improving data quality and consistency. This reduces costly downstream errors and improves compliance. Enhanced Security and Compliance: IDP systems offer robust security features like data encryption, access control, and audit trails, ensuring compliance with data privacy regulations like GDPR, HIPAA, and others. Improved Customer Experience: Faster processing times translate to quicker service delivery, leading to improved customer satisfaction. For example, faster loan approvals or insurance claims processing can significantly enhance the customer

Accurate data extraction ensures timely reimbursements, reduces claim denials, and provides insights into cost-effective care delivery. Handwritten Bills Despite the growing adoption of Electronic Health Records (EHRs), handwritten bills persist in many healthcare settings, particularly in smaller practices or during field visits. Many developing Asian countries, as well as developed countries, still rely on handwritten bills. These bills often contain information such as: Patient Information: Basic details like first name, last name, sometimes age or contact information, dates, etc. Treatment Details: Brief descriptions of services provided, often in abbreviated form. Charges: Handwritten amounts for each service or an overall total. Extracting data from handwritten bills presents a unique challenge due to variations in handwriting styles, abbreviations, and the potential for smudges or illegible entries. Advanced OCR coupled with Natural Language Processing (NLP) is essential for accurate data extraction from these documents. Patient Forms Patient forms are the cornerstone of patient intake and data collection. They gather essential information that forms the basis of a patient’s medical record. Sometimes these forms are filled with handwritten data, which presents a challenge for data extraction. Though the majority of patient forms are computer-generated, in many cases, they are handwritten. Common types of patient forms include: Registration Forms: Collect basic demographics, insurance information, and emergency contacts. Medical History Forms: Document past illnesses, surgeries, allergies, medications, and family history. Consent Forms: Obtain patient authorization for treatment, procedures, or release of information. HIPAA Forms: Ensure compliance with the Health Insurance Portability and Accountability Act regarding patient privacy. These forms often contain valuable information such as first name, last name, address, body weight, blood group details, current health issues, and previous diagnoses. They often contain a mix of structured (checkboxes, multiple-choice) and unstructured (free-text) data. Effective data extraction from these forms relies on advanced form recognition and NLP techniques to capture both types of information accurately. Health Insurance Documents Health insurance documents, including Explanation of Benefits (EOBs) and insurance cards, are crucial for understanding a patient’s coverage, verifying eligibility, and processing claims.
