What is Medical Billing – A Guide for Providers & Medical Billers

In the healthcare industry, medical billing plays an important role in helping doctors and other professionals receive timely payment for services they provide to patients. However, a minor error in medical billing can lead to insurance claim denials, ultimately harming your practice’s revenue. That’s why for you, it’s essential to understand what medical billing is and how it works to ensure full payment for their services. In today’s guide, we will cover what medical billing is, its process, challenges, and best practices to help you reduce denials and maximize revenue.

What is Medical Billing in Healthcare?

Medical billing is the process of submitting insurance claims to payers for fast, accurate reimbursement for rendered services. From solo practitioners to specialists or therapists working in a large hospital or organization, everyone must go through this process for compensation.

Medical billing in healthcare is a whole process that your payments rely on, whether you get paid or not. The process involves claim submissions, accurate coding, prior authorization checks, patient demographic entry, charge entry, and denial management, all of which lead to improved revenue for providers.

Therefore, without a solid understanding of medical billing, you might face ongoing denials that can severely hurt your practice’s or organization’s revenue.

How Medical Billing Works in Healthcare

Medical billing in healthcare has multiple steps. If you follow it correctly, it helps you grow financially, boost cash flow and reduce denials.

Let’s simplify how medical billing works in healthcare for quick reimbursements.

Patient Registration

The first step in medical billing is patient registration at the time of the appointment. It means the provider should collect all necessary documents before delivering services. The essential documents to check include the patients’ personal information (name, date of birth, address, contact number) and insurance information, including which payer they’re enrolled in. After collecting all necessary data, the front-end billing staff enter it into the Practice Management System (PMS) to prevent denials.

Insurance Verification

After gathering all important documents, the front-end staff verify the data, including insurance coverage plans, including co-pays and deductibles, before visiting the patient. Moreover, by confirming coverage plans, they also check whether prior authorization is required for the patient’s services/treatment to ensure smooth billing.

Medical Coding

The most critical part in medical billing is the coding. It means you should translate physicians’ clinical notes into standard CPT, ICD-10, and HCPCS codes, which requires accuracy because even minor errors in medical coding can lead to payment delays.

Charge Entry

Once the medical codes are perfectly assigned, promptly and efficiently create a bill in the billing software by adding service or treatment fees and modifiers (if required), ensuring you earn for each service you deliver.

Claim Scrubbing

In 2026, revenue cycle experts added this step to the medical billing process to ensure error-free claim submission. Claim scrubbing is the initial step and becomes the most important part of back-end billing, through which medical billers double-check claims, verify the accuracy of modifier use, and coding. Although they verify prior authorization, the patient demographics are correct.

Claim Submission

You need to submit claims on time within the specified timeframe, which is approximately 90-120 days, depending on your medical specialty and payer requirements. Hence, ensure claims are submitted on time to avoid delays and denials.

Payer Adjudication

The most critical phase throughout the medical billing process is payer adjudication. In this step, the payer or insurance company, such as Medicare, Medicaid, or another insurer, decides whether to pay for the claims. Hence, they verify and check the medical codes for the rendered services and ensure coverage and benefits.

Payment Posting

Once the insurance company receives the payment, your staff should record and verify the amount to confirm whether you will be paid in full. Follow up for underpayments and denials if they occur to ensure you get every dollar you owe.

Denial Management

If an insurance company denies payment for services, medical billing falls under denial management. In this step, denial management specialists identify the root cause of denials, categorize them and fix errors to resubmit the claims.

Follow-Up & Payment Collection

The last step in the medical billing process is the follow-up of denied or unpaid claims, tracking them until the insurance company release the payments.

Medical Billing Vs Medical Coding – Are They Both the Same?

Healthcare professionals and medical billers often confuse medical billing and coding due to some aspects.

In short, medical billing is the entire process that improves the revenue cycle, while medical coding is only one part – but yes, it’s essential. Without medical coding, facility providers, doctors and hospitals can’t submit claims.

Medical Billing refers to the submission of claims with accurate medical coding, prior-authorization checks, charge entry, eligibility and benefits verification, and denial management, which together improve financial stability and boost cash flow.

Medical Coding refers to translating the physician’s clinical notes of diagnosis, procedures and treatments delivered to patient care into standardized CPT, ICD-10, and HCPCS codes described by the American Medical Association (AMA). If coders assign incorrect codes, claims would be rejected instantly, increasing administrative burden and rework and sometimes resulting in revenue loss.

Challenges Healthcare Professionals Face in Medical Billing

There are not a few challenges that healthcare professionals face in medical billing, but many. Let’s discuss some top medical billing challenges providers face.

Frequent Payer Changes

In the healthcare industry, something changes in medical billing every year, whether it’s payer policies or AMA medical codes. Due to these frequent changes, providers face complications when adapting to payer-specific regulations by medical specialty. Hence, it increases the chances of errors in the billing process, leading to rejections or denials.

Higher Claim Rejections or Denials

Nowadays, many insurance companies use AI in medical billing software to detect minor errors in claims, resulting in higher rejections and denials.

Compliance Issues

The most challenging part is staying compliant with healthcare billing regulations, which change continuously. If you don’t follow it or HIPAA regulations, then you may face cyberattacks, penalties and even fraud. Hence, to protect your and patients’ data, ensure your billing process is fully compliant with HIPAA rules.

In-House Vs Outsource Medical Billing Services – What You Should Choose

In-house billing can cost you thousands of dollars, as you need to train staff, manage their salaries, and may need to invest in billing software to streamline the billing process. Moreover, in-house medical billing increases administrative workload when handling the high volume of patients, making the process error-prone and increasing the chances of denials, leaving the provider stressed.

On the other hand, outsourcing medical billing services to third parties cuts costs on staff training, salary and billing software. Moreover, you gain access to certified medical billers and coders who efficiently handle thousands of claims simultaneously, achieving a clean claim ratio. Whether you’re a solo practitioner, have a small therapy clinic, or have a large nephrology practice, outsourcing front-end and back-end medical billing services can help you achieve a 95% clean claim ratio, which improves the overall revenue cycle.

Best Practices to Improve Medical Billing Process

In the United States, medical billing changes frequently, which causes insurance claim denials or revenue loss. It severely impacts practices and slows the reimbursement process, leaving providers, doctors, or nurse practitioners stressed and tired. To reduce the denial ratio, you should follow billing strategies which improve the revenue cycle process.

Here are some of the best practices which help improve the medical billing process, reduce administrative workload and start practicing without any stress.

Stay Updated With Medical Billing Changes

To improve revenue cycle management, make sure to stay updated with every medical billing change – whether it’s about coding, compliance or insurance company rules. By staying updated, you’ll avoid using outdated or deleted codes, which can help you pass first-time claim acceptance.

Implement AI in Medical Billing

Another effective strategy you can implement to improve medical billing is to use artificial intelligence and technology, especially in 2026. Many medical billing companies, such as eClaim Solution, use AI in medical coding to scan physicians’ clinical notes and suggest accurate CPT, ICD-10, and HCPCS codes, ensuring accuracy, minimizing claim rejections and improving financial workflow.

Adapt Proactive Denial Management Approach

The best practice you could apply is a proactive denial management approach, which means fixing errors before claim submission so denials can’t occur and you receive payments on time.

Although we ensure every submitted claim is processed, if you have any unpaid claims, resubmit them to earn every dollar you deserve.
