If you've ever visited a doctor’s office, hospital, or clinic, chances are your bill went through a medical biller—even if you never saw them. But what exactly does a medical biller do, and why is this role so important in healthcare?

Whether you’re considering a career in medical billing or just curious about how healthcare payments work behind the scenes, this article will walk you through everything you need to know: from responsibilities and required skills to salary expectations and growth opportunities.

Who Is a Medical Biller?

In the simplest terms, a medical biller is the bridge between healthcare providers, insurance companies, and patients. They ensure that medical services provided by doctors, nurses, and specialists are billed accurately and paid promptly.

Think of medical billers as the financial translators of the healthcare system. They take complex medical records and turn them into clear, structured claims that insurance companies can understand and process. Without them, providers wouldn’t get paid, and patients could end up confused (or overcharged!).

What Does a Medical Biller Do?

Now that we know what a medical biller is, let’s dig deeper into their day-to-day responsibilities. While the role can vary depending on the setting (e.g., hospital, private practice, or third-party billing service), here are the core duties most medical billers handle:

1. Reviewing Medical Records and Codes

Medical billers often work alongside medical coders—or sometimes wear both hats. They use codes that represent diagnoses, procedures, and services provided during a patient visit. These codes (ICD-10, CPT, HCPCS) are used to create insurance claims.

💬 Example: If a patient visits a clinic for a flu shot, the biller ensures that the correct procedure code for the vaccination and the appropriate diagnosis code for flu prevention are included in the claim.

2. Creating and Submitting Insurance Claims

After verifying that all codes are accurate, billers prepare the insurance claims and submit them to private insurance companies, Medicare, or Medicaid using electronic billing software.

This process is called claim submission and must comply with strict industry standards to avoid delays or denials.

3. Tracking Claim Status

Once claims are submitted, medical billers track their progress. If a claim is delayed or rejected, it’s the biller’s job to follow up, correct any issues, and resubmit the claim.

💬 This step requires attention to detail, because even a small error—like a misspelled name or incorrect insurance ID—can lead to a denial.

4. Handling Insurance Denials and Appeals

Insurance companies don’t always pay the first time. That’s where denial management comes in. Billers investigate why a claim was denied, make necessary corrections, and submit an appeal if needed.

This is one of the most challenging parts of the job, but also one of the most important to ensure providers get paid correctly.

5. Posting Payments and Adjustments

Once payments are received, billers post them in the practice’s billing system. They also note any adjustments (e.g., contracted rates with insurance providers) and update patient accounts.

6. Billing Patients Directly

If insurance doesn’t cover the full cost of a service, the remaining balance is billed to the patient. Billers generate statements, answer billing questions, and sometimes help set up payment plans.

7. Ensuring HIPAA Compliance

Medical billers handle sensitive patient information, so they must understand and follow HIPAA regulations to protect patient privacy.
