Top 10 Billing Mistakes Primary Care Practices Make

Primary care practices are the backbone of healthcare in the United States. But when it comes to billing, even small mistakes can have major consequences. A missed insurance detail, incorrect code, or delayed claim can quickly add up to thousands of dollars in lost revenue. According to the AMA, nearly 20% of medical claims are denied or delayed due to avoidable billing errors.

That’s why understanding and avoiding billing mistakes in primary care is essential. In this blog, we’ll explore the 10 most common billing mistakes primary care practices make, the impact they have on revenue, and practical steps to avoid them.

1. Inaccurate Patient Information

The most basic mistake is often the most costly. Something as simple as a misspelled patient name, an outdated insurance card, or an incorrect date of birth can cause an immediate claim rejection.

Common Errors vs. Impact on Billing

Error Type	Impact on Billing
Misspelled patient name	Claim rejection
Wrong date of birth	Insurance mismatch
Outdated insurance info	Denials and payment delay

Best practice: Verify patient demographics and insurance details at every visit. Even if a patient visits regularly, insurance coverage may change year to year.

2. Skipping Insurance Verification

Many primary care practices assume coverage remains the same for returning patients. This is a costly assumption. If coverage has lapsed or the payer no longer covers a service, the claim will be denied.

Solution: Always verify insurance eligibility and benefits before the patient’s visit. A few minutes upfront can save weeks of appeals later.

3. Coding Errors (ICD-10, CPT, HCPCS)

Incorrect coding is one of the leading causes of denials. In primary care, coding errors can include:

Solution: Regular staff training, coding audits, and using updated coding software. MaxRemind offers expert medical coding services to minimize errors.

4. Misuse of Modifiers

Modifiers clarify when procedures or services were performed under special circumstances. Using them incorrectly can lead to payer rejections. For example:

Best practice: Train staff on when and how to apply modifiers correctly.

5. Failing to Collect Copayments

Copayments are often overlooked, especially in busy practices. While one missed copay may seem minor, hundreds of patients over a year can add up to significant lost revenue.

Solution: Educate front-desk staff to collect copays at check-in. Make policies clear to patients in advance.

6. Late or Incomplete Claim Submission

Each payer has strict filing deadlines. Submitting claims late or with incomplete documentation almost guarantees denial.

Example: Medicare generally requires claims within 12 months of the service date. Private insurers often have shorter windows.

Solution: Use automated claim scrubbing and electronic submissions to speed up the process. Read more in AMA’s Claim Submission Guidelines.

7. Not Keeping Up with Payer Policy Changes

Payers regularly update their rules about what services are covered and how they should be billed. Failing to stay updated can result in repeated denials.

Best practice: Assign a staff member or use RCM software to monitor policy changes across all major payers.

8. Poor Documentation Practices

If documentation doesn’t support the service billed, payers may deny or reduce reimbursement. For example, billing for a chronic care management visit without detailed clinical notes can trigger a denial.

9. Ignoring Denial Management

One of the biggest billing mistakes primary care practices make is not following up on denied claims. Many simply resubmit without fixing the issue, or worse, ignore them altogether.

Impact: Each unresolved denial issue causes a loss in revenue.

Solution: Implement a denial tracking system to identify trends and fix recurring issues. MaxRemind specializes in denial management services.

10. Lack of Staff Training & Oversight

Billing rules and coding guidelines change often. Without continuous staff training, mistakes are inevitable.
