Running a healthcare practice is about more than delivering excellent patient care — it’s also about keeping the financial side of your practice healthy. Yet, many providers unknowingly lose thousands of dollars each year due to avoidable medical billing mistakes. At HealthHaven Advisors, we’ve seen how these errors create cash flow headaches and unnecessary stress. The good news? With the right systems in place, you can avoid them.
Here are five of the most common medical billing mistakes — and what to do instead:
1. Incorrect Patient Information
Something as small as a missing middle initial or an outdated address can cause claims to be denied or delayed. These errors add up over time.
How to avoid it: Implement a double-check process during patient intake and use electronic systems that flag incomplete or mismatched information.
2. Coding Errors
Improper or outdated codes are one of the top reasons claims get rejected. Whether it’s upcoding, undercoding, or using codes that no longer exist, accuracy is critical.
How to avoid it: Stay current with annual CPT and ICD-10 code updates and provide regular training for your billing staff.
3. Missed Filing Deadlines
Insurance payers have strict claim submission windows. If you miss the deadline, reimbursement may be reduced or denied altogether.
How to avoid it: Use billing software that tracks filing timelines and sends alerts before deadlines approach.
4. Lack of Documentation
Claims without proper supporting documentation often face denials or payment delays. Missing physician notes, test results, or authorizations can derail the process.
How to avoid it: Build a standardized documentation checklist for your team and integrate it into your billing workflow.
5. Failure to Follow Up on Denied Claims
Many practices simply write off denied claims — leaving significant revenue on the table. Insurers count on this lack of follow-through.
How to avoid it: Create a system for tracking, appealing, and resubmitting denied claims to recover revenue that might otherwise be lost.
