Common Medicare Claim Issues
Medicare claims must meet applicable billing, coding, documentation, and coverage requirements.
When a claim does not meet those requirements, it may be rejected, denied, or require additional action.
Understanding common issues can help billing teams investigate claim problems more effectively.
1. Incorrect or Incomplete Billing Information
Medicare electronic claims go through initial edits to determine whether they meet basic requirements.
Claims containing errors may be rejected and returned for correction.
2. Eligibility Issues
A patient’s Medicare eligibility can affect whether a claim is payable.
Billing teams should review applicable eligibility information when investigating a claim issue.
3. Incorrect Coding
Coding needs to accurately represent the services reported and comply with applicable Medicare requirements.
CMS’s 2024 reporting data for E/M services identified incorrect coding as a major source of improper payments.
4. Insufficient Documentation
Documentation should support the services reported on the claim.
CMS identifies insufficient documentation as one of the major categories associated with Medicare Fee-for-Service improper payments.
5. Coverage and Medical Necessity Issues
Medicare coverage and payment can depend on whether a service meets applicable requirements.
When reviewing a denial, the billing team should examine the specific reason provided by the Medicare contractor rather than assuming the cause.
CMS publishes standardized review reason codes and statements to help providers understand certain Medicare review decisions.
6. Missing Required Information
Claims may require specific information to support processing.
If required information is missing or invalid, the claim may be rejected or require correction.
What Should Practices Do When a Medicare Claim Has an Issue?
A practical process includes:
- Review the claim response.
- Identify the specific reason.
- Check the claim information.
- Review relevant documentation.
- Determine whether a correction is appropriate.
- Resubmit or appeal when applicable.
- Monitor the claim afterward.
Final Thoughts
Medicare billing involves specific requirements, so claim issues should be reviewed based on the actual reason provided by the Medicare contractor or payer.
A consistent review and follow-up process can help billing teams identify issues and determine the appropriate next step.
