Internal medicine practices lose thousands of dollars every month due to claim denials. Common reasons include coding mistakes, missing documentation, and insurance-related issues.

One of the biggest causes of denials is poor eligibility verification. Verifying insurance coverage, co-pays, preventive benefits, and referral requirements before appointments helps reduce avoidable claim rejections and payment delays.

Common Reasons for Internal Medicine Claim Denials
• Incorrect E/M coding
• Missing modifier 25
• Preventive vs diagnostic visit confusion
• CCM documentation errors
• Outdated ICD-10 codes
• Lack of medical necessity documentation
• Missing prior authorization requirements

7 Proven Strategies to Reduce Claim Denials
1. Verify Insurance Before Every Appointment
Check patient eligibility 24–48 hours before visits to confirm:
• Active coverage
• Co-pay responsibility
• Referral requirements
• Covered services
2. Improve E/M Coding Accuracy
Incorrect E/M coding leads to audits and denials.
