Internal Medicine Billing Challenges
Common operational and payer hurdles we help internal medicine practices address:

- Coordinating Medicare Part B rules, secondary Medigap/crossover claims, and Medicare Advantage plans
- Capturing Transitional Care Management (TCM) and Chronic Care Management (CCM) encounters properly
- Preventing medical necessity denials for in-office ECGs, spirometry, and diagnostic labs
Relevant Coding Requirements
Key CPT, ICD-10-CM, HCPCS, and modifier considerations for internal medicine:
- Internal medicine E/M coding based on Medical Decision Making (MDM) and chronic illness exacerbation
