Overview
Internal medicine sees the sickest ambulatory patients and does the most cognitive work — which makes accurate E/M level selection and risk-adjustment capture the single biggest revenue lever. Most practices bill a level below what their documentation supports, and most miss HCC codes entirely.
Why these claims get denied
The denial reasons we see most often in internal medicine — and what our pre-billing checks are built to catch.
- E/M level downcoded because MDM elements weren't clearly documented
- Chronic conditions not coded to the specificity payers require
- HCC-relevant diagnoses documented in the note but never coded on the claim
- Multiple chronic conditions managed but only one diagnosis submitted
- Prolonged services performed but not billed
- Annual wellness visit and problem visit conflicts on the same date

What we do for your practice
- E/M audit against current MDM guidelines so levels reflect actual complexity
- HCC and risk-adjustment capture review on every chronic-condition patient
- ICD-10 specificity coaching so diagnoses code to the highest level supported
- Chronic care management and prolonged service revenue capture
- Documentation feedback to providers with specific, actionable notes
- Payer-by-payer E/M audit risk monitoring

Common questions
Why do our E/M levels get downcoded?
Almost always because medical decision-making isn't clearly documented. Under the current guidelines, level selection rests on problems addressed, data reviewed, and risk — and the note has to make all three visible. The complexity is usually there; the documentation isn't.
What is HCC capture and why does it matter?
Hierarchical Condition Categories drive risk-adjusted payment. Chronic conditions documented in the note but never coded on the claim don't count. For practices in value-based arrangements this is often the single largest revenue gap.
What is G2211 and should we be billing it?
It's an add-on for the complexity of ongoing longitudinal care of a single serious or complex condition. Many internal medicine practices qualify routinely and never bill it.
