The E/M is currently 99202; with an acute illness (gastroenteritis with N/V/D), this could level higher, but with a single self-limited problem, no data ordered, and no Rx management documented, low-complexity MDM (99202) is defensible. The claim changed since the last scrub, so I should run the scrub now to surface any blocking flags before committing a submission.

Agent reasoning

The chart documents gastroenteritis (SNOMED 25374005) with nausea and diarrhea. K52.9 is 'noninfective gastroenteritis, unspecified' but the PrevMed note describes it as possibly bacterial/viral ('stomach flu'). However the documentation doesn't specify infectious etiology, so K52.9 is acceptable. Let me verify the urgent care policy — at POS 20 urgent care, this payer may require the UC global case-rate code instead of a fee-for-service E/M.

The denial is CO-150/M25: E/M level not supported. This is an urgent care POS 20 visit. The note documents a problem-focused visit for acute gastroenteritis - one self-limited/acute uncomplicated illness, minimal data, low risk. For a NEW patient that supports 99202 (straightforward MDM). But the denial also hints services may be unbilled. Let me verify the CARC remedy before deciding.
