The diagnosis is SNOMED 53726008 which is acute conjunctivitis. The note says bilateral conjunctivitis (started right, spread to left). I tried H10.33 which wasn't found; let me verify the correct ICD-10 for bilateral acute conjunctivitis, likely H10.33 isn't right - acute conjunctivitis bilateral is H10.33?

The most specific code for bilateral unspecified conjunctivitis is H10.33. Let me verify the correct billable code - H10.33 returned not found, so I'll check H10.30 (unspecified conjunctivitis, unspecified eye) vs a bilateral acute option.

Agent reasoning

Diagnosis H10.33 (unspecified acute conjunctivitis, bilateral) is set, but I should reconsider laterality. The note says bilateral redness, started in RIGHT eye and spread to LEFT eye - so bilateral is correct. Now I need to derive the service line.

Agent reasoning

The denial CO-150 says the E/M level isn't supported AND mentions unbilled services. The chart documents a detailed exam of many systems for an acute illness (bilateral conjunctivitis x6 days, painful, treatment failure with OTC drops). This is an acute uncomplicated illness with prescription management consideration - likely a 99213 was too high but 99212 may be too low. Let me check the E/M guidelines for 99213 to confirm what MDM supports before re-deriving the level.

Agent reasoning

The denial says the E/M level isn't supported AND a documented service appears unbilled. The note documents a conjunctivitis exam (1 acute self-limited problem, no data ordered, OTC drops/low risk) - that's straightforward MDM, supporting 99212, not 99213. I already changed the line to 99212. The remaining concern is whether there's an unbilled service; the chart has no orders/labs/drugs, so 99212 alone is correct. Let me run the scrub on the corrected claim before resubmitting.

Agent reasoning

The denial CO-150 says the E/M level isn't supported AND mentions unbilled documented services - I should check the urgent_care coding guidelines because POS 20 may require a UC global case-rate code (S9083) rather than a fee-for-service E/M for this payer.

Agent reasoning

The denial says the E/M level isn't supported AND that documented services appear unbilled. I changed 99213 to 99212, but the denial also hints I should reconcile charges. Before burning a submission, the visit is a brief acute conjunctivitis with limited exam and no data/Rx — 99212 (straightforward, established) is appropriate. The scrub is clean and the coding differs from the prior 99213 attempt, so I'll transmit now.

Agent reasoning

Both 99212 and 99213 were denied with CO-150/M25, and the narrative hints 'one or more documented services appear to be unbilled.' This is a UC visit - the payer may want the urgent care global case-rate HCPCS (S9083) instead of a fee-for-service E/M.

I've tried 99213 and 99212, both denied with CO-150 noting the E/M level isn't supported AND that documented services appear unbilled. The denial hints I'm missing a charge.

Agent reasoning

Both 99213 and 99212 were denied for the E/M level. The denial narrative also says 'one or more documented services appear to be unbilled' - but the charge feed only lists the E/M. The key issue: this is an urgent care POS 20 visit, and the urgent_care guidelines may require a UC global case-rate HCPCS (like S9088) instead of (or in addition to) the E/M. Let me re-read the urgent care guidelines carefully to confirm the correct coding approach.

I've tried 99213 and 99212, both denied with CO-150 noting the E/M level isn't supported AND that documented services appear unbilled. The chart shows a UC-EST visit with note '23833' added by Holzer and only 1 charge captured. The hint strongly suggests this is an urgent-care global case-rate service (S9083), not a fee-for-service E/M. Let me verify S9083 before committing my last submission.

Both 99213 and 99212 E/M codes were denied with CO-150.

Agent reasoning

The denial was for E/M level not supported and unbilled services. The chart shows this is an Urgent Care (UC) visit (POS 20, visit type UC-EST). The urgent care guidelines indicate the global case-rate HCPCS S9083 is the correct billing for urgent care, which I've now set. Let me verify the urgent care guidelines once more to confirm S9083 is the right approach before running the scrub.

I'll transmit now since I have only 1 attempt left and the claim is verified clean.
