Agent reasoning

The denial says the E/M level isn't supported AND some documented service appears unbilled. This is an urgent care visit (UC-EST, POS 20). The charge feed captured S9083 (urgent care global case rate). For UNITED HEALTHCARE OXFORD, urgent care may require the S9083 global case rate instead of a separate E/M. I've set the service line to S9083 only. Let me run the scrub to confirm the corrected claim is clean before my final submission.

Agent reasoning

I've already tried 99212 and 99213, both denied with CO-150 saying the E/M level isn't supported AND that unbilled services should be reconciled. The chart's charge feed maps to an urgent-care global case rate (S9083 is already on the line). The denial hint says to reconcile captured charges - the visit type is 'UC - EST' at POS 20 (Urgent Care). Let me check the urgent_care guidelines to confirm whether I should bill ONLY the UC global code S9083 instead of a separate E/M.

Agent reasoning

I switched line 1 from the E/M code to S9083 (the urgent-care global case-rate HCPCS), which is the correct billing for a UC global visit and differs from my two prior E/M-level submissions. The scrub is clean and the system is prompting me to transmit. I'll submit now with my last attempt.

Agent reasoning

All 3 submissions are exhausted and every coding attempt denied. An appeal does not grant extra submissions and the claim cannot be corrected into payment, so the only remaining action is to write off the balance and close the case.
