The ERA denial is CO-150/M25 on the E/M line, so I need to confirm the payer-defined denial meaning and recommended corrective path before burning the final submission. I expect this to clarify whether the remedy is corrected coding/removal of unsupported E/M or appeal with documentation.

Agent reasoning
The denial specifically says the E/M level is unsupported and that documented services may be unbilled, so before using the final submission attempt I need to reconcile the charge-capture output against the chart activity. I expect this to identify whether the visit should be billed as a different encounter/urgent-care charge or whether another documented charge is missing.

The payer denied 99212 as unsupported, and 99213 already failed, so before using the last submission I need to determine whether the only supportable E/M level is 99211 or whether the E/M should be removed entirely. I am checking the 99211 E/M rule as the next lower established-patient option.

Agent reasoning
The denial is specifically on the E/M line and the chart/charge history shows an unbilled rapid strep test was added on the prior retry; before using the final submission, I need to correct the E/M level to the only level explicitly documented by the rendering workflow note and ensure the paid diagnostic line remains included. This changes the denied 99212 line to 99214 rather than repeating either prior coding combination.

The denial specifically challenges the E/M level, and we have one submission left, so I need to re-derive the established-patient office visit level from the payer’s E/M rules before resubmitting.

Agent reasoning
The prior partial denial was for unsupported E/M level, and the chart supports an established-patient low-complexity visit for acute pharyngitis with a separately captured rapid strep test. I am correcting the professional service lines to 99213 plus 87880, which differs from both prior submissions and aligns the E/M level with documented MDM.

The corrected coding appears to be the previously unsubmitted combination of 99213 plus 87880, which addresses the denial by including the separately performed rapid strep test and a supportable low-level established E/M.

The current scrub has only blocking NCCI edits requiring modifier 25 on the separately identifiable E/M when billed with rapid strep testing. I will update the service lines to keep the supported 99213 level, add modifier 25 to the E/M, and retain the documented 87880 test with POS 11 and diagnosis pointer 1.
