Agent reasoning

First I need to satisfy the requirement to verify active coverage before any billing decisions. The chart mentions the member is active, but I need the formal 270/271 result in the case workflow so coverage is confirmed and any COB details can be reviewed.

I need to capture the actual billable activity from the encounter before assigning CPT/HCPCS, because the charge feed has no codes and I must ensure no documented services are missed.

Agent reasoning

I need the official coding rules before assigning both the ICD-10 and the E/M level, especially since this is an urgent-care established visit with sparse documentation and a possible age inconsistency in the note.

Agent reasoning

The note is internally inconsistent: the registration shows a 52-year-old established patient, but the free-text HPI says '52yo male,' and the eye exam documents 'conjunctiva/sclera clear' despite the complaint of bilateral red, painful, itchy eyes with discharge.

Agent reasoning

I need the exact diagnosis clarified by the resolved provider query before setting ICD-10, because the note text conflicts with the eye exam and the SNOMED needs manual translation. Re-reading the progress note now is to confirm the documented condition, laterality, and any treatment/risk details needed for both ICD-10 selection and E/M leveling.

Agent reasoning

The denial says the documented E/M level is unsupported and hints that captured charges may not match the chart, so before resubmitting I need the coder review to identify whether this urgent care visit should be billed as a lower office/UC E/M or another service construct. I expect this review to surface any documentation gaps, missed billables, or level-of-service concerns specific to this chart.

Agent reasoning

The denial says the billed E/M level is not supported and hints there may be unbilled services, so before changing anything I need the full documentation details in one place to reassess whether this encounter supports any office/UC E/M at all versus a different urgent-care case-rate/global service. I’m re-reading the chart to specifically confirm documented HPI, exam, assessment/plan, and any treatment/orders that would justify a payable code different from the denied 99213.

Agent reasoning

Both prior E/M submissions (99213 and 99212) were denied for unsupported level, and the payer hint says one or more documented services may be unbilled. Before burning the last submission, I need the official E/M leveling rules to determine whether this chart supports a different office/urgent-care coding approach or no payable professional E/M at all.

Agent reasoning

The denial says the documented service may be a different urgent-care service than the E/M line we billed, and I only have one submission left. I need the payer-specific companion/policy now to confirm whether this payer expects an urgent-care global/case-rate code instead of office E/M for POS 20 before changing and resubmitting.

Both prior submissions used office E/M codes, but the guidance explicitly warns that an urgent-care 'global' activity may map to a UC case-rate HCPCS instead of a fee-for-service office E/M. I need to re-open the chart review output now to identify any documented urgent-care global charge/activity or missed billable items that would explain why every office E/M level was denied as unsupported.
