Sometimes, but a separate E/M service must be significant and separately identifiable from the work included in the procedure. Modifier 25 is not an automatic addition to every injection visit. Review the documentation, current CPT guidance and payer rules for the service actually performed.

## Identify the work beyond the procedure

CMS E/M guidance describes modifier 25 for a separately identifiable evaluation and management service on the same day. Routine work inherent in the procedure does not become separately billable just because it appears under another heading in the chart.

## Keep an auditable clinical explanation

The treating professional should document the evaluated concern, findings, assessment and management that support the additional service. A separate diagnosis may not be required in every case, but an extra diagnosis is not a substitute for separate work. The reviewer should be able to explain the decision from the record.

## Practical checklist

1. Identify the E/M work and the procedure’s included work.
2. Review the signed record for the separately identifiable service.
3. Confirm code, modifier and payer requirements together.
4. Record why separate reporting is supported or remove the unsupported charge.

## Worked example

A scheduled injection includes routine interval questions and consent. That alone is not a reason to add an office-visit charge. If a separate problem was assessed and managed, the coder needs the actual documentation before considering separate reporting.

## Mistakes to avoid

- Adding modifier 25 to every injection encounter by default.
- Writing a separate paragraph solely to justify an extra charge.
- Treating a new-patient label as automatic justification.
