Modifier lookup tool

This tool provides information for most procedure code modifiers used by Medicare. Enter the four required fields and be presented with modifier details such as description, indicators, effective dates, payer information, and more. Note: Existence of a valid procedure/modifier combination does not imply coverage.

Alert Note: Data issues have been identified on this tool and we are diligently working to restore full functionality. Until issues are resolved, we recommend cross checking the Medicare Claims Processing Manual for additional information on modifiers.
