Procedure code billed is not correct/valid for the services billed or the date of service

What Does This Code Mean?

The specific procedure code doesn’t match the documented services, or isn’t valid for the billed date.

Common Causes

  • Wrong CPT code selected for the service actually performed
  • Code retired/changed as of the date of service

Recommended Next Steps

  1. Cross-check the code against the documentation and the effective code set for that date
  2. Correct and resubmit as a corrected claim
