CO-5

Procedure code/type of bill inconsistent with place of service

What This Code Means

The procedure or bill type billed doesn’t match the place-of-service code submitted.

Common Causes

  • Wrong POS code entered for where the service was actually rendered
  • Procedure code only valid for certain settings (e.g. facility vs. non-facility)

How to Resolve or Appeal

  1. Verify the correct place-of-service code for where the service occurred
  2. Correct and resubmit as a corrected claim
