CARC/RARC |
DESCRIPTION |
CO-236 |
This procedure or procedure/modifier combination is not compatible with another procedure or procedure/modifier combination provided on the same day according to the National Correct Coding Initiative or workers compensation state regulations/ fee schedule requirements. |
Common Reasons for Message
- Combination of codes billed on same date of service by same provider may not be appropriately paired together due to National Correct Coding Initiative (NCCI) Edits
- Payment for service billed is bundled into payment for another service performed that day
- It is unusual for services billed to be performed together
- Modifier used to unbundle is on incorrect code or incorrect modifier was used
Next Step
- Verify code set is appropriate to be billed together
- Submit Appeal request to add modifier, if appropriate
- See Appeals webpage for instructions on how to submit a Reopening or Redetermination
- Providers may not bill patient for NCCI edit denials
- Denial is based on incorrect coding
- Providers should not complete an ABN for NCCI edits
Claim Submission Tips
- Review NCCI Coding Edits prior to submitting claim to determine if codes are appropriately paired
- When appropriate, modifier to identify separately identifiable service should be appended to Column 2 code
- Modifier Indicator "0" - there are no circumstances in which both procedures of a code pair should be paid; modifier is not allowed for NCCI purposes
- Modifier Indicator "1" - modifiers associated with NCCI are allowed with this code pair when appropriate
- Modifier Indicator "9" - NCCI edit does not apply to this code pair; edit for code pair was deleted retroactively
