			| 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
