CO 199 Denial Code - Fix Revenue & Procedure Mismatch
CARC 199 indicates that the revenue code and procedure code submitted on the claim do not align. This mismatch means that the procedure billed isn't supported by the revenue code listed, creating a conflict that needs resolution before the claim can be processed.
Who Pays: Group Code Liability
The liability for CARC 199 typically falls under the CO group code, meaning it's a contractual adjustment and the patient should not be billed. However, verify with the payer as some may handle it differently.
Why Claims Get Code 199
- Billing the wrong revenue code for the procedure performed.
- Entering a typographical error in either the revenue or procedure code.
- Using outdated coding manuals or guidelines.
- Incorrect setup of revenue codes in the billing system.
- Mismatch due to payer-specific revenue code requirements.
How to Fix & Resubmit
- Verify that the revenue code and procedure code are correctly paired according to current coding guidelines.
- Check for any typographical errors in the codes entered on the claim.
- Review the payer's specific billing guidelines to ensure compliance with their revenue and procedure code requirements.
- Correct any errors found and resubmit the claim with the appropriate codes.
- If the codes are correct but the denial persists, contact the payer for clarification.
Corrected Claim or Appeal?
For CARC 199, submitting a corrected claim is the usual solution once the error is identified and fixed. An appeal is generally unnecessary unless the payer's guidelines were followed and the denial still occurs.
Preventing Future 199 Denials
- Regularly update coding manuals and reference materials to reflect current guidelines.
- Train billing staff on accurate revenue and procedure code pairing.
- Implement a verification step to check code alignment before claim submission.
