CO 110 Denial Code: Fix Billing Date Errors
Code 110 indicates that the claim was submitted with a billing date that is earlier than the service date. This error typically occurs when the dates are entered incorrectly during the claim preparation process.
Who Pays: Group Code Liability
For code 110, the adjustment typically falls under the CO group code, meaning it is a provider write-off and the patient cannot be billed for this error.
Why Claims Get Code 110
- Incorrect entry of billing date in the claim form.
- Software glitch causing date misalignment.
- Manual data entry errors during claim submission.
- Miscommunication about service dates between provider and billing department.
How to Fix & Resubmit
- Verify the service date and billing date on the original claim form.
- Correct the billing date to ensure it is after the service date.
- Resubmit the corrected claim to the payer.
- Confirm acceptance of the corrected claim by monitoring remittance advice.
- If denial persists, contact the payer for further clarification.
Corrected Claim or Appeal?
For code 110, submitting a corrected claim is the appropriate action once the billing date is fixed. An appeal is not necessary unless the payer continues to deny after correction.
Preventing Future 110 Denials
- Implement a date verification step in the billing process before claim submission.
- Train staff on common date entry errors to watch for during claim preparation.
- Utilize claim submission software with built-in date validation checks.
- Establish clear communication channels between service providers and billing staff to confirm accurate dates.
