CO-282: Procedure/Revenue Code Inconsistent with Type of Bill

What Does CO-282 Mean?

CO-282 means the billing error is the provider's responsibility. The procedure/revenue code does not align with the type of bill, and the provider must fix and resubmit. The patient cannot be billed for this denial — it is a coding issue that the provider must resolve.

CARC 282 indicates a technical billing error where the procedure or revenue code submitted on the claim is inconsistent with the type of bill (TOB). This is a structural mismatch — certain codes are only valid with specific bill types, and the payer's system flagged the inconsistency during claim processing.

Common examples include billing an outpatient procedure code on an inpatient bill type, using a revenue code that is not valid for the submitted bill type classification (inpatient, outpatient, SNF, home health, etc.), or selecting the wrong type of bill in the billing system altogether. These errors are typically data entry mistakes or billing system configuration issues rather than clinical documentation problems.

The 835 Healthcare Policy Identification Segment (loop 2110 Service Payment Information REF) often provides additional detail about which specific code triggered the inconsistency. This code is a straightforward billing correction — fix the mismatch and resubmit. Appeals are not appropriate because this is a correctable coding error.

Common Causes

How to Resolve

Identify the code-to-bill type mismatch using the 835 remittance, correct the error, and resubmit as a corrected claim.

1. Review the 835 remittance Check the Healthcare Policy Identification Segment for the specific code causing the inconsistency.
2. Identify the correct combination Determine whether the procedure/revenue code or the type of bill needs to change by consulting coding guidelines.
3. Correct in your billing system Update the code or bill type to the correct value in your practice management system.
4. Resubmit as corrected claim Submit the corrected claim — do not submit as a new claim.

How to Prevent CO-282

• Implement automated edits that flag procedure/revenue code and type of bill mismatches before claim submission
• Train billing staff on correct relationships between codes and bill types for institutional claims
• Conduct regular coding audits to catch systemic mismatch patterns
• Keep code-to-bill type reference tables current in your billing system

General Prevention

• Implement automated edits in your billing system that flag procedure/revenue code and type of bill mismatches before claim submission
• Train billing staff on the correct relationships between procedure codes, revenue codes, and bill types for institutional claims
• Maintain up-to-date code-to-bill type reference tables in your billing system
• Stay current with coding guideline updates that may change valid code-bill type combinations
