A1
Claim/service denied — generic code, use only when no more specific code applies
What This Code Means
A general denial code meant to be used only when a more specific CARC isn’t available; it should always be paired with a remark code explaining the actual reason.
Common Causes
- Payer system defaulted to a generic denial code
- Specific reason not clearly communicated in the remittance
How to Resolve or Appeal
- Check the accompanying remark code(s) for the actual specific reason
- Contact the payer directly if no specific reason is identifiable
