Claim/service denied — generic code, use only when no more specific code applies

What Does This Code Mean?

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

Recommended Next Steps

  1. Check the accompanying remark code(s) for the actual specific reason
  2. Contact the payer directly if no specific reason is identifiable
