CARC 10: The diagnosis is inconsistent with the patient's age

The billed diagnosis doesn't match the patient's age — for example, a pediatric condition billed for an adult.

What this means for your claim

Automated claim edits flag diagnoses that are age-specific. This is often a coding error that can be corrected with a resubmission.

What to do next

  1. 1

    Ask your provider to verify the patient's date of birth on the claim and the ICD-10 code used.

  2. 2

    If the diagnosis is genuinely appropriate for your age despite an age-based edit, ask your provider to appeal with clinical documentation.

  3. 3

    Check for data entry errors in the claim — a wrong birth year is a common root cause.
