CARC 107: The related or qualifying claim/service was not identified on this claim
A required reference to a related claim (like a referring provider or parent claim) is missing.
What this means for your claim
Some claims require a cross-reference to a previous service, authorization, or qualifying claim. Without it, the system can't link the claims together.
What to do next
- 1
Ask your provider to identify and include the qualifying claim number or authorization reference.
- 2
Resubmission with the correct cross-reference typically resolves this automatically.
- 3
Follow up to confirm a new EOB is issued after the corrected claim is processed.
