How to appeal a Missing or Invalid Information denial
This denial means the claim is missing or has invalid information the payer needs to adjudicate it, from a member ID to a required modifier or referring provider.
Common code: CARC 16 (claim lacks information)Why payers issue it
- A required field was blank, wrong, or mistyped (member ID, NPI, DOB)
- A RARC on the remit points to the specific missing element
- Referring or rendering provider info didn't match payer records
- An expected modifier or authorization number was absent
What overturns it
- Read the RARC to find exactly what's missing, then correct and resubmit
- Verify member, provider, and eligibility data against the payer's records
- Add the required modifier, auth, or referring-provider detail
- Resubmit as a corrected claim, not a new one, when the payer requires it
Worth appealing? These are the cheapest to recover, the work was valid, the data just needs fixing, but they pile up because no one has time to chase each one.
