Check first
Check these before anything else
- Which payer holds coverage for the date of service
- Payer ID and submission address used
- Plan type (medical / dental / pharmacy)
- Whether the claim was already paid elsewhere
- CARC 109 and the accompanying remark code
Verify payer-specific rules: Heads up

What it means
The claim reached a payer that does not hold the coverage for the service or date — the wrong payer was billed, the wrong payer ID or address was used, or the service belongs under a different plan type (medical, dental, pharmacy). The claim needs to go to the correct payer, and you must confirm it was not paid twice along the way.
AR Guide knowledge
Common causes
- Claim sent to the wrong payer or contractor
- Wrong payer ID or submission address used
- Coverage actually held by another plan
- Service billed to the wrong plan type (dental vs. medical, etc.)
- Coverage changed since the last visit
AR Guide knowledge
What AR should verify
- Verify which payer holds coverage for the date of service
- Confirm the payer ID and submission address used
- Check whether the claim was already paid by another payer
- Confirm the correct plan type for the service
Recommended workflow
What to do next
- Send the claim to the correct payer
- If already billed elsewhere, confirm it was not paid twice
- For forwarded claims, monitor the new payer's processing
Don’t assume
Avoid these shortcuts
- The claim was sent to the right payer
- The payer ID on file is current
- A different plan type covers the same service
- The claim cannot be paid twice — verify it
- The original payer will forward it automatically
AR Guide knowledge
Documentation
- Eligibility confirmation showing the correct payer
- The corrected claim with the correct payer ID
- Any forwarding correspondence from the original payer

Escalation
- Eligibility: confirm the correct payer and plan for the service
- Client: when patient coverage information was not provided accurately
- Supervisor: when a payer refuses to forward or acknowledge the error
QA checkpoint
Confirm before closing
- Verify the payer at eligibility check-in and before submission
- Keep payer IDs and submission addresses current in the system
- Confirm coverage changes between scheduling and service date
