What does denial code CARC 109 mean?

The claim or service isn't covered by this payer; it should be sent to the correct payer or administrator, often a behavioral-health carve-out.

What is a behavioral health carve-out?

An arrangement where a health plan hands its mental health and substance use benefits to a separate company, which then processes those claims.

Wrong-payer denials.

A wrong-payer denial is a claim denied because a different payer is responsible, often a behavioral-health company that administers the plan's mental health benefits.

Why it happens

Many health plans carve out behavioral health to a separate administrator. Claims sent to the medical plan come back denied, and the practice has a limited time to send them to the right one.

How Owed checks

01
Owed finds lines denied with CARC 109 (claim not covered by this payer) and totals what they should have paid.
02
It sets a deadline 90 days from the date of service, a conservative default for resubmitting to the right payer before its filing limit.

What you'll see

The denied lines and what they should have paid
The resubmission deadline

Rules decide, never AI: the same file always gives the same findings, and every finding shows its math.

What to do

Verify eligibility and coordination of benefits, then submit the claim to the responsible payer or behavioral-health administrator before its timely filing limit.
