N381: Alert: Consult our contractual agreement for restrictions/billing/payment information related to this service
The payer is pointing to a specific term in the network provider contract, such as a bundled rate or carve-out, rather than a general coding problem. The answer to why payment was adjusted lives in the contract itself.
Corrective actions
- 1
Pull the specific contract clause
Locate the fee schedule attachment or service-specific carve-out language in the provider agreement that applies to this code or service line.
- 2
Escalate to contracting if the adjustment looks wrong
If the contract language does not support the adjustment applied, route the claim to your contracting or payer relations team rather than resubmitting the same claim repeatedly.
