What N448 means

The payer has no price for this item in the fee schedule or contract it used, so the line was not paid as billed.

N448 means the payer looked for the code in the fee schedule or contract it uses for you and did not find it. That can mean the item is not payable under that arrangement, or that it needs special pricing.

It usually accompanies a reason code such as 96 or 16. Check the contract before assuming the service is simply not covered.

Common causes

• A new drug or supply code has not been added to the payer's fee schedule.
• Your contract covers a defined list of services and this one is not on it.
• The item should have been billed with a different code that is on the schedule.

What to do next

1. Check your contract and fee schedule for the code and date of service.
2. Ask provider relations whether the code needs manual pricing or an invoice.
3. Rebill under a listed code if one correctly describes the item.
4. Raise repeat gaps with the contracting team.
