What P14 means

On a property and casualty claim, the payment for this service is included in another service performed the same day.

This is a property and casualty code, not one a regular health plan uses. It is a bundling decision: the payer treated the service as part of another procedure or visit on the same date and did not pay it separately.

If a policy reference comes with it on the remittance, it identifies the bundling rule applied.

Group codes seen with P14

On a remittance, P14 comes after a group code. These are the ones it is most often reported with:

• CO P14 (Contractual Obligation): The provider's side of the ledger. The reduction comes from the payer contract or a rule the provider has to follow, and the patient normally cannot be billed for it.

The payer chooses the group code for each adjustment, so the same reason code can appear with another group code on your remittance. Read the two together. More about group codes.

Common causes

• The service is a component of a more comprehensive procedure billed the same day.
• A separate visit was billed on the day of a procedure without a modifier.
• The jurisdiction's bundling rules do not allow separate payment.

What to do next

1. Check the bundling rules in the applicable fee schedule for the two services.
2. Resubmit with a modifier and records if the service was truly separate.
3. Post the bundled line as an adjustment if the payer applied the rules correctly.
