What N607 means

A workers’ compensation or injury claim covers specific accepted conditions. When a provider treats something else, such as an unrelated illness or a body part the carrier has not accepted, those services fall outside the claim. N607 tells you the service was for a non-compensable condition.

It is often paired with CARC P4 (non-compensable) or CARC 219 (extent of injury).

Common causes

  • Diagnosis codes on the bill point to a condition not accepted on the claim.
  • A new body part was treated before the carrier accepted it.
  • A pre-existing or unrelated condition was treated during an injury visit.
  • The carrier denied part of the claim and the provider wasn’t told.

What to do

  1. Ask the adjuster which conditions and body parts are accepted on the claim.
  2. Review the diagnoses on your bill. If an accepted condition was coded incorrectly, submit a corrected bill.
  3. Bill the unrelated care to the patient’s health insurance with the carrier’s denial if needed.
  4. Support a dispute if the patient or their attorney challenges the carrier’s decision.

How to prevent it

Record accepted conditions at the start of a workers’ comp case and update them when the carrier changes its position. Bill unrelated care separately from the start.

Codes that may appear with N607

  • CO-P4 (Workers' Compensation claim adjudicated as non-compensable.): The workers' compensation claim or service was adjudicated as non-compensable.
  • CO-219 (Based on extent of injury.): Based on extent of injury.
  • N576 (Services not related to the specific incident/claim/accident/loss being reported.): Services are not related to the specific incident or loss.
  • N597 (Adjusted based on a medical/dental provider's apportionment of care between related injuries and other unrelated medical/dental conditions/injuries.): Payment apportioned between related and unrelated conditions.
  • CO-P2 (Not a work related injury/illness and thus not the liability of the workers' compensation carrier): Not a work-related injury, so not the workers' compensation carrier's liability.

N607 FAQ

What does non-compensable mean?

In workers' compensation, it means the condition is not accepted as caused by the work injury, so the employer's carrier does not owe benefits for it.

Can the patient's health plan pay?

Often yes, for conditions the workers' comp carrier has formally denied. The health plan may ask for the denial.

Can the decision be challenged?

The injured worker can usually dispute it through the state's workers' compensation system. The provider can support that with records.
