N52 Remark Code - Patient Not Enrolled in Managed Care Plan

The N52 code indicates that the patient was not enrolled in the billing provider's managed care plan at the time the service was provided. This remark clarifies the reason for the adjustment made to the claim, pointing out the patient's eligibility status on the date of service.

How It Relates to the Denial

Typically, the N52 remark accompanies reason codes that relate to payment adjustments based on eligibility or enrollment issues. It signals that the claim was not processed favorably due to the patient's lack of enrollment in the relevant managed care plan.

Common Scenarios

1A patient received a routine check-up billed under a managed care plan, but the payment was denied due to enrollment issues. The remittance included a reason code indicating a payment adjustment.
→ The presence of the N52 remark means that the payer is stating the patient was not enrolled in the managed care plan at the time of the check-up, supporting the denial of the claim.
2A claim for physical therapy services was submitted, but the remittance returned with a payment adjustment and the N52 remark. The patient had been a member of the plan previously.
→ This remark indicates that the patient’s enrollment in the billing provider's managed care plan had lapsed by the date of service, which is the reason for the adjustment.
3A surgical procedure was billed to a managed care plan, but the claim was denied with a reason code for eligibility issues, accompanied by the N52 remark.
→ The N52 remark clarifies that the patient was not enrolled in the provider's managed care plan on the procedure date, thus justifying the denial.

What to Do

  1. Verify the patient's enrollment status on the date of service with the managed care plan.
  2. Consider contacting the patient to discuss their coverage and enrollment options.
  3. If applicable, resubmit the claim with correct enrollment information or seek payment from the patient.

What to Check

  • The eligibility response from the payer to confirm the patient's enrollment status.
  • The managed care plan documentation for the coverage details on the date of service.
  • The claim submission details to ensure accurate billing to the correct plan.
