N670 Remark Code - Medicare MPPR Explanation
The N670 remark code indicates that the billed service code is recognized as the primary procedure subject to the Medicare Multiple Procedure Payment Reduction (MPPR) rule. This typically means that the payment for this service has been reduced due to the application of the MPPR policy, which affects how certain services are reimbursed when multiple procedures are performed during a single session.
How It Relates to the Denial
The N670 remark code usually accompanies a claim adjustment reason code that explains the payment reduction related to the MPPR. This combination signals that the provider should be aware of the specific Medicare policy impacting the reimbursement for the primary procedure code billed.
Common Scenarios
1A physical therapy clinic submits a claim for multiple therapy sessions performed on the same day, including a primary procedure code for manual therapy.
→ The N670 remark code suggests that the primary procedure code for manual therapy is subject to MPPR, indicating that the payment may have been reduced in accordance with Medicare's policy.
2An outpatient surgical center bills for a surgical procedure along with several related follow-up services, with the primary procedure indicated on the claim.
→ Here, the N670 remark code highlights that the primary procedure billed is subject to MPPR, which likely resulted in a reimbursement adjustment reflecting that policy.
3A radiology department processes a claim for a CT scan and an MRI performed in the same session, with the CT scan as the primary procedure code.
→ The presence of the N670 remark code indicates that the CT scan is recognized as the primary procedure and is subject to MPPR, leading to a potential reduction in the payment for that service.
What to Do
- Review the claim adjustment reason code to understand the specific reduction applied due to MPPR.
- Ensure that the billing reflects the correct application of the MPPR policy for the primary procedure code.
- If necessary, adjust future claims to account for the MPPR when multiple procedures are billed.
What to Check
- Verify the MPPR policy details in the Medicare billing guidelines.
- Check the procedure codes billed to confirm which is designated as the primary procedure.
- Review the payment history for similar claims to see how MPPR was applied previously.
