N851 Remark Code - Payment Reduced for Therapy Assistant

The N851 remark code indicates that the payment has been reduced due to services being provided by a therapy assistant. This means that the payer recognizes the service was delivered, but the reimbursement amount is lower because it was not performed by a licensed therapist.

How It Relates to the Denial

The N851 remark code typically accompanies claim adjustment reason codes related to reduced payment amounts. The combination signals that the payer is adjusting the reimbursement based on the qualifications of the provider who delivered the therapy services.

Common Scenarios

1A physical therapy claim was submitted for 10 sessions, but the remittance shows a reduced payment with the N851 remark code.
→ In this case, the N851 indicates that payment was lowered because a therapy assistant provided some or all of the therapy services, which may not meet the criteria for full reimbursement.
2A claim for occupational therapy services indicates a certain amount billed, but the remittance shows an adjustment with the N851 remark code attached.
→ Here, the N851 suggests that the reduction in payment is due to the involvement of a therapy assistant, indicating that reimbursement policies may require a licensed therapist for full payment.
3A speech therapy service was billed, and the provider's remittance includes a note of reduced payment along with the N851 remark code.
→ The N851 remark code in this context means the payer has adjusted the payment amount because the services were performed by a therapy assistant instead of a licensed speech therapist.

What to Do

  1. Review the qualifications of the provider who delivered the therapy services to ensure compliance with payer requirements.
  2. Check if the services were appropriately billed under the supervision of a licensed therapist if applicable.
  3. Consider resubmitting the claim with a different provider type if the billing guidelines allow for a higher reimbursement.

What to Check

  • The claim details to verify who provided the therapy services and their qualifications.
  • The payer's policy regarding reimbursement for services performed by therapy assistants.
  • The original claim adjustment reason code that accompanies the N851 remark code to understand the full context of the payment reduction.
