N357Remark Code (RARC)Active
N357 Remark Code - Time Frame Requirements Not Met
The N357 remark code indicates that the time frame requirements between the billed service or supply and a related service or supply have not been fulfilled. This means that the payer has determined that the timing of the services does not align with their policy regarding related procedures.
How It Relates to the Denial
The N357 remark code typically accompanies an adjustment reason code that indicates a reduction or denial due to timing issues. The combination signals that the service billed is considered related to another service, and the payer expects a specific time frame between the two to be adhered to, which was not met.
Common Scenarios
1A provider billed for a follow-up therapy session shortly after an initial evaluation, but the claim was denied due to timing issues.
→ In this scenario, the N357 remark code suggests that the follow-up session was billed too soon after the prior service, violating the payer's time frame requirement for related services.
2A claim for a diagnostic test was submitted, but the associated treatment was performed outside of the allowable time frame, leading to a denial.
→ The N357 remark code in this case indicates that the diagnostic test was not eligible for reimbursement because it was not performed within the specified time frame of the related treatment.
3A patient received a surgical procedure and then had a follow-up visit too quickly, resulting in a partial payment for the follow-up service.
→ Here, the N357 remark code clarifies that the follow-up visit's payment was reduced because it did not meet the required time interval from the surgical procedure.
What to Do
- Review the time frames established by the payer for related services or procedures.
- Consider rescheduling the service to comply with the payer's time frame requirements.
- If applicable, provide documentation supporting the necessity of the timing of the services.
What to Check
- The payer's policy on time frame requirements for related services.
- The claim adjustment reason code that accompanies the N357 remark code.
- Any clinical documentation that may justify the timing of the services provided.
