Not an ICD-10 code. RARC N16 is a remittance-advice remark code published by X12 and carried on the 835 LQ segment. Any ICD-10 code with the same letters and digits (e.g., ICD-10 M15 osteoarthritis, N130 other urinary tract disorders) is a separate, unrelated code set used in diagnoses on the 837. Confirm the context before acting on this page.

TL;DR

RARC N16 (X12 Family/member Out-of-Pocket maximum has been met. Payment based on a higher percentage). RARC N16 indicates the family/individual OOP max has been reached — payer now pays at a higher percentage.

What RARC N16 actually means

RARC N16 indicates the family/individual OOP max has been reached — payer now pays at a higher percentage. Informational, not a denial.

Common root causes

  • OOP maximum reached for the benefit year.

Prevention checklist

  • OOP tracking for patient financial counseling.

Resolution & appeal strategy — step by step

Because RARC N16 is supplemental to a CARC, the resolution path usually starts by fixing the underlying adjustment reason. A formal appeal of the RARC alone is rarely necessary.

Frequently asked questions — RARC N16

What does RARC N16 mean?

RARC N16 is an X12 Remittance Advice Remark Code. The official X12 definition is: "Family/member Out-of-Pocket maximum has been met. Payment based on a higher percentage." It is supplemental to a Claim Adjustment Reason Code (CARC) on the same 835 line.

How do I resolve a RARC N16 remark on a remit?

Start from the root cause: OOP maximum reached for the benefit year. First step: Not applicable — informational. Because RARCs are supplemental, the resolution is almost always to address the paired CARC rather than appeal the RARC alone.

Where does RARC N16 appear on the 835 ERA?

RARC N16 is carried on the 835 Loop 2110 LQ segment alongside the CARC in the CAS segment of the same service line. The code and its X12 description also print on the paper EOB in the "Remark Code" or "Remark" column next to the corresponding denial or adjustment reason.

Is RARC N16 the same as ICD-10 code N16?

No. RARC N16 is a remittance-advice remark code published by X12 and carried on the 835. Any ICD-10 code with the same letters and digits is a diagnosis code on the 837 HI segment — a completely different code set maintained by the WHO/CMS. Use the transaction context (835 = RARC; 837 = ICD-10) to disambiguate.
