Reason Code 50 | Remark Code N180

Code Description
Reason Code: 50 These are non-covered services because this is not deemed a 'medical necessity' by the payer.
Remark Code: N180 This item or service does not meet the criteria for the category under which it was billed.


Common Reasons for Denial

  • Claim is missing a Certificate of Medical Necessity or DME Information Form (Required for dates of service prior to January 1, 2023 only).
  • Claim is missing the KX modifier.
  • This is not a service covered by Medicare.

Next Step

  • If the remittance advice reason includes MA130, correct claim and rebill
  • If CMN/DIF was submitted with claim, a redetermination request may be submitted with all relevant supporting documentation. Noridian encourages Redeterminations/Appeals be submitted using the Noridian Medicare Portal. Review applicable Local Coverage Determination (LCD), LCD Policy Article, and Documentation Checklists prior to submitting request.
  • If the KX modifier was omitted by mistake, request a Redeterminations/Appeals to add, change, or remove the KX (the same is true for GA, GZ, GY modifiers). Be sure to include all the appropriate documentation.
