ICD-10 Coding for MS Documentation

Effective October 2025, MS coding became more specific. Your neurologist must use the correct codes:

Primary Codes for Rebif

  • G35.A: Relapsing-remitting multiple sclerosis (RRMS)
  • G35.C1: Secondary progressive multiple sclerosis, active
  • G35.C0: Secondary progressive multiple sclerosis, unspecified

Documentation Requirements

Your medical records must clearly document:

  • MS phenotype (relapsing-remitting vs. secondary progressive)
  • Disease activity (for SPMS, specify if active or non-active)
  • Relapse history with dates and severity
  • MRI findings showing lesions consistent with MS
  • Prior DMT trials and outcomes
Clinician Corner: The old single code G35 is no longer valid. Incomplete documentation may trigger payer requests for clarification, delaying approval.
