Coding Basics: Medical vs. Pharmacy Benefit

Evrysdi (risdiplam) is typically covered under the pharmacy benefit since it's an oral, self-administered medication. However, understanding both pathways helps ensure proper billing and reduces denials.

Pharmacy Benefit Path (Most Common)

  • Uses NDC codes for billing
  • Requires prior authorization through OptumRx
  • Dispensed via Optum Specialty Pharmacy
  • Patient responsibility based on formulary tier

Medical Benefit Path (Limited Cases)

  • Uses HCPCS J8499 ("Prescription drug, oral, non-chemotherapeutic, not otherwise specified")
  • May apply for certain Medicaid programs or specific plan designs
  • Requires detailed documentation and medical necessity justification
Tip: Verify benefit design with UnitedHealthcare before submission. Self-funded employer plans may have different coverage pathways than fully-insured plans.

ICD-10 Mapping for SMA

Accurate ICD-10 coding is crucial for Evrysdi approval. Use the most specific code supported by your documentation.

Primary ICD-10 Codes for SMA

ICD-10 Code Description Documentation Requirements
G12.0 Infantile spinal muscular atrophy, type I Genetic confirmation, early onset symptoms, Werdnig-Hoffmann features
G12.1 Other inherited spinal muscular atrophy Genetic confirmation, later onset, types II-IV
G12.9 Spinal muscular atrophy, unspecified Only when genetic results pending—avoid as default

Documentation Words That Support Coding

  • "Homozygous deletion of SMN1 exon 7"
  • "SMN2 copy number: [X] copies"
  • "Genetic counseling completed"
  • "Progressive muscle weakness"
  • "Lower motor neuron signs"
  • "Baseline motor assessment completed"
Note: Never use G12.9 (unspecified) without clear justification. Payers flag this code for additional review, increasing denial risk.

Product Coding: HCPCS, J-Codes, and NDCs

NDC Codes for Evrysdi

  • NDC 50242-175-07: 60 mg/80 mL oral solution (most common)
  • NDC 50242-215-01: 5 mg tablets (for patients ≥20 kg)

HCPCS Coding

  • J8499: For medical benefit billing
  • Include detailed description: "Evrysdi (risdiplam) oral solution"

Units and Dosing Math

Evrysdi dosing is weight and age-based:

Patient Category Dose Volume Calculation
<2 months 0.15 mg/kg daily (Weight × 0.15) ÷ 0.75 mg/mL
2 months to <2 years 0.20 mg/kg daily (Weight × 0.20) ÷ 0.75 mg/mL
≥2 years, <20 kg 0.25 mg/kg daily (Weight × 0.25) ÷ 0.75 mg/mL
≥2 years, ≥20 kg 5 mg daily (flat dose) 6.7 mL daily or one 5 mg tablet

Critical: Always round liquid doses to nearest 0.1 mL and document the calculation method.

Frequent Coding and Billing Pitfalls

Common Errors That Trigger Denials

Error Type Problem Solution
Weight Documentation Outdated or missing weight Use weight from within 30 days of prescription
Unit Conversion Pounds instead of kilograms Always convert to kg: weight (lbs) ÷ 2.2
Dose Calculation Math errors in mg or mL Double-check: mg dose ÷ 0.75 = mL volume
ICD-10 Mismatch Generic G12.9 without justification Use specific code matching genetic results
Concurrent Therapy Billing with active Spinraza Document discontinuation of other SMA treatments

Documentation Red Flags

  • Missing genetic confirmation
  • Baseline motor scores >6 months old
  • Concurrent SMN-targeting therapies
  • Incomplete neurologist consultation
  • Dosing exceeding FDA maximums
From our advocates: We've seen cases where a simple weight conversion error (using 44 lbs instead of 20 kg) resulted in a calculated overdose that triggered an automatic denial. Always double-check your math and include the calculation method in your documentation.

Verification with UnitedHealthcare Resources

Before Submitting Your Request

  1. Check Formulary Status
  2. Confirm PA Requirements
  3. Validate Coding
    • Confirm NDC numbers match current packaging
    • Cross-reference ICD-10 codes with genetic results
    • Verify prescriber NPI and specialty designation
