How to Get Ilaris (Canakinumab) Covered by Aetna CVS Health in Ohio: Complete Prior Authorization and Appeals Guide

Answer Box: Getting Ilaris Covered by Aetna CVS Health in Ohio

Aetna CVS Health requires prior authorization for all Ilaris (canakinumab) uses using their Ilaris Injectable Medication Precertification Request form and clinical policy CPB 0881. First step today: Have your rheumatologist or immunologist complete the precert form with your exact ICD-10 diagnosis code (e.g., M06.1 for adult-onset Still's disease), document all prior failed therapies, and submit via Availity portal or fax to 1-866-249-6155 for specialty drugs. If denied, Ohio residents have 180 days to request external review through the Ohio Department of Insurance.

Coding Basics: Medical vs. Pharmacy Benefit Paths

Ilaris (canakinumab) is typically covered under your medical benefit as a provider-administered injectable, not through pharmacy benefit like oral medications. This means:

  • HCPCS J-code billing: Clinics bill using J0638 (Injection, canakinumab, 1 mg)
  • Site of administration: Usually office-based (place of service 11) or hospital outpatient
  • Prior authorization required: All Aetna plans require PA regardless of indication
Note: Some Aetna plans route Ilaris through CVS Specialty Pharmacy for "white bagging" to the clinic, but the PA process remains the same.

ICD-10 Mapping for Common Ilaris Indications

Accurate diagnosis coding is crucial for Ilaris approval. Here are the primary ICD-10 codes Aetna accepts:

Condition ICD-10 Code Documentation Keywords
Adult-onset Still's disease M06.1 (specify site: M06.10 multiple sites, M06.19 unspecified) Quotidian fever >102°F, salmon-colored rash, polyarthritis, elevated ferritin
Systemic juvenile idiopathic arthritis M08.2x (with site specificity) Systemic features, fever, rash, arthritis in pediatric patients
Cryopyrin-associated periodic syndromes (CAPS) M04.2 or specific CAPS codes Familial cold autoinflammatory syndrome, Muckle-Wells syndrome, NOMID
TNF receptor-associated periodic syndrome M04.1 Recurrent fever episodes, abdominal pain, skin lesions
Gout flares (restricted use) M10.x (site-specific) Acute gout attacks, failed standard therapy, contraindications to alternatives

Documentation requirements for Still's disease (M06.1) should include:

  • Yamaguchi criteria scoring (≥5 points probable, ≥7 definite)
  • Fever logs showing quotidian pattern
  • Photos or detailed descriptions of evanescent rash
  • Laboratory values: ferritin >1000 ng/mL, elevated ESR/CRP
  • Negative ANA and rheumatoid factor

HCPCS/J-Code and NDC Overview

HCPCS Billing Code

  • J0638: Injection, canakinumab, 1 mg
  • Billing units: 1 unit = 1 mg (so 150 mg dose = 150 units)

Dosing by Indication and Billing Units

Indication Dose Frequency Max Units per Dose
CAPS 150 mg Every 8 weeks 150 units
Still's disease/SJIA 4 mg/kg (max 300 mg) Every 4 weeks 300 units
Gout flares 150 mg Single dose per flare 150 units
Other periodic fever syndromes 2-8 mg/kg Every 4-8 weeks Varies by weight

NDC Numbers

  • 150 mg/mL prefilled syringe: 0078-0734-15
  • 150 mg/mL vial: 0078-0733-15

Clean PA Request Anatomy

A successful Aetna Ilaris PA request includes these components:

1. Prescriber Information

  • Must be a specialist (rheumatologist, immunologist, or dermatologist)
  • NPI number and Aetna provider status

2. Patient Demographics and Insurance

  • Aetna member ID and group number
  • Date of birth and contact information

3. Clinical Information Section

Diagnosis: Adult-onset Still's disease
ICD-10: M06.1 (multiple sites)
Indication: FDA-approved for Still's disease
Dose: 4 mg/kg (patient weight: 70 kg = 280 mg) subcutaneous
Frequency: Every 4 weeks

4. Prior Therapy Documentation

Document each required step-therapy agent:

  • NSAIDs: "Tried ibuprofen 800 mg TID x 6 weeks - inadequate response, continued fever/rash"
  • Corticosteroids: "Prednisone 40 mg daily x 4 weeks - temporary improvement but unable to taper without flare"
  • Methotrexate: "15 mg weekly x 12 weeks - discontinued due to nausea and elevated liver enzymes"

5. Medical Necessity Statement

"Patient has refractory adult-onset Still's disease with active systemic features including quotidian fever, evanescent rash, and polyarthritis despite adequate trials of NSAIDs, corticosteroids, and methotrexate. Ferritin remains elevated at 2,400 ng/mL. Ilaris is FDA-approved for this indication and expected to provide disease control while allowing steroid taper."

Frequent Coding Pitfalls

Unit Conversion Errors

  • Wrong: Billing 1 unit for 150 mg dose
  • Correct: Billing 150 units for 150 mg dose (J0638 = 1 mg per unit)

Mismatched ICD-10 Codes

  • Wrong: Using M79.3 (panniculitis) for Still's disease rash
  • Correct: Using M06.1 with supporting documentation of systemic features

Missing Start Dates

  • Always include "Date of first dose requested" on PA forms
  • Aetna may deny incomplete temporal information

Inadequate Step-Therapy Documentation

  • Wrong: "Patient failed multiple prior therapies"
  • Correct: "Patient tried naproxen 500 mg BID x 8 weeks (inadequate response), prednisone 30 mg daily x 6 weeks (unable to taper), methotrexate 20 mg weekly x 16 weeks (discontinued for hepatotoxicity - ALT 89 U/L)"

From our advocates: We've seen several Ohio patients successfully overturn Ilaris denials at the external review level by submitting comprehensive documentation of disease severity and failed alternatives. The key is addressing each specific denial reason with clinical evidence and guideline citations.

FAQ

How long does Aetna CVS Health PA take for Ilaris in Ohio? Standard PA decisions take 30-45 days. Expedited reviews (when delay could jeopardize health) are completed within 72 hours.

What if Ilaris is non-formulary on my Aetna plan? You can request a formulary exception with medical necessity documentation. The process is the same as standard PA but requires stronger justification for why formulary alternatives won't work.

Can I request an expedited appeal in Ohio? Yes, if waiting for standard review could seriously jeopardize your health. Your prescriber must certify the urgency in writing.

Does step therapy apply if I failed therapies outside Ohio? Yes, Aetna accepts documented treatment failures from any location. Include complete medical records from previous providers.

What's the success rate for Ilaris appeals with Aetna? While specific rates aren't published, high-cost specialty biologics have higher overturn rates when appeals include comprehensive medical necessity documentation and address each denial criterion.

How much does Ilaris cost without insurance? Cash prices typically range $20,000-$23,000 per 150 mg dose. Novartis offers patient assistance programs for eligible patients.

Can I use Novartis copay assistance with Aetna? Copay assistance availability depends on your specific plan type. Commercial plans typically allow manufacturer assistance, while government plans (Medicare/Medicaid) may not.

What if my employer plan is self-funded? Self-funded ERISA plans may not be subject to Ohio's external review process, but many voluntarily offer similar independent review procedures.
