Plan Types and Coverage Differences

Aetna CVS Health offers different plan structures in New York that affect how you access Rebif:

HMO Plans: Require a referral from your primary care physician before seeing a neurologist. However, Aetna Open Access HMO plans allow specialist visits without referrals. HMO referrals are valid for 90 days when required.

PPO Plans: No referrals needed. You can see any participating neurologist directly, though you'll pay more for out-of-network providers.

EPO Plans: Referral requirements vary by specific plan. Some Aetna EPO plans require specialty referrals while others don't. Check your Summary of Benefits to confirm.

All plan types require Rebif to be dispensed through CVS Specialty Pharmacy and need prior authorization regardless of your plan structure.

Formulary Status and Tier Placement

Rebif typically appears on Aetna CVS Health formularies but requires prior authorization before dispensing. The medication is classified as a specialty drug due to its high cost (frequently over $10,000 per 12-syringe carton) and complex administration requirements.

Step Therapy Considerations: Aetna may require you to try preferred disease-modifying therapies first before approving Rebif. Common first-line DMTs include:

  • Interferon beta-1a (Avonex)
  • Glatiramer acetate (Copaxone)
  • Oral DMTs like dimethyl fumarate (Tecfidera)

Override Options: Step therapy can be bypassed with documentation of:

  • Medical contraindications to preferred agents
  • Previous treatment failures or intolerances
  • Clinical reasons why Rebif is specifically indicated
