Why New York State Rules Matter

New York's insurance laws provide some of the strongest patient protections in the nation, especially for specialty medications like Nourianz. While Aetna CVS Health sets its own formulary and prior authorization criteria, they must comply with New York's step therapy override requirements, appeal timelines, and external review processes.

Key New York Advantages:

  • Step therapy overrides available with proper documentation
  • 72-hour standard decision timelines (24 hours for urgent cases)
  • Binding external appeals through the Department of Financial Services
  • Strong continuity of care protections during plan transitions
Note: These protections apply to most commercial Aetna plans in New York. Self-funded employer plans may have different rules under federal ERISA law.

New York's Step Therapy Override Protections

Under New York Insurance Law Section 4903, Aetna must grant a step therapy override if your physician provides documentation showing:

Medical Exception Criteria:

  • Contraindication: The required drug will likely cause harm or adverse reaction
  • Expected Ineffectiveness: Based on your clinical history, the required drug won't work
  • Prior Treatment Failure: You've already tried the required drug (or similar) and it failed or caused problems
  • Clinical Stability: You're stable on Nourianz and switching would disrupt treatment
  • Best Interest Exception: The required drug would create barriers to adherence or worsen other conditions

Documentation Requirements: Your neurologist must submit supporting rationale specifying which criteria applies, including:

  • Patient identification and diagnosis
  • Specific drugs requested vs. required by plan
  • Clinical evidence of prior failures or contraindications
  • Clear statement if condition is urgent

Timeline Requirements:

  • Standard cases: Decision within 72 hours
  • Urgent cases: Decision within 24 hours if health in serious jeopardy
  • Approval duration: Up to 12 months once approved
From our advocates: We've seen patients successfully obtain step therapy overrides for Nourianz by having their neurologist document that previous adjunct medications like amantadine caused intolerable side effects or failed to adequately control OFF episodes. The key is specific clinical documentation rather than general statements about ineffectiveness.

Appeals Process and Timelines

Internal Appeals with Aetna CVS Health

First Level Appeal:

  • Deadline: 180 days from denial notice
  • Timeline: 30 days for standard; 72 hours for urgent
  • Submit to: Aetna member portal or appeals department
  • Include: Denial letter, clinical notes, medical necessity letter

Expedited Appeals:

  • When to use: If delay would seriously jeopardize health
  • Timeline: 72 hours for decision
  • Requirements: Physician attestation of urgency

Peer-to-Peer Review

Request a peer-to-peer review where your neurologist can speak directly with Aetna's medical director. This often resolves complex cases faster than written appeals.

Script for requesting peer-to-peer: "I'm requesting a peer-to-peer review for my patient's Nourianz prior authorization denial. The patient has Parkinson's disease with inadequately controlled OFF episodes despite optimized levodopa therapy and has failed/cannot tolerate standard adjunct medications."

External Review Through New York DFS

If Aetna denies your internal appeals, New York's external review process provides binding independent review.

When to File:

  • After receiving final adverse determination from Aetna
  • Within 4 months of the final denial
  • For denials based on medical necessity, experimental/investigational status, or formulary exceptions

Required Documents:

  • Completed DFS external appeal application
  • Copy of Aetna's final denial letter
  • All relevant medical records
  • Physician attestation for urgent cases

Timelines:

  • Standard: 30 days for decision
  • Urgent: 72 hours
  • Expedited formulary: 24 hours for urgent drug needs

Cost: $25 per appeal (waived for Medicaid or financial hardship)

Success Rates: New York's external review database shows favorable outcomes for many specialty drug appeals when proper medical documentation is provided.
