Why Michigan State Rules Matter

Michigan's healthcare landscape provides strong consumer protections that work alongside Aetna CVS Health's policies. With approximately 67% of commercial coverage dominated by Blue Cross Blue Shield of Michigan, other carriers like Aetna must comply with Michigan's Patient's Right to Independent Review Act (PRIRA), which governs step therapy overrides and external appeals.

For hemophilia and von Willebrand disease patients, Michigan law requires insurers to grant step therapy exceptions when preferred drugs pose serious health risks or when patients are stable on their current therapy. This protection is crucial for Humate-P, where switching between factor concentrates can affect bleeding control.

Line-of-Business Nuances

  • Commercial Plans: Follow standard Aetna policies with Michigan appeal timelines
  • Aetna Better Health (Medicaid): Specific formulary policies for hemophilia treatments
  • Medicare Advantage: Part B coverage for buy-and-bill administration

Step Therapy Protections in Michigan

Michigan's PRIRA provides robust protections against inappropriate step therapy requirements for bleeding disorders. Under MCL 550.1911, insurers must grant overrides when:

  • Patient is stable on the requested drug and alternatives are expected to be ineffective
  • Preferred step therapy drugs are contraindicated due to patient history
  • Lower likelihood of success based on genetic profile or disease severity
  • Serious health risks from step therapy versus requested therapy

Documentation for Step Therapy Override

When requesting an override, include:

  • Prior treatment timeline: Dates, dosages, outcomes of previous therapies
  • Clinical rationale: Why step therapy fails (e.g., prior treatment complications, hemolysis risks)
  • Contraindication evidence: Medical reasons why preferred agents are inappropriate
  • Bleeding history: Episode frequency, severity, and impact on quality of life
Tip: For hemophilia patients who've tried other factor concentrates in different states, document those experiences thoroughly. Michigan recognizes out-of-state treatment history for step therapy exceptions.

Continuity of Care Safeguards

Michigan provides continuity of care protections for specialty medications during plan transitions. For hemophilia treatment, these safeguards include:

Grace Periods by Plan Type

Plan Type Grace Period Coverage Details
MI Health Link 90 days 30-day initial supply, extendable for complex conditions
Blue Cross Complete Up to 90 days No prior auth needed for transition supply
Commercial Plans 60 days Extendable for specialty therapy continuity

Requesting Continuity Coverage

  1. Contact your new plan's member services within 30 days of enrollment
  2. Request single-case agreement for out-of-network hemophilia center (if needed)
  3. Submit continuity of care form with current treatment documentation
  4. Work with CVS Specialty to coordinate seamless medication transfer

Medical Necessity Letter Scripts

For Hemophilia A

"Patient [Name] has severe hemophilia A (ICD-10: D66) with Factor VIII activity <1%. Current bleeding frequency is [X] episodes per month despite prophylaxis with [prior factor]. Humate-P is medically necessary due to [specific clinical rationale: inadequate response to recombinant factors, development of inhibitors, etc.]. Delay in therapy would seriously jeopardize patient health due to imminent bleeding risk and exhaustion of current factor supply. This recommendation aligns with [World Federation of Hemophilia/National Hemophilia Foundation] guidelines for severe hemophilia management."

For von Willebrand Disease

"Patient [Name] has Type [1/2A/2B/2M/2N/3] von Willebrand disease (ICD-10: D68.0) confirmed by VWF antigen [value], ristocetin cofactor [value], and Factor VIII activity [value]. Desmopressin trial on [date] showed [insufficient response/contraindicated due to cardiovascular risk/hyponatremia]. Humate-P provides both VWF and Factor VIII replacement essential for [surgical prophylaxis/bleeding treatment]. Alternative treatments are inappropriate due to [patient-specific factors]."

Common Denial Reasons & Solutions

Denial Reason Solution Strategy Required Documentation

From our advocates: "We've seen patients successfully appeal Humate-P denials by emphasizing the unique dual-factor replacement needed for certain VWD types. One Michigan patient's appeal was approved within 48 hours after their hematologist clearly documented why single-factor products were inadequate for their Type 2B VWD with severe Factor VIII deficiency. The key was showing that Humate-P's specific VWF/FVIII ratio matched their laboratory-confirmed deficiency pattern."
