Why Michigan State Rules Matter

Michigan's insurance laws provide important protections that work alongside your Blue Cross Blue Shield of Michigan (BCBSM) policy. For expensive rare disease medications like Bylvay, these state rules can be the difference between coverage and denial.

Key Michigan protections include:

  • 127-day external review window after final denial
  • Step therapy exception rights when alternatives fail or are inappropriate
  • Expedited appeals for urgent medical needs (72-hour decisions)
  • Medical necessity standards that insurers must follow

However, these protections only apply to fully-insured plans. If you have employer coverage through a self-funded ERISA plan, federal rules apply instead, though many protections are similar.

Note: BCBS Michigan covers about 67% of commercial plan members in the state, making it the dominant insurer. This guide focuses on their specific processes.

Understanding Turnaround Standards

Michigan law and BCBS policies establish specific timeframes for coverage decisions:

Initial Prior Authorization:

  • Standard requests: 5-7 business days
  • Expedited requests: 24-48 hours (requires provider certification of urgency)

Internal Appeals:

  • Pre-service appeals: 30 days to file, decision within reasonable timeframe
  • Post-service appeals: 60 days to file

External Review (DIFS):

  • Standard: No fixed limit, but handled promptly
  • Expedited: 72 hours maximum
  • Filing deadline: 127 days after final internal denial
Tip: For Bylvay, given its use in progressive liver disease, providers may be able to justify expedited review if pruritus is severe and affecting quality of life significantly.

Step Therapy Protections

Michigan law (MCL 550.1911(3)) provides important protections against inappropriate step therapy requirements. BCBS must grant a step therapy exception if:

  • The step therapy drug hasn't been FDA-approved for your child's specific condition
  • Your provider determines the step therapy protocol is not medically appropriate
  • Your child has already tried and failed the step therapy medication
  • The step therapy drug is contraindicated or likely to cause adverse reactions

Documentation requirements for step therapy exceptions:

  • Physician statement supporting the exception request
  • Medical records showing prior treatment attempts and outcomes
  • Clinical rationale for why the step therapy drug is inappropriate
  • Lab results or other objective measures (within 6 months for new starts)

Decision timeline: BCBS must decide within 72 hours of receiving the physician's supporting statement. For expedited requests with health urgency, decisions must come within 24 hours.

Continuity of Care Rights

If your child is already taking Bylvay and you're switching to BCBS Michigan, you may have continuity of care protections:

  • Transition supplies: Plans often provide temporary coverage while PA is processed
  • Ongoing therapy: If Bylvay was previously approved by another insurer, document this for BCBS
  • Grace periods: Some plans offer 30-90 day continuations for specialty medications

Contact BCBS member services immediately upon enrollment to discuss transition coverage.

External Review & State Appeals

When BCBS denies coverage after internal appeals, Michigan's external review process provides an independent assessment.

Michigan DIFS External Review Process:

  1. Eligibility: Must complete BCBS internal appeals first
  2. Filing: Submit DIFS External Review Request within 127 days
  3. Required documents:
    • Copy of BCBS final denial letter
    • Grounds for appeal
    • Supporting medical documentation
    • For experimental/investigational denials: Treating Provider Certification
  4. Review: Independent medical experts assess medical necessity
  5. Decision: Binding on BCBS if overturned

"Experimental/investigational" Cite FDA approval for PFIC/Alagille syndrome FDA label, clinical guidelines
"Step therapy required" File step therapy exception with prior treatment documentation Records of UDCA/cholestyramine trials and outcomes

"Non-formulary" Request formulary exception with medical necessity justification Comparative effectiveness data, specialist recommendation
"Quantity limit exceeded" Justify weight-based dosing per FDA labeling Current weight, dosing calculation, prescriber attestation

Consider additional help from:

  • Patient advocacy organizations for rare liver diseases
  • Manufacturer patient assistance programs
  • Legal aid societies for insurance disputes
From our advocates: "We've seen families succeed with Bylvay appeals by focusing on the progression of symptoms despite standard treatments. One family documented daily pruritus scores and sleep disruption for several weeks, which helped demonstrate medical necessity when combined with failed UDCA therapy. While every case is different, objective symptom tracking often strengthens appeals."
