Cigna requires prior authorization for Nucala (mepolizumab) in Michigan with specific eosinophil count criteria (≥300 cells/µL) and step therapy requirements. You'll likely need to try benralizumab or dupilumab first unless contraindicated. If denied, Michigan's DIFS external review process gives you 127 days to appeal with independent medical review within 30-60 days.

Submit your PA request through Cigna's provider portal with complete clinical justification.

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn Required Documentation
Step therapy not completed Provide evidence of benralizumab/dupilumab trial failure or contraindication Prescription records, adverse event documentation, clinical notes
Insufficient eosinophil count Submit recent lab showing ≥300 cells/µL OR historical count before anti-IL5 therapy Laboratory reports within 6 weeks
Inadequate ICS adherence Document high-dose inhaled corticosteroid use with refill history Pharmacy records, medication reconciliation, provider attestation
Not medically necessary Cite clinical guidelines and demonstrate severe, uncontrolled disease ACT scores, exacerbation records, FDA labeling
Off-label use Provide peer-reviewed evidence and clinical rationale Published studies, specialty society guidelines
From our advocates: We've seen Michigan patients succeed by including a detailed timeline showing exactly when each biologic was tried, why it failed, and how quickly symptoms returned. Cigna's medical reviewers appreciate this chronological approach to demonstrating medical necessity.

Frequently Asked Questions

Q: How long does Cigna prior authorization take in Michigan? A: Standard requests must be processed within 15 calendar days. Expedited requests require a decision within 72 hours. If Cigna doesn't respond within these timeframes, the authorization is automatically approved.

Q: What if Nucala isn't on Cigna's formulary? A: You can request a formulary exception through Cigna's standard PA process. Include clinical justification for why preferred alternatives aren't suitable and provide supporting medical literature.

Q: Can I appeal if I live in Michigan but have an out-of-state Cigna plan? A: Michigan's external review rights apply to Michigan residents regardless of where their plan is domiciled. However, verify with DIFS as some federal plans may have different procedures.

Q: Do I need to retry failed biologics if I move to Michigan? A: No. If you've tried and failed benralizumab or dupilumab within the past 365 days, this should satisfy Cigna's step therapy requirements. Provide complete documentation of the previous trial.

Q: What's the difference between medical necessity and step therapy denials? A: Step therapy denials require trying preferred medications first. Medical necessity denials question whether the treatment is appropriate for your condition. Both can be appealed with proper documentation.

Q: Can my doctor request a peer-to-peer review? A: Yes. Your physician can request to speak directly with Cigna's medical director to discuss your case. This often happens before formal denials and can resolve coverage issues quickly.
