Understanding the Denial

When Humana denies Opsumit (macitentan) coverage, your denial letter will specify the reason. Humana is removing Opsumit from many Medicare formularies in 2025, making appeals more challenging but not impossible.

Common denial codes include:

  • Non-formulary: Drug not on your plan's covered list
  • Prior authorization required: Missing clinical documentation
  • Step therapy: Must try preferred alternatives first
  • Quantity limits: Prescribed amount exceeds plan limits
  • REMS non-compliance: Missing pregnancy testing documentation
Tip: Your denial letter includes specific appeal deadlines and submission instructions. Don't discard it—you'll need these details for your appeal.

REMS Requirements

Opsumit has strict REMS requirements due to severe birth defect risks. Your prescriber must:

  • Enroll in the Opsumit REMS program
  • Document negative pregnancy tests before each prescription
  • Provide monthly pregnancy test results for ongoing therapy
  • Counsel patients on contraception requirements

First-Level Appeal Process

Timeline and Submission

You have 65 calendar days from your denial notice to file an appeal. Humana must respond within:

  • 30 days for pre-service appeals (treatments not yet received)
  • 60 days for post-service appeals (treatments already provided)
  • 72 hours for expedited appeals (urgent medical needs)

How to Submit Your Appeal

Online: Use Humana's member portal for fastest processing

Mail: Send to the address on your denial letter with all supporting documents

Phone: Call the number on your member ID card for urgent situations

Note: Keep copies of all submissions and track your deadlines carefully. Missing the 65-day window typically forfeits your appeal rights.

Peer-to-Peer Review Strategy

If your initial appeal is denied, request a peer-to-peer review with a Humana medical director. This conversation can be pivotal in overturning denials.

Scheduling the Call

  • Contact the number provided in your denial letter
  • Request to speak with a medical director familiar with PAH
  • Prepare for a 15-30 minute clinical discussion

Preparation Checklist

Before the call, have ready:

  • Complete patient chart with diagnostic test results
  • List of previous treatments and specific failure reasons
  • Current functional status and symptoms
  • REMS compliance documentation
  • Relevant clinical guidelines or studies

Key Talking Points

  1. Emphasize disease severity: "This patient has advanced PAH with WHO functional class [X] symptoms significantly impacting quality of life"
  2. Document treatment failures: "Previous therapy with [drug] failed due to [specific adverse event/lack of efficacy] after [duration] of treatment"
  3. Cite medical necessity: "Opsumit is the appropriate next-line therapy per [guideline] recommendations for patients who have failed [previous treatments]"
  4. Address safety: "Patient meets all REMS requirements with documented negative pregnancy testing"

External Review in Florida

If Humana upholds their denial after internal appeals, Florida residents can request an independent external review through the Department of Financial Services.

Eligibility Requirements

  • You must complete Humana's internal appeal process first
  • The denial must involve medical necessity, experimental/investigational treatment, or similar coverage disputes
  • You have 4 months from the final denial to request external review

How to Request External Review

  1. Contact Florida Department of Financial Services Division of Consumer Services
  2. Complete the external review application
  3. Submit all denial letters and appeal documentation
  4. Pay no fee—external review is free to consumers

The external reviewer's decision is binding on Humana if they overturn the denial.

Common Denial Reasons & Solutions

Denial Reason Solution Strategy
Non-formulary Request formulary exception with medical necessity documentation
Missing REMS documentation Submit pregnancy test results and REMS enrollment confirmation
Insufficient PAH documentation Provide complete right heart catheterization report with hemodynamics
Step therapy not met Document contraindications or failures with preferred alternatives
Quantity limits exceeded Justify dosing based on FDA labeling and clinical response
Off-label use Cite FDA labeling for approved PAH indication

From our advocates: "We've seen success when patients work closely with their PAH specialist to document every aspect of their treatment history. One patient's appeal was approved after their doctor provided detailed notes showing why three previous medications failed and how Opsumit specifically addressed their clinical needs. The key was thorough documentation and persistence through the peer-to-peer process."

FAQ

How long does Humana prior authorization take in Florida? Standard prior authorization decisions are made within 30 days for pre-service requests. Expedited reviews for urgent medical needs are completed within 72 hours.

What if Opsumit is completely non-formulary on my plan? You can request a formulary exception with medical necessity documentation. This process follows the same timeline as standard appeals but requires stronger clinical justification.

Can I request an expedited appeal for Opsumit? Yes, if delaying treatment could seriously jeopardize your health or ability to function. Your prescriber must support the urgency request with clinical documentation.

Does step therapy apply if I previously failed medications in another state? Yes, documented treatment failures from other states should be accepted. Provide complete medical records showing previous therapies and failure reasons.

What happens if my external review is denied? External review decisions are final for the specific request, but you may be able to appeal again if your clinical condition changes or new evidence becomes available.

How much does Opsumit cost without insurance? Opsumit typically costs over $10,000 per month without insurance. Manufacturer assistance programs and foundation grants can significantly reduce out-of-pocket costs for eligible patients.
