Peer-to-Peer Review Scripts

For Clinic Staff Requesting Peer-to-Peer

"Hello, this is [Name] from Dr. [Provider]'s office. We have a patient with hereditary angioedema whose Takhzyro prior authorization was denied. Dr. [Provider] would like to request a peer-to-peer review with your medical director to discuss the clinical necessity. The patient ID is [number] and the denial reference is [number]. When can we schedule this call?"

For Prescriber During Peer-to-Peer

Opening: "Thank you for taking this call. I'm requesting Takhzyro for a patient with confirmed Type [I/II] hereditary angioedema who is experiencing [X] attacks per month despite on-demand therapy."

Key points to cover:

  • Confirmed HAE diagnosis with specific lab values
  • Attack frequency and severity (include any laryngeal episodes)
  • Prior prophylaxis failures with specific reasons
  • Risk stratification and quality of life impact
  • Why Takhzyro is the most appropriate option

Closing: "Given the unpredictable and potentially life-threatening nature of HAE attacks, prophylactic therapy with Takhzyro is medically necessary to prevent serious morbidity."

Pennsylvania External Review Success

Pennsylvania launched its Independent External Review Program in January 2024, providing a powerful option for commercial insurance denials (note: this doesn't apply to Medicare plans like Humana Medicare Advantage).

However, for Pennsylvania residents with commercial Humana plans, the state's external review offers significant hope:

2024 Success Rates

  • 259 Pennsylvanians successfully appealed denied claims
  • 50.1% overturn rate for external reviews
  • 45-day timeline for standard reviews
  • 72-hour timeline for expedited reviews

How Pennsylvania's Process Works

After exhausting Humana's internal appeals:

  1. Obtain Final Adverse Benefit Determination letter
  2. Submit external review request within 4 months
  3. Independent Review Organization evaluates case
  4. If overturned, Humana must provide coverage immediately

Access Pennsylvania's external review at pa.gov or call the Insurance Department at 1-877-881-6388.

Note: This applies only to commercial Humana plans, not Medicare Advantage. Medicare members use the federal appeals process described above.

FAQ

Q: How long does Humana's prior authorization process take in Pennsylvania? A: Standard PA decisions are made within 7 calendar days. Expedited requests (when delay could jeopardize health) are decided within 72 hours.

Q: What if Takhzyro is not on my Humana formulary? A: Request a formulary exception with an enhanced medical necessity letter explaining why covered alternatives are inappropriate. Include documentation of failed step therapy if required.

Q: Can my doctor call Humana directly to discuss my case? A: Yes. Your prescriber can request a peer-to-peer review with a Humana medical director to discuss clinical necessity before or during the appeals process.

Q: What happens if both internal appeals are denied? A: Medicare Part D members can proceed to an Administrative Law Judge hearing if the amount in controversy exceeds $180 (2024 threshold). Commercial plan members may use Pennsylvania's external review.

Q: Do I need to see a specialist for Takhzyro approval? A: While not always required, having an allergist/immunologist prescribe and support your case significantly strengthens PA and appeal success rates.

Q: How do I prove my attack frequency meets Humana's requirements? A: Maintain a detailed attack diary for several months showing dates, locations, severity, and treatments used. Include any ED visits or hospitalizations. Most policies require ≥1 attack per 4 weeks.
