To the FEHB Blue Cross Blue Shield (Federal Employee Program) Prior Authorization Reviewer,

I am the treating clinician for [Patient name]. I am writing to request prior authorization for Zepbound (tirzepatide) for treatment of Obstructive sleep apnea (Zepbound SURMOUNT-OSA indication) (ICD-10: G47.33).

Clinical justification

FDA approved Zepbound (tirzepatide) for the treatment of moderate-to-severe obstructive sleep apnea in adults with obesity in December 2024, based on the SURMOUNT-OSA trial program. SURMOUNT-OSA enrolled adults with moderate-to-severe OSA (AHI greater than or equal to 15 events per hour) and BMI greater than or equal to 30. At week 52, Zepbound reduced the apnea-hypopnea index by 25 to 29 events per hour versus 5 events per hour for placebo, with approximately 43 to 52 percent of treated patients achieving disease resolution (AHI less than 5 or AHI 5 to 14 with no daytime symptoms). This is the first GLP-1 indication for OSA and is a Medicare-eligible indication unlike pure obesity.

Patient-specific findings

  - [Insert current measurements: weight, height, BMI, blood pressure]
  - [Insert relevant lab values with dates: A1c, lipid panel, kidney function]
  - [Insert documentation of comorbidities with ICD-10]
  - [Insert documentation of prior treatment history, including any prior GLP-1 trials, anti-obesity medication trials or lifestyle intervention]

Criteria met per FEHB Blue Cross Blue Shield (Federal Employee Program) policy

This request meets the criteria set out in Blue Cross and Blue Shield Service Benefit Plan, Federal Employee Program, GLP-1 PA Criteria:

  - OSA diagnosed by polysomnography or home sleep apnea test with AHI greater than or equal to 15 (moderate to severe)
  - BMI greater than or equal to 30
  - Documentation of CPAP intolerance, non-adherence or patient preference (some plans require CPAP failure first; the FDA label does not require it)
  - Sleep medicine specialist involvement if the plan requires it
  - Most recent sleep study report attached

Supporting evidence

The clinical case for Zepbound (tirzepatide) in this indication is supported by the following registration trials and outcomes data:

  - SURMOUNT-OSA Study 1 (Zepbound in OSA patients on PAP therapy)
  - SURMOUNT-OSA Study 2 (Zepbound in OSA patients not on PAP therapy)

Plan-specific note

FEP BCBS covers Wegovy and Zepbound for obesity at BMI greater than or equal to 30 (or 27 with comorbidity) with documented dietary intervention. The FEP formulary is generally more generous than commercial Anthem for anti-obesity drugs because federal coverage mandates are statutorily different. PBM is CVS Caremark.

Requested action

I am requesting prior authorization for Zepbound (tirzepatide) at the [insert starting dose] starting dose, with planned titration per FDA labeling. I am also requesting that this authorization be granted for a continuous 12-month period subject to documented clinical response, per standard formulary practice.

If additional information is required, please contact me directly at [Prescriber phone] or [Prescriber email]. I am available to discuss this case with your medical director if helpful.

Thank you for your attention to this request.

Sincerely,

Attachments:
  - Current vital signs and BMI calculation
  - Most recent relevant labs
  - Documentation of comorbidities
  - Documentation of prior treatment trials
  - Sleep study report (if OSA indication)
  - Cardiac history documentation (if CV indication)

Clinical rationale for this indication

FDA approved Zepbound (tirzepatide) for the treatment of moderate-to-severe obstructive sleep apnea in adults with obesity in December 2024, based on the SURMOUNT-OSA trial program. SURMOUNT-OSA enrolled adults with moderate-to-severe OSA (AHI greater than or equal to 15 events per hour) and BMI greater than or equal to 30. At week 52, Zepbound reduced the apnea-hypopnea index by 25 to 29 events per hour versus 5 events per hour for placebo, with approximately 43 to 52 percent of treated patients achieving disease resolution (AHI less than 5 or AHI 5 to 14 with no daytime symptoms). This is the first GLP-1 indication for OSA and is a Medicare-eligible indication unlike pure obesity.

ICD-10 codes to attach

• G47.33

Criteria checklist (what to attach with the letter)

1. OSA diagnosed by polysomnography or home sleep apnea test with AHI greater than or equal to 15 (moderate to severe)
2. BMI greater than or equal to 30
3. Documentation of CPAP intolerance, non-adherence or patient preference (some plans require CPAP failure first; the FDA label does not require it)
4. Sleep medicine specialist involvement if the plan requires it
5. Most recent sleep study report attached

Supporting trials and evidence

• SURMOUNT-OSA Study 1 (Zepbound in OSA patients on PAP therapy)
• SURMOUNT-OSA Study 2 (Zepbound in OSA patients not on PAP therapy)

The denial reasons to preempt

Most denials of this combination cite one of the reasons below. Address each one in the patient-specific findings section before you send. If the plan denies anyway, the appeal letter cites the same evidence with the denial reason added in the opening paragraph.

• Sleep study is more than three years old
• AHI documented is below 15 (mild OSA, not the SURMOUNT-OSA enrollment threshold)
• Patient has not been counseled on PAP therapy first on plans that require step therapy

If you have not picked a program yet
