CareFirst BlueCross BlueShield prior authorization letter for Obstructive sleep apnea (Zepbound SURMOUNT-OSA indication).
A defensible, plan-specific letter template for Zepbound (tirzepatide). FDA expanded Zepbound's label in December 2024 to include moderate-to-severe obstructive sleep apnea in adults with obesity. This is the first GLP-1 indication for OSA and opens a coverage path under Medicare.
Plan note: CareFirst BCBS covers Wegovy and Zepbound at BMI greater than or equal to 30, or 27 with at least one weight-related comorbidity (T2D, hypertension, dyslipidemia, OSA). Six months of dietary and physical-activity intervention required. CVS Caremark is the PBM for most CareFirst commercial lines. Federal Employee Program members route through the FEHB BCBS policy instead.
CareFirst BlueCross BlueShield contracts pharmacy benefit administration to CVS Caremark, which adjudicates this PA. The criteria below are pulled from the publicly posted PBM clinical policy. Match each item before you send.
- BMI greater than or equal to 30, OR BMI greater than or equal to 27 with at least one weight-related comorbidity (T2D, hypertension, dyslipidemia, OSA)
- Documented six-month lifestyle intervention or prior anti-obesity medication trial
- Step therapy through phentermine or orlistat (or documented contraindication / intolerance)
- Treatment plan including continued lifestyle counseling and 5 percent weight-loss target at 6 months
- Reauthorization requires documented adherence and ≥5 percent weight loss from baseline at 12 months

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 CareFirst BlueCross BlueShield policy This request meets the criteria set out in CareFirst Medical Policy 5.01.32, Anti-Obesity Pharmacotherapy: - 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 CareFirst BCBS covers Wegovy and Zepbound at BMI greater than or equal to 30, or 27 with at least one weight-related comorbidity (T2D, hypertension, dyslipidemia, OSA). Six months of dietary and physical-activity intervention required. CVS Caremark is the PBM for most CareFirst commercial lines. Federal Employee Program members route through the FEHB BCBS policy instead. 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.

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)
- 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 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
