To the Blue Shield of California Prior Authorization Reviewer,

I am the treating clinician for [Patient name]. I am writing to request prior authorization for Wegovy, Zepbound or off-label Mounjaro depending on T2D status for treatment of PCOS with metabolic syndrome (ICD-10: E28.2, E66.9, R73.03).

Clinical justification

PCOS itself is not an FDA-approved indication for any GLP-1 receptor agonist, but PCOS frequently coexists with insulin resistance, prediabetes and obesity, each of which is a qualifying indication. This PA pathway requests coverage under the obesity indication (if BMI greater than or equal to 30 or 27 with comorbidity) or under the T2D indication (if A1c greater than or equal to 6.5 percent). PCOS-specific evidence: a 2023 systematic review in Reproductive Sciences pooled GLP-1 trial data in women with PCOS and found significant improvements in BMI, insulin resistance (HOMA-IR) and androgen levels at 12 to 24 weeks of treatment.

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 Blue Shield of California policy

This request meets the criteria set out in Blue Shield of California Medical Policy, Anti-Obesity Pharmacotherapy:

  - PCOS diagnosis documented with ICD-10 E28.2 (often confirmed by Rotterdam criteria)
  - Documentation of metabolic complications: insulin resistance, prediabetes (A1c 5.7 to 6.4) or T2D (A1c greater than or equal to 6.5)
  - BMI documented (qualifies under obesity pathway if 30 or above, or 27 with comorbidity)
  - Six-month lifestyle intervention documented for the obesity pathway
  - Endocrinology or reproductive endocrinology consult letter (strengthens but not always required)

Supporting evidence

The clinical case for Wegovy, Zepbound or off-label Mounjaro depending on T2D status in this indication is supported by the following registration trials and outcomes data:

  - Jensterle et al. 2014 (liraglutide in PCOS, Endocrine Connections)
  - Frossing et al. 2018 (liraglutide in PCOS, Diabetes Obesity and Metabolism)
  - Pooled meta-analyses of GLP-1 in PCOS (Reproductive Sciences 2023)

Plan-specific note

Blue Shield CA has historically required BMI greater than or equal to 30, documented lifestyle intervention for at least six months and step therapy through phentermine where not contraindicated. Some Blue Shield Promise (Medi-Cal managed care) plans follow Medi-Cal PDL, which excludes GLP-1 for obesity indication entirely as of 2026.

Requested action

I am requesting prior authorization for Wegovy, Zepbound or off-label Mounjaro depending on T2D status 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,

Clinical rationale for this indication

PCOS itself is not an FDA-approved indication for any GLP-1 receptor agonist, but PCOS frequently coexists with insulin resistance, prediabetes and obesity, each of which is a qualifying indication. This PA pathway requests coverage under the obesity indication (if BMI greater than or equal to 30 or 27 with comorbidity) or under the T2D indication (if A1c greater than or equal to 6.5 percent). PCOS-specific evidence: a 2023 systematic review in Reproductive Sciences pooled GLP-1 trial data in women with PCOS and found significant improvements in BMI, insulin resistance (HOMA-IR) and androgen levels at 12 to 24 weeks of treatment.

ICD-10 codes to attach

• E28.2
• E66.9
• R73.03

Criteria checklist (what to attach with the letter)

1. PCOS diagnosis documented with ICD-10 E28.2 (often confirmed by Rotterdam criteria)
2. Documentation of metabolic complications: insulin resistance, prediabetes (A1c 5.7 to 6.4) or T2D (A1c greater than or equal to 6.5)
3. BMI documented (qualifies under obesity pathway if 30 or above, or 27 with comorbidity)
4. Six-month lifestyle intervention documented for the obesity pathway
5. Endocrinology or reproductive endocrinology consult letter (strengthens but not always required)

Supporting trials and evidence

• Jensterle et al. 2014 (liraglutide in PCOS, Endocrine Connections)
• Frossing et al. 2018 (liraglutide in PCOS, Diabetes Obesity and Metabolism)
• Pooled meta-analyses of GLP-1 in PCOS (Reproductive Sciences 2023)

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.

• PA submitted for PCOS alone without coexisting obesity or T2D documentation
• No documentation of insulin resistance or metabolic complications
• Plan requires endocrinology consult and only primary care submitted

If you have not picked a program yet

The PA path is faster when your prescriber is already familiar with your insurance plan and runs the authorization regularly. Programs in our chart that actively run prior authorization for Wegovy, Zepbound or off-label Mounjaro depending on T2D status:

• PlushCare · commercial and Medicare PA experience
• Form Health · obesity-medicine specialty, high PA success rate
• Knownwell · cardiometabolic focus, all major PBMs
• Calibrate · insurance-focused, employer-friendly
