Mounjaro for Type 2 Diabetes

What Wellmark requires, by plan type. Open this indication on its own page →

Employer / Commercial Insurance

Covered (preferred drug)

What you need to qualify

  • A1C of 6.5% or higher
  • Diagnosis documented with a code
  • Lab results confirming eligibility

Qualification pathways

You can qualify through any one of these.

Auto-adjudication via claims history

All of:

  • ICD-10 diagnosis code for type 2 diabetes mellitus present in member's medical claims history

Prior authorization — confirmed T2DM diagnosis

Plus any one of:

  • History of A1C >= 6.5%
  • History of 2-hour plasma glucose >= 200 mg/dL during OGTT
  • History of symptoms of hyperglycemia (polyuria, polydipsia, polyphagia) or hyperglycemic crisis AND random plasma glucose >= 200 mg/dL
  • History of fasting plasma glucose (FPG) >= 126 mg/dL

Documentation to bring

  • Chart notes or medical record documentation supporting a diagnosis of type 2 diabetes mellitus (A1C > 6.5%, 2-hour plasma glucose >= 200 mg/dL during OGTT, symptoms of hyperglycemia with random plasma glucose >= 200 mg/dL, or fasting plasma glucose >= 126 mg/dL)

Quantity limits

  • all strengths — 4 pens/28 days

Approval and renewal

  • Initial approval: 12 months

Not covered when

  • Diabetic ketoacidosis
  • Not a substitute for insulin
  • Weight reduction/management use is a standard exclusion for most benefits
  • Type 1 diabetes

Policy note: Mounjaro is listed as a preferred product. The policy uses a screen-out logic: if an ICD-10 code for T2DM is present in claims history, the drug is paid without PA. PA is only triggered when the T2DM ICD-10 code is absent from claims history. The policy explicitly states that drugs used for weight reduction/management, including antidiabetic drugs used off-label, are a standard exclusion for most benefits. Mounjaro has not been studied in combination with short-acting, medium-acting, or dual formulation insulins.
