Qualification pathways

You can qualify through any one of these.

Documentation to bring

• Documentation of prescription drug benefit coverage for weight loss medications
• Documentation of no personal or family history of MTC or MEN 2
• Diagnosis documentation for chronic weight management
• Current weight and BMI documented within the last 30 days
• Documentation of current diet and exercise program participation
• BMI >= 30 kg/m2 or BMI >= 27 kg/m2 with documentation of qualifying comorbidity (hypertension, diabetes, or hyperlipidemia)

• Documentation of failed minimum 6-month trial of semaglutide (Ozempic/Wegovy) with bariatric medicine chart review supporting need to switch; OR documentation of allergy/intolerance/contraindication to semaglutide

Approval and renewal

• Initial approval: 12 months
• Renewal: every 12 months
• To renew, the plan looks for at least 5% weight loss from the starting weight and Patient must have achieved and maintained 5% or greater weight loss after starting tirzepatide (Zepbound). Updated weight and BMI must be recently documented. Initial criteria (prior therapy trials, BMI thresholds, comorbidities, rider requirement) are not re-verified at continuation. Make sure your starting weight and date are in the chart now — renewal is measured against it.

Not covered when

• Personal or family history of medullary thyroid carcinoma (MTC)
• Personal or family history of Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)
• No weight loss prescription drug benefit

Policy note: Adequate trial is defined as a 3-month treatment duration. Intolerance excludes adverse drug reactions that are expected, mild in nature, resolve with continued treatment, and do not require medication discontinuation. The non-GLP-1 step therapy requirement does NOT apply to Medicare Part D patients or Washington Medicare patients (footnote **). The prior semaglutide step therapy requirement also does NOT apply to Medicare Part D patients or Washington Medicare patients. A separate pathway exists for new members entering KP already on the medication for chronic weight management (simplified criteria requiring only benefit verification and diagnosis).
