BMI 30: which tier am I in?
Published by GLP-1 Coverage Guide · Updated · No clinician review is credited for this page.
Short answer: A BMI of 30 to 34.9 qualifies you for Medicare's $50/month GLP-1 Bridge with any one of seven conditions: the Tier 2 set (chronic kidney disease stage 3a+, heart failure with preserved ejection fraction (HFpEF), or uncontrolled high blood pressure) or the Tier 3 set (prediabetes, prior heart attack or stroke, or symptomatic PAD), since Tier 3's threshold of 27 includes you.

Use BMI when GLP-1 therapy started
CMS uses BMI at the initiation of GLP-1 therapy, including treatment that began before Medicare enrollment or July 1, 2026. If you have already lost weight on treatment, ask your prescriber to document the starting criteria from your medical records. A lower BMI today does not replace the starting BMI.
This calculator gives an estimate, not a coverage decision. It rounds the estimate to one decimal, to match the one-decimal BMI ranges on the CMS prior-authorization form (27 to 29.9, 30 to 34.9, 35 to 39.9), and uses that same number for the thresholds; your prescriber must attest to the documented criteria.
Seven conditions to check at BMI 30
BMI 30 is about 186 lbs at 5'6", 197 lbs at 5'8", or 209 lbs at 5'10". At this range you have the widest set of qualifying paths in the whole program: CKD stage 3a or higher, heart failure with preserved ejection fraction (HFpEF), systolic above 140 or diastolic above 90 despite two antihypertensives, prediabetes, a previous heart attack or stroke, or symptomatic peripheral artery disease.
Practical implication: at BMI 30+, one ordinary lab panel (A1c and kidney-function tests) can inform your clinician’s assessment, but a single laboratory result does not by itself establish a diagnosis or complete eligibility.
BMI at the start of GLP-1 therapy
Already taking a GLP-1? Use your height and weight when therapy first started. CMS accepts qualifying starting criteria from before Medicare enrollment or July 2026. If starting therapy now, use pre-treatment measurements. Ask your prescriber for records if you do not know.

Common questions
Can I qualify at BMI 32 with no other conditions?
No — BMI alone qualifies only at 35+. Between 30 and 34.9 you need one of the seven qualifying conditions, though several (like prediabetes and early CKD) are common and frequently undiagnosed.
Which qualifying condition is most common?
This guide does not establish the most common diagnosis among current Bridge users. Your prescriber can confirm whether any published condition applies to you.
