Prediabetes and the Medicare GLP-1 Bridge
Short answer: Prediabetes is a Tier 3 qualifying condition: combined with a BMI of just 27 or higher, it makes you eligible for Medicare's $50/month GLP-1 Bridge program. Because roughly half of adults over 65 have prediabetes — most without knowing it — this is almost certainly the program's most common eligibility path, and the most overlooked.

Do you have prediabetes without knowing it?
Prediabetes means blood sugar above normal but below the diabetes line — an A1c of roughly 5.7% to 6.4%, or fasting glucose of 100–125 mg/dL. It has no symptoms. If a doctor has ever said your sugar was 'borderline,' 'a little high,' or 'something to watch,' there's a good chance the number is already in your chart.
The test is a routine blood draw Medicare covers. If you haven't had an A1c in the past year, one appointment settles both the diagnosis question and — if your BMI is 27+ — your Bridge eligibility.
The math that surprises people
BMI 27 is about 167 pounds at 5'6", 178 pounds at 5'8", or 188 pounds at 5'10". Add how widespread prediabetes is at Medicare age, and Tier 3 through prediabetes plausibly describes millions of people who assume a weight-loss drug program 'isn't for someone their size.' It's worth two minutes with the calculator below.
One boundary to know: at A1c 6.5% or above, the diagnosis becomes type 2 diabetes — which doesn't end your GLP-1 options but routes you to standard Part D coverage instead of the Bridge, a path with its own (often better) cost rules.

Common questions
What A1c range counts as prediabetes?
Roughly 5.7% to 6.4%. Below 5.7% is normal; 6.5% or above is type 2 diabetes, which routes you to standard Part D GLP-1 coverage instead of the Bridge.
Will Medicare pay for the A1c test?
Medicare covers diabetes screening blood tests for people with risk factors, and A1c testing is routine in annual bloodwork. Ask at your annual wellness visit.
I reversed my prediabetes with diet. Do I still qualify?
Eligibility rests on what your provider documents in the prior authorization. If your current A1c is back in the normal range, discuss with your doctor whether the diagnosis still stands in your chart.
