Semglee Medicare Coverage & Out-of-Pocket Cost
Semglee is covered under Medicare Part D, with the program paying an average of $139 per prescription fill. Semglee typically falls on Tier 2 (preferred brand) of standard Part D formularies. Typical copay: $25-$50 per fill on most Medicare Part D plans.
Your actual out-of-pocket cost depends on three factors: (1) formulary tier — your plan's specific placement; (2) deductible status — most plans require you to meet up to a $590 deductible (2025) before copays kick in; (3) coverage phase — initial coverage, then the donut hole was eliminated in 2025, replaced by a hard $2,000 annual out-of-pocket cap under the Inflation Reduction Act. Once you hit $2,000 in true out-of-pocket spending, the rest of your Part D drugs are free for the year.
Because generic Insulin Glargine-yfgn is available, the single biggest savings move is asking your pharmacist about generic substitution. Generics typically sit on Tier 1 with copays under $10, vs Tier 2-3 placement for brand-name Semglee. Most states allow automatic substitution unless your prescriber writes "dispense as written."
For cash-pay or commercial insurance scenarios, compare prices using GoodRx, SingleCare, or Cost Plus Drugs before filling — discount-program prices sometimes beat Part D copays for lower-cost generics.
