NovoLog is a brand of insulin aspart, human. What agents check before quoting it: how many 2026 Part D plans cover it, on which tier, with what restrictions and copays, by plan type, carrier and state.
In 2026, 5,496 of 5,496 Medicare Part D and Medicare Advantage drug plans (100%) list NovoLog on their formulary, across 328 of 328 formularies. The most common placement is tier 3 (5,110 plans, 93% of those covering it). 0 of the covering plans require prior authorization (0%), 22 step therapy and 616 a quantity limit. Generic insulin aspart, human is on 5,496 of 5,496 plans (100%).
1,700 covering plans charge a flat copay for a 30-day supply at a preferred retail pharmacy after the deductible — median $47, 251 of them $0; 3,796 charge coinsurance instead — median 24% of the drug's cost. Covered insulin is capped at $35 for a month's supply.
NovoLog has a Medicare negotiated price (maximum fair price) of $119 for a 30-day supply, which applies. The negotiated price lowers what the plan pays; the member's copay or coinsurance still follows the plan's tier.

Counts are over every Medicare Advantage drug plan and stand-alone Part D plan in the CMS monthly formulary files, excluding employer plans. A plan counts as covering a drug when any strength or form of it is on the plan’s formulary; the tier, prior authorization, step therapy and quantity limit shown are the most favorable version on that formulary. Copays are for a 30-day supply at a preferred retail pharmacy after the deductible. This is a reference for licensed agents, not a plan recommendation; verify with the plan’s formulary before advising a client. Source: CMS Part D formulary files (release 09/16/2026).
