The headline for prescribed drugs in 2026 was easy: “Out-of-pocket prices are capped at $2,100.” For hundreds of thousands of seniors, this seemed like a promise that they might by no means pay greater than that quantity for his or her drugs. The truth, nonetheless, is buried within the complicated “phases” and “tiers” of your particular Half D plan.
Whereas the cap is actual, the trail to reaching it—and what counts towards it—is filled with potholes. Insurers have responded to the brand new cap by shifting prices to the entrance of the 12 months and tightening the foundations on which medication qualify.

For years, “Tier 3” medication (most popular manufacturers) often got here with a flat copay, like $45 or $47. In 2026, to handle the monetary threat of the brand new cap, many plans have transformed Tier 3 from a flat copay to a percentage-based coinsurance.
