Medicare Part D penalties rank among the most frustrating surprises in retirement because a single missed enrollment window can affect prescription drug costs for years. Many people focus on doctor visits and hospital coverage, then discover much later that drug coverage follows a completely different set of rules.

That surprise often arrives at the pharmacy counter, where a monthly premium suddenly costs more than expected.
