The short answer
One of the most overlooked costs on a Medicare Advantage plan is the hospital copay. Many plans charge a per-day copay for inpatient hospital stays — often for the first several days of a stay — which can add up to a substantial bill even on a plan with a $0 premium. It's a cost people don't model because they focus on the premium.
So the low premium is real, but a hospital stay is exactly where a $0 plan shows its teeth. Knowing your plan's inpatient copay structure ahead of time matters.
How per-day copays add up
A typical structure charges a set copay for each of the first several days of an inpatient stay, then $0 for the remaining days, all counting toward your annual out-of-pocket maximum. A single surgery-and-recovery stay can therefore run over a thousand dollars in copays, and a second admission later in the year adds more until you hit the cap.
This is the mechanism behind why $0-premium plans can be expensive in a bad year. Our guide to the hidden costs of $0-premium Advantage plans breaks down the full picture.
How to protect against it
First, know your plan's inpatient copay before you enroll, and factor it into the comparison rather than looking at premium alone. Second, consider whether supplemental coverage makes sense: a hospital indemnity plan pays you a fixed cash amount per day in the hospital, which can offset those per-day copays.
Our overview of hospital indemnity insurance explains how that cash benefit works alongside a Medicare Advantage plan to cushion a hospital stay.
