Routine care during qualifying trials must be covered. ACA plans can’t deny coverage for routine patient costs in approved trials for cancer or life-threatening conditions. The experimental item itself is usually paid by the study. Cost: Expect your deductible, then a copay or coinsurance. Ask the plan for a negotiated estimate before care.

Does Original Medicare cover clinical trials?

Medicare covers routine costs in qualifying trials. Office visits and tests are covered; the investigational item is generally not. Cost: Generally 20% of the Medicare-approved amount after the Part B deductible.
