Free cancer screenings
ACA plans cover screenings recommended by the U.S. Preventive Services Task Force at no cost when you use an in-network provider:

Protections if you have cancer
- Pre-existing conditions. Insurers can’t deny you, charge you more or exclude cancer care because of your diagnosis. See getting health insurance with pre-existing conditions.
- No dollar caps. Plans can’t set lifetime or yearly dollar limits on essential benefits.
- Out-of-pocket limits. For 2026, you pay no more than $10,600 for one person ($21,200 for a family) for covered in-network care; the limit rises to $12,000 in 2027.
- Clinical trials. Plans must cover routine patient costs, like doctor visits and tests, if you join an approved clinical trial.
- Appeals. If a treatment is denied, you can appeal and ask for an independent review.
Help paying for coverage
- Premium tax credits lower marketplace premiums if your household income is between 100% and 400% of the poverty level.
- Cost-sharing reductions lower deductibles on silver plans if your income is under 250% of the poverty level. With cancer’s high costs, a lower out-of-pocket limit can matter more than the premium.
- Medicaid covers adults with incomes up to 138% of the poverty level in 41 states including DC. Many states also cover women diagnosed through the federal breast and cervical cancer screening program.
- Medicare covers people 65 and older, and younger people after 24 months of disability benefits. See who is eligible for Medicare.
Plans that don’t protect you
Short-term plans, fixed indemnity plans and health care sharing ministries aren’t ACA coverage. They can refuse to cover cancer that started before you enrolled, cap what they pay or cancel coverage. If you’re being treated for cancer, stick with ACA-compliant coverage.
