Quick answer
Yes. Under the ACA, health insurers can’t turn you down, charge you more or exclude cancer care because you have or had cancer. You can buy a marketplace plan during open enrollment or after a qualifying life event, get coverage through a job, or qualify for Medicaid or Medicare. Avoid short-term and other non-ACA plans, which can exclude cancer that started before you enrolled.
Key takeaways
- ACA plans must cover people with cancer on the same terms as everyone else.
- You generally need open enrollment or a qualifying event to buy a marketplace plan.
- Medicaid accepts applications any time, and many states cover women diagnosed through the federal breast and cervical cancer screening program.
- After 24 months of Social Security disability benefits, you qualify for Medicare.
- Compare out-of-pocket maximums, networks and drug lists, not just premiums.

Your options
| Option | What to know |
|---|---|
| Job-based coverage | Must cover pre-existing conditions; losing it opens a special enrollment period |
| Marketplace plan | Open enrollment each fall, or a special enrollment period after a qualifying event |
| COBRA | Keep your current plan and doctors after leaving a job, usually for 18 months |
| Medicaid | Based on income; you can apply any time |
| Medicare | At 65, or after 24 months of disability benefits |
What to look for in a plan
- In-network cancer care. Check that your oncologist, hospital and infusion center are in the network; out-of-network care can be costly, see what to do about out-of-network costs.
- Out-of-pocket maximum. Cancer care often reaches it, so a lower limit can matter more than a lower premium. Compare plan levels.
- Drug coverage. Look up your cancer drugs on each plan’s list.
- Deductible and copays. See what a deductible is and do copays count toward your deductible.
Buying outside the marketplace follows the same rules, but you can’t get a tax credit; see how to buy health insurance outside the ACA exchanges. For more help, see comparing health insurance and getting health insurance with pre-existing conditions.
What cancer coverage includes
ACA plans cover surgery, chemotherapy, radiation, hospital stays, prescriptions, lab work and imaging, plus routine costs if you join an approved clinical trial. See does Obamacare cover cancer treatment.
If a claim is denied
Plans may deny treatments as not medically necessary or require prior approval. Ask your oncologist to document why you need the treatment, and appeal; see how to appeal a health insurance claim denial.

Frequently asked questions
Can I be denied health insurance because I have cancer?
Not for ACA-compliant coverage. Insurers can’t deny you or charge more because of cancer.
Can I get insurance right after a cancer diagnosis?
If you’re in open enrollment or have a qualifying life event, yes. Otherwise, check Medicaid, which accepts applications all year.
Does life insurance or supplemental cancer insurance replace health insurance?
No. Cancer or critical illness policies pay cash benefits and can help with extra costs, but they don’t replace comprehensive health coverage.
