Quick answer
Only for a few reasons. Under the ACA, an insurer can’t cancel your coverage because you get sick or make an honest mistake on your application. It can end your coverage if you stop paying premiums, commit fraud or intentionally misrepresent important facts, move out of the plan’s service area, or if the insurer stops offering your plan. Canceling for fraud requires at least 30 days’ notice, and you can appeal.
Key takeaways
- Getting sick, pregnant or diagnosed with a costly condition can’t get you dropped.
- Missing premiums is the most common reason people lose coverage.
- Marketplace enrollees with tax credits get a three-month grace period to catch up.
- If your insurer leaves the market, you’ll get notice and a chance to pick a new plan.
- You can appeal a cancellation, including through an independent review.

When an insurer can end your coverage
| Reason | What happens |
|---|---|
| You don’t pay your premiums | Coverage ends after the grace period |
| Fraud or intentional misrepresentation | The insurer can cancel back to the start (rescission), with at least 30 days’ notice |
| You move out of the plan’s service area | You’ll need a new plan; moving opens a special enrollment period |
| The insurer stops selling your plan or leaves the market | You get advance notice and can choose a new plan |
| You lose eligibility for job-based coverage | Coverage ends; you may be offered COBRA |
Insurers can’t cancel coverage because of your health, a new diagnosis or a pregnancy. And an honest mistake on your application isn’t grounds for rescission.
Grace periods for missed payments
- Marketplace plans with tax credits: You get three months to pay what you owe, as long as you paid at least one month’s premium this year. The plan pays claims in the first month; claims in months two and three are held. If you don’t catch up, coverage ends at the end of the first month, and you’re responsible for care after that. See what a subsidy is in health insurance.
- Plans without tax credits: State law sets the grace period, often around 30 days.
- Job-based plans: Premiums usually come out of your paycheck. With COBRA, you generally have 30 days after the due date to pay.
If you’re struggling to pay, lower your costs before you fall behind. Update your income with the marketplace, since a drop in income can raise your tax credit, or switch plans at the next open enrollment. See how to switch health insurance companies.
If your insurer leaves the market
Insurers can stop selling a plan, or leave a state, at the end of a plan year. They must notify you in advance. For 2027, several insurers are leaving marketplaces, including Cigna in all 11 of its states. On HealthCare.gov, you can pick a new plan during open enrollment; if you don’t, you may be matched with a similar plan from another insurer. See the best health insurance companies.
Losing other kinds of coverage
- Job-based coverage ends when you leave a job or no longer qualify. You can usually keep it through COBRA or switch to a marketplace plan.
- Medicaid can end at renewal if you no longer qualify or don’t return paperwork. Starting in 2027, many expansion adults will have to renew every six months and meet work requirements.
Losing coverage is a qualifying life event that lets you pick a new plan; see qualifying events.
How to fight a cancellation
Ask the insurer for the reason in writing, gather proof (like payment records), and file an appeal. A rescission can be appealed, and you can ask for an independent external review. See how to appeal a health insurance claim denial. Your state insurance department can also help.
