ACA and short-term medical plans cover you before Medicare starts.

If you need coverage before you’re 65, ACA and short-term medical plans may help.

Do you need coverage before age 65?

Retiring early, losing a job, or aging off a family member’s plan can leave you without health insurance before you become eligible for Medicare. Depending on your situation, you may be able to fill the gap with an ACA Marketplace plan, a short-term medical plan, or other options. Each works differently, so it helps to understand the tradeoffs before you choose.

What can cause a gap in health insurance?

Common reasons include:

Before you look at individual plans, check these possibilities:

Enrolling in ACA plans.

The Affordable Care Act (ACA), also called Obamacare, lets you buy coverage through a Marketplace. Because these plans can’t turn anyone away, you can only enroll during specific windows:

If you miss open enrollment and don’t have a qualifying life event, you generally can’t enroll in an ACA plan until the next open enrollment period.

Other things to know about ACA plans.

ACA plans must cover a set of essential health benefits, including maternity care, mental health services, and prescription drugs. They can’t deny you coverage or charge you more because of a pre-existing condition. Many people also qualify for premium tax credits that lower their monthly cost, depending on household income. Because the enhanced credits that were available in recent years expired at the end of 2025, it’s worth having your options reviewed even if you looked in the past.

Short-term medical plans.

Short-term medical plans are designed to bridge brief gaps in coverage. They generally have lower premiums than ACA plans, you can often enroll at any time, and coverage can sometimes start within days. How long a plan can last, and whether you can renew or buy another, depends on federal and state rules that have changed several times in recent years and vary widely.

Availability also depends on where you live. In some states, including New Jersey and New York, short-term plans generally aren’t available at all. In others, such as Maryland and Pennsylvania, duration is limited to just a few months.

Limitations of short-term medical plans.

Short-term plans aren’t required to follow ACA rules, so they come with real tradeoffs:

Read the benefits summary closely before you enroll, and make sure you understand what isn’t covered.

Planning for your transition to Medicare.

Your Initial Enrollment Period for Medicare begins three months before the month you turn 65 and lasts seven months. Coordinating the end of your current coverage with the start of Medicare helps you avoid gaps and late enrollment penalties. If you have an ACA Marketplace plan, you should generally end it once your Medicare coverage begins, since Marketplace subsidies typically stop when you become eligible for premium-free Medicare Part A.
