Health Insurance for Immigrant & Visiting Parents (2026)

How the 5-Year Medicare Rule Works for Green Card Parents

A lawful permanent resident generally must satisfy a 5-year U.S. residence requirement before Medicare Part A and Part B become available on the basis of lawful permanent resident status. This is different from the separate Medicaid five-year waiting rule and should not be described as the same statutory program.

The five-year rule does not mean that a parent receives free Medicare automatically after five years. Medicare eligibility also depends on age or another qualifying basis, lawful residence, work history where relevant, and enrollment rules. A parent who lacks enough work quarters may be able to purchase Part A instead of receiving it premium-free.

Medicare Part A Buy-In: 2026 Costs

In 2026, Medicare Part A is premium-free for most people because they or their spouse paid Medicare taxes long enough, generally at least 10 years. If a person does not qualify for premium-free Part A, they may be able to buy it after meeting the applicable eligibility requirements.

• Fewer than 30 quarters: $565 per month in 2026.
• 30–39 quarters: $311 per month in 2026.
• 40 or more quarters: Part A is generally premium-free.

These are Part A premiums only. A person who buys Part A must also enroll in Part B and pay the applicable Part B premium.

Medicare Part B and Part D

Medicare Part B covers physician and outpatient medical services and has its own monthly premium. The standard Part B premium is $202.90 per month in 2026. Some beneficiaries pay more because of income-related adjustments.

Part D provides prescription-drug coverage through Medicare-approved private plans. Part D premiums and covered drugs vary by plan and location, so there is no single nationwide Part D premium that should be added to a fixed Medicare monthly total.

ACA Marketplace Coverage During the Medicare Waiting Period

Lawful permanent residents are generally among the immigration statuses that may qualify for Marketplace coverage. During the period before Medicare eligibility, an eligible parent can apply through HealthCare.gov and have the Marketplace determine eligibility for premium tax credits and other savings based on the current rules, household information, income, and other factors.

Marketplace savings are not a fixed percentage for every immigrant parent. The actual premium depends on the plan, location, age, household income, household size, and eligibility for financial assistance.

What Happens When the Parent Becomes Medicare-Eligible?

Once a parent becomes eligible for Medicare, the family should compare the Medicare options rather than automatically keeping a Marketplace plan. Medicare.gov states that Marketplace coverage is not a substitute for Medicare once the person is eligible and that Marketplace financial assistance can be affected when Medicare eligibility begins.

The parent may choose Original Medicare with Part A and Part B and may add Part D and supplemental coverage, or may choose a Medicare Advantage plan when eligible. Plan availability and costs vary by location.

Medicare Enrollment and Late Penalties

Medicare enrollment is not simply automatic for every Green Card parent. Most people first become eligible around age 65 and have a seven-month Initial Enrollment Period. The correct enrollment timing depends on the person's circumstances and existing coverage.

Delaying Part B without qualifying coverage can result in a late-enrollment penalty and a coverage gap. People who must pay a premium for Part A can also face a Part A late-enrollment penalty. Parents should check their exact enrollment period with Medicare or Social Security.

Medicaid and the Five-Year Waiting Period

Medicaid is separate from Medicare and has its own federal and state eligibility rules. Many qualified noncitizens are subject to a five-year waiting period before Medicaid and CHIP eligibility, although exceptions and state-specific rules apply. A parent should therefore check the Medicaid rules in the state where they live rather than treating the Medicare five-year rule as the Medicaid rule.

Medicaid eligibility and public-charge treatment are also separate questions. Under the current DHS public-charge framework, Medicaid generally is not counted except for qualifying long-term institutionalization at government expense.

Health Insurance for Parents Visiting on B-1/B-2

A temporary visitor should not assume that Medicare will cover them. Medicare eligibility is based on separate federal eligibility and lawful-residence rules. Visitor medical insurance is a different private-insurance product designed for temporary travel and should be evaluated based on the policy's deductible, coinsurance, exclusions, pre-existing-condition rules, coverage limits, and provider network.

HealthCare.gov eligibility is status-specific and can change with federal policy. Therefore, a visitor should check the current Marketplace application rather than relying on a blanket statement that every B-1/B-2 traveler is automatically eligible or automatically ineligible.

Practical Coverage Timeline

1. Before Green Card residence reaches five years: Check Marketplace and other private coverage options and determine whether Medicaid is available under the parent's state-specific rules.
2. After the Medicare residence requirement: Check Medicare eligibility and determine whether Part A is premium-free or must be purchased.
3. If Part A must be purchased: Budget for the 2026 $311 or $565 Part A premium plus the applicable Part B premium.
4. For prescriptions: Compare Part D or other qualifying drug coverage separately.
5. When Medicare eligibility begins: Review enrollment deadlines and avoid an unnecessary Marketplace/Medicare overlap.
6. For temporary visitors: Compare visitor medical insurance instead of assuming Medicare coverage.
