Yes, you can lose Medicare coverage for reasons like not paying premiums, moving outside a plan's service area (for Medicare Advantage/Part D), providing false info, fraud, or if your plan ends; however, Original Medicare (Part A & B) is generally lifelong unless you voluntarily drop it or lose eligibility (e.g., stop disability benefits), with special enrollment periods often available to get coverage back, notes Medicare.gov and Healthline.
Medicare Part B and Part D Termination
Termination of Medicare Part B can occur if you fail to pay premiums or if you become ineligible due to specific circumstances, such as moving out of the service area. For Medicare Part D, coverage can end if you do not maintain your enrollment or if you decide to cancel.
Your Medicare benefits will be terminated if you do not pay your Part B premium. You will usually receive two notices when you fail to pay your premium. You will be sent a Delinquent Notice if you do not pay your premium by the deadline specified on the second notice.
Medicare termination for non-payment can occur if premiums are missed, even if bills stop arriving. Check your payment history on Medicare.gov and contact Social Security promptly to verify coverage status. If terminated, you may request reinstatement or enroll during a Special Enrollment Period.
If you have Medicare, losing your health coverage is still possible. You can lose Medicare coverage through your actions or for reasons outside of your control, such as an insurance provider deciding to discontinue a plan.
Medicare Parts A and B, or Original Medicare, will only drop you if you don't pay your premiums. However, as long as you've paid 40 quarters (10 years of work) into the Medicare tax system, Medicare Part A is completely free.
Factors like your age, if you're still working, and when you get retirement or disability benefits from Social Security, all impact when and how you sign up for Medicare.
Gray Letter: This notice informs people that they no longer automatically qualify for Extra Help and encourages them to reapply. Orange Letter: This notice informs people with Medicare who automatically qualify for Extra Help that their copayment level will change.
Eligibility Issues: Denials can occur due to discrepancies in income, residency, or documentation, leading to questions about eligibility. Prior Authorization: Some treatments require prior authorization, and failure to obtain this or administrative errors can lead to denials.
Physicians may either agree to be a participating provider or non-participating provider. Providers who do not want to enroll in Medicare or receive Medicare payments are required to sign an “opt out” agreement with their patients.
Generally, you're first eligible to sign up for Part A and Part B starting 3 months before you turn 65 and ending 3 months after the month you turn 65. (You may be eligible for Medicare earlier, if you get disability benefits from Social Security or the Railroad Retirement Board.)
Most exclusions have a specific term length, often 5 years. At the end of your OIG exclusion term, you MUST apply for reinstatement and receive an authorized notice from the OIG that your request was granted. Only then will you be able to participate in all federal healthcare programs (Medicare and Medicaid).
You cannot make too much money to qualify for Medicare. Eligibility is based on age or disability status, not income. That said, higher earnings can trigger income-based surcharges on premiums, particularly for Part B and Part D coverage.
Here are some of the biggest Medicare mistakes to avoid:
The three core requirements for Medicare eligibility generally center on age (65+ or younger with specific conditions like disability/ESRD/ALS), U.S. citizenship/legal residency (5+ years), and sufficient work history (10 years for premium-free Part A), though some (like ESRD/ALS) bypass age, and individuals must also qualify for Social Security or Railroad Retirement benefits to get premium-free coverage, notes Medicare School.
Falling behind on payments is an easy way to lose Medicare coverage. Everyone on Original Medicare must pay a monthly premium for Part B. If you haven't paid Medicare taxes for 40 quarters or more, you will also pay premiums for Part A. Failure to make your premium payments for a month will result in a second notice.

If you waited 2 full years (24 months) to sign up for Part B and didn't qualify for a Special Enrollment Period, you'll have to pay a 20% late enrollment penalty (10% for each full 12-month period that you could have signed up), plus the standard Part B monthly premium ($202.90 in 2026).

Establish an Irrevocable Trust
Cash, property, and investments can be transferred into an irrevocable trust. By doing so, these assets would be removed from Medicaid's calculation. However, this trust would need to be established at least five years before applying for Medicaid to avoid lookback scrutiny.
