The minimum age for Medicare eligibility is sixty-five.
But, if your spouse has been getting Social Security disability benefits for twenty-four months, they can receive Medicare at any age.
Otherwise, you can purchase coverage from a private insurance company for your spouse until they turn age sixty-five.
Contact your State Health Insurance Assistance Program to discuss your options and go to eHealthInsurance.com to compare private insurance plans.
