Frequently Asked Health Insurance Questions

At 65, you may be eligible for Medicare. If you’ve already started receiving Social Security benefits, you’ve been automatically enrolled and should receive your Medicare card. If you haven’t started receiving Social Security, you should enroll three months before your 65th birthday. If you miss this window, you could be charged with late enrollment penalties.

Medicare is split into four parts:

  • Part A: This is hospital insurance. It covers hospital or nursing facility care, surgery, hospice and home health care. This coverage is free if you’ve paid into Social Security for at least 10 years.
  • Part B: Part B covers medical services including doctors’ care, outpatient care, labs, tests, medical equipment and some preventive care. You must pay a premium for this coverage.
  • Part C: This allows private companies, like CHRISTUS Health Plan, to provide Medicare Advantage plans, which you can choose instead of original Medicare. These plans cover the same things as original Medicare Parts A and B, but they might have different restrictions and added benefits like dental or vision care. Usually they include drug coverage as well, so all coverage is under one provider. These plans require a monthly premium in addition to your Part B premium.
  • Part D: Part D is prescription drug coverage provided through private companies. You can choose to get a Part D plan that works with Medicare Parts A and B, or you can opt for a Part C Medicare Advantage plan, which will often have it included.
