Eligibility is simple. If you’re at least 65, you must be:

  • Enrolled in Medicare Parts A and B.
  • A resident of the state where the plan is offered.

If you’re under 65 and disabled, you must be:

  • Getting Social Security Disability Insurance for 24 consecutive months, Or
  • Be diagnosed with ALS (Amyotrophic Lateral Sclerosis), in which case Medicare starts immediately

Enrollment Periods

You can enroll in a Medicare Supplement Insurance Plan during the six-month open enrollment period that starts once you’re 65 and have Medicare Part B. This six-month open enrollment period is the best time to enroll because it’s the only time when enrollment is guaranteed. If you want a Medicare Supplement Insurance Plan after the open enrollment period, you may have to meet certain requirements and could pay more for the plan.

Guaranteed Eligibility

The best time to buy a Medicare Supplement insurance policy is around the time you turn 65. You have guaranteed acceptance during the six-month Open Enrollment Period that begins on the first day of the month in which you turn 65 and are enrolled in Medicare Part B. If you are under 65, have Medicare Part A and are within the six months following your enrollment for Medicare Part B, your acceptance is guaranteed for Plan A. If you are under age 65 and on Medicare, you will also have a six-month Open Enrollment Period when you reach age 65, beginning on the first day of the month in which you turn 65. In any scenarios, you must have Medicare Part B to be eligible for a Medicare Supplement insurance policy.

Reduced Premium Options for Plans With Limited Networks

Some Medicare Supplement Insurance Plans have a money saving option called Medicare Select. With this option, the Medicare Part A deductible is covered for non-emergency care at Medicare Select hospitals. If it’s an emergency, the Part A deductible is covered at any hospital.

Medicare Select is not an HMO. You can choose your own doctors and specialists. To avoid paying the Part A deductible, you must agree to use a Medicare Select hospital for non-emergency care.

You’re eligible if you live within 30 miles of any Medicare Select hospital. Find a list of Medicare Select hospitals.  Plans F, G, K, L and N have Medicare Select options in Illinois.

Only certain hospitals are network providers under this policy. Check with your doctor to find out if he or she has admitting privileges at the network hospital. If he or she does not, you may be required to use another doctor at the time of hospitalization or, if you still use a non-network hospital, you must pay the Part A deductible and any non-covered charges.

  1. ‭Medicare Select Plans require that you use Blue Cross and Blue Shield of Illinois contracting Medicare Select hospitals for ‭non-emergency admissions to receive coverage for the Medicare Part A deductible. In an emergency, the $1,364 deductible is covered at any hospital from which you receive care. Only certain hospitals are network providers under this policy. Check ‭with your physician to determine if he or she has admitting privileges at the network hospital. If he or she does not, you may ‭be required to use another physician at ‬‬‬the time of hospitalization or you will be required to pay for all expenses. If you move out of the service area, there will be a reduction of benefit coverage and you will have the opportunity to purchase any Medicare Supplement policy with comparable or lesser benefits offered by the insurer, or Medicare Supplement/Select plans A, ‭B, C, F, K, or L from any insurer within 63 days of termination.‬‬
  2. You must live within 30 miles of a participating Medicare Select hospital to be eligible.
  3. Not to exceed any charge limitation established by the Medicare program or state law.

This includes the Medicare deductibles for Part A and Part B, but does not include the plan’s separate foreign travel emergency deductible.
