NYSTRS Retirement and Medicare: Part B Reimbursement and Coverage Coordination

Once you turn 65 as a NYSTRS retiree, Medicare enters the picture — and the interaction between Medicare, your district retiree health plan, and your pension creates confusion that catches people off guard every year.

NYSTRS Does Not Provide Health Insurance

This is the essential starting point: NYSTRS administers your pension, not your health insurance. Your retiree health coverage is provided by your former school district under the rules of your collective bargaining agreement and local district policies.

NYSTRS acts solely as a withholding agent. If your district health plan deducts premiums from your pension, NYSTRS processes that deduction. But NYSTRS has no role in determining your coverage, your premium, or your eligibility.

Medicare Part B Enrollment at 65

When you turn 65, you become eligible for Medicare. Most NYSTRS retirees need to enroll in Medicare Part B (medical insurance) during their Initial Enrollment Period — the seven-month window centered on the month they turn 65.

Do not assume retiree health coverage gives you a Special Enrollment Period based on current employment. If you or your spouse has active employer coverage, different rules may apply; confirm your enrollment period and any late-enrollment penalty with Social Security before declining Part B.

If you are still actively employed at 65 (returning to public service under Section 212 or continuing in a non-NYSTRS position), different rules may apply. Check with Medicare directly.

How District Plans Coordinate With Medicare

District requirements vary. Confirm whether your plan requires enrollment in Medicare Parts A and B when you become eligible at age 65 and how it coordinates coverage. If Medicare is primary, the district plan may act as secondary, but the specific coverage depends on your plan.

Some districts participate in the New York State Health Insurance Program (NYSHIP), while others run independent district plans. The coordination rules depend on which plan your district offers:

NYSHIP participants: Ask NYSHIP and your district how your specific Empire Plan or NYSHIP HMO option coordinates with Medicare and what enrollment steps are required.

Independent district plans: Coordination varies by plan. Some mirror NYSHIP's approach. Others require specific enrollment steps or have their own Medicare supplement structure. Contact your district HR for the specific coordination rules.

Medicare Part B Premium Reimbursement

Many New York school districts reimburse retirees for some or all of the Medicare Part B premium. This reimbursement is a district benefit, not a NYSTRS benefit — the terms are set by your CBA and district policy.

The standard Medicare Part B premium changes annually. Check Medicare's current premium schedule for the amount that applies to your year; higher-income retirees may pay more under the Income-Related Monthly Adjustment Amount (IRMAA).

Districts that reimburse typically do one of the following:

• Full reimbursement of the standard Part B premium, paid as a credit against your health insurance premium deduction or as a separate payment
• Partial reimbursement up to a fixed dollar amount set by the CBA
• No reimbursement — you absorb the Part B premium as an additional cost of coverage

Check your CBA for the specific terms. The reimbursement amount often appears as a line item on your monthly pension statement, separate from your health insurance premium deduction.

The Cost Shift at 65

For many NYSTRS retirees, turning 65 changes the math on health coverage. Before 65, the district plan may be primary and you pay the retiree premium share, subject to any separate district health-premium credit. When Medicare becomes primary, you pay the Part B premium plus any district premium that applies.

Whether you pay more or less overall depends on your district's specific premium structure and reimbursement policy. Run the numbers for your situation:

1. Your current retiree health premium (pre-65)
2. The Medicare Part B premium
3. Any Part B reimbursement from your district
4. Your post-65 district premium, if the plan's Medicare coordination changes it

If your district plan requires Part B, opting out may affect your coverage. Confirm the consequences with your district before deciding.

What NYSTRS Retirees Should Do Before 65

Start planning six months before your 65th birthday:

• Confirm your Medicare enrollment timeline with Social Security (online at ssa.gov or by calling your local SSA office)
• Contact your district HR to understand how your retiree health plan coordinates with Medicare and whether Part B reimbursement applies
• Review your pension statement to understand current health premium deductions and how they will change
