OTRS doesn't decide; your plan does
The Teachers' Retirement System of Oklahoma (OTRS) pays your retirement benefit and, if you qualify, a monthly health insurance supplement toward your premium. It doesn't run a health plan. Retired educators who keep state coverage are in HealthChoice and the other options from the Employees Group Insurance Division (EGID), now part of the Oklahoma Health Care Authority. Once you're on Medicare, EGID's rules decide whether you need Part B:
| Plan through EGID | Part A | Part B |
|---|---|---|
| HealthChoice Medicare supplement (High or Low Option) | Required | Not required, but the plan pays as if you have it |
| Medicare Advantage Prescription Drug (MAPD) plans | Required | Required, and you keep paying the Part B premium |
Without Part B, HealthChoice estimates what Medicare would have paid and pays only its secondary share. You pay the rest, which for most outpatient care is the bigger part of the bill. See do I need Part B with the HealthChoice Medicare supplement.
Why waiting can cost you
Medicare says retiree coverage isn't coverage from current employment, so it doesn't give you a Special Enrollment Period for Part B. If you skip Part B when you first qualify, you may have to wait for the General Enrollment Period (January 1 to March 31) and pay 10% more for each full 12 months you went without it, for as long as you have Part B. In 2026 the standard Part B premium is $202.90 a month; 2027 amounts aren't published yet.
Steps for retired educators
- Sign up for Medicare. If you don't already get Social Security, apply for Part A and Part B with Social Security about three months before you turn 65.
- Watch for EGID's packet. EGID mails Medicare plan information and applications about two months before your 65th birthday. Return your application before your birth month.
- Keep the OTRS supplement. OTRS pays it only while you stay in your employer's coverage. EGID's guide says that if you drop your EGID health plan, you can't regain it later and you lose your retirement system's premium contribution.
- Keep paying both premiums. Part B goes to Medicare. In the state plan, OTRS deducts the rest of your plan premium, after its supplement, from your monthly benefit.

Frequently asked questions
Does OTRS pay my Medicare Part B premium?
No. The OTRS health insurance supplement goes toward your health plan premium, paid to the Oklahoma Health Care Authority's EGID or to your school district's plan. Your Part B premium is separate and is usually taken from your Social Security benefit.
What if my school district has its own retiree plan?
Ask the district or its plan whether Part B is required. Under 74 O.S. § 1316.3, OTRS can pay its supplement to a participating education employer's plan, but that plan sets its own Medicare rules.
I'm still teaching at 65. Do I need Part B now?
If you have health coverage through your current job, you can usually delay Part B without a penalty and sign up within 8 months after the job or coverage ends. Retiree coverage doesn't count as current employment.
