CalPERS Health Benefits in Retirement: The 120-Day Rule Explained

The Rule That Can Cost You Health Coverage for Life

For a CalPERS retiree health plan, you must retire within 120 days of separation, receive a monthly retirement allowance, be eligible for health enrollment on your separation date, and retire from an employer or bargaining unit that contracts for CalPERS health benefits. If more than 120 days pass between separation and retirement, you are not eligible for CalPERS health benefits into retirement. Miss the window, and you may need to buy health insurance on the open market for the rest of your pre-Medicare life.

This 120-day separation rule is the single most consequential deadline in the CalPERS retirement process, and it catches people who assume they can take a few months off between their last day of work and their retirement date.

How the 120-Day Rule Works

Your separation date is the anchor; CalPERS uses your last day on payroll with a CalPERS-covered employer. Your retirement effective date must fall within 120 calendar days of that date. Not 120 business days — calendar days.

Here is a concrete example. Your last day on payroll is March 1. Your retirement date must be no later than June 29 (120 calendar days later). If you set your retirement date to July 1 — just two days past the window — you have permanently forfeited your retiree health benefits.

Confirm the date interval with your employer and CalPERS before filing.

PEMHCA Vesting: What Your Employer Actually Pays

Even if you meet the 120-day rule, the amount your employer contributes toward your retiree health premiums depends on your vesting schedule.

For state employees, the vesting formula depends on your hire date and bargaining unit. State workers hired before January 1, 1985, are fully vested and receive 100% of the maximum state contribution when they retire with at least 10 years of service credit. Those hired from January 1, 1985, through December 31, 2016, generally receive 50% at 10 years, increasing 5% per additional year to 100% at 20 years. Later hires may have extended schedules requiring 15 to 25 years for full vesting, depending on bargaining unit and employee class.

For local government and school employees, vesting schedules vary by employer contract. Some contracting agencies provide 100% from day one. Others use graduated schedules similar to the state formula. A few contract for only the statutory PEMHCA minimum employer contribution, which covers a fraction of the premium.

Check your vesting status with your employer's HR or benefits office. They can tell you exactly what percentage you have earned and what the employer will contribute toward your health plan premium in retirement.

Coordinating Health Coverage With Your Retirement Date

If you are enrolled in a CalPERS health plan and retire within 30 days of separation, coverage generally continues into retirement without a break. If the dates are 31 to 120 days apart, coverage does not automatically continue; contact CalPERS within 60 days of your retirement date to request enrollment or use a future Open Enrollment. Confirm your active coverage end date and retiree coverage effective date with HR and CalPERS, and arrange COBRA or other interim coverage if necessary.

Medicare Coordination at Age 65

If you or a covered dependent is 65 or older, retired, and eligible for premium-free Medicare Part A, CalPERS generally requires enrollment in both Parts A and B to continue CalPERS health coverage through a CalPERS Medicare health plan. If you or your spouse is still working and you have active employer group coverage, you may be able to defer Part B; submit CalPERS's required certification to avoid a coverage cancellation. If you do not enroll when first eligible and do not qualify to defer, a Part B late-enrollment penalty may apply.

When you are nearing 65, contact the Social Security Administration to confirm your enrollment period. If you are deferring Part B because of active employer coverage, ask SSA about the Special Enrollment Period when that coverage ends.

What to Verify Before Filing

Before you submit your retirement application, confirm three things with your employer's HR department:

1. Your exact last day on payroll — not your last day physically at work, but the last day you are carried on payroll and employer contributions are made.
2. Your PEMHCA vesting percentage and the dollar amount the employer will contribute.
3. Whether your employer's health coverage extends through the end of the month of separation or terminates on your last day.

These three facts determine whether you maintain health coverage, what it costs you, and whether you need a COBRA bridge.
