CalPERS How Much Do I Pay for Medicare Explained
Understanding Your Medicare Part B Premium for 2025
Every CalPERS retiree enrolling in a Medicare plan needs to consider the cost of Medicare Part B coverage. For 2025, the standard Medicare Part B premium is set at $185 per month. However, this standard rate doesn’t apply to everyone—higher-income retirees may pay more due to the Income-Related Monthly Adjustment Amount, or IRMAA.
IRMAA is an additional fee that applies to people whose income exceeds set thresholds, as determined by the IRS and Social Security. If you are subject to IRMAA, you’ll see higher monthly Part B costs, which could affect your overall health care budget.
Updates for 2025 confirm both a moderate increase in the base Part B premium and revised IRMAA brackets. These changes ensure that higher earners help offset Medicare’s rising costs—a topic explored more in our Medicare yearly budget breakdown. It’s important for retirees to check their latest Social Security income notice or the official Medicare website to see whether IRMAA will apply to them in the coming year.
Breaking Down CalPERS Medicare Plan Premiums and the 22.25% Increase
CalPERS offers a variety of Medicare health plans, each with its own monthly premium. For 2025, the average CalPERS Medicare health plan premium is rising by 22.25%. This means, for instance, if your plan’s premium was $400/month in 2024, it could increase to roughly $489/month in 2025.
This jump is much larger than typical annual increases seen in prior years, making it essential to revisit your health plan options and understand what’s driving these costs. The sharp 22.25% increase is attributed to multiple factors:
- General health care price inflation and higher medical utilization by retirees
- Increased cost of prescription drugs and medical technology
- Contract renegotiations and actuarial adjustments to keep plans solvent
- Rising federal requirements for minimum Medicare coverage standards
This year’s increase is among the largest on record. In previous years, CalPERS Medicare plans saw more modest single-digit increases, so the 2025 jump is a significant trend reversal retirees should prepare for.
Role of Employer Contributions in CalPERS Medicare Premiums
Your CalPERS employer contribution can substantially offset your premium costs. Here’s how it typically works—
- State and CSU retirees receive a percentage of the state’s standard contribution, based on years of service (“vesting”).
- Public agency and school retirees have their contributions set by contract; these can vary widely.
Vesting requirements determine whether you qualify for the full employer contribution or a partial amount. For example, you may need 20 years of service to receive 100% of the state rate, with lower percentages for shorter careers.
Let’s illustrate the impact:
- Plan premium: $500/month
- Full employer contribution: $500/month (your net cost: $0 for that plan)
- Partial employer contribution: $350/month (you pay $150/month difference)
This employer offset can make a major difference in your out-of-pocket cost structure and should be factored in when comparing plans or estimating your annual healthcare expenses.

Medicare Part B Premium Reimbursement Through CalPERS
As a CalPERS retiree, you may qualify for reimbursement of your Medicare Part B premium. For 2025, this automatic reimbursement equals up to $185 per month—the standard Part B premium.
Here’s how it works:
- Eligible state and CSU retirees: CalPERS automatically reimburses the standard monthly Part B amount as part of your pension check.
- If you pay more because of IRMAA: You can request additional reimbursement for the IRMAA surcharge, but you must submit proof (like your SSA-1099 or Social Security letter) within CalPERS’s timelines to claim this benefit.
Reimbursement reduces your net Medicare costs, but it’s essential to maintain good records and respond promptly to any CalPERS information requests to avoid delays or denial of funds.

How CalPERS Determines Premium Increases Across Different Medicare Health Plans
CalPERS collaborates with plan providers and actuaries to set premiums annually. Adjustments are based on projected costs, healthcare utilization, and federal coverage mandates for Medicare Advantage and Supplement plans. HMO and PPO plans are evaluated separately to reflect their different risk pools and utilization trends.
These factors all play a role:
- Contract rates renegotiated annually with health plans
- Analysis of prior year’s claims and utilization statistics
- Forecasted healthcare inflation for the upcoming year
- Changes in federal Medicare rules or payment benchmarks
For example, prescription drug price inflation has been a major driver of increased plan costs, as has increased use of high-cost services by retirees. The result: higher monthly premiums for most plans in 2025 compared to the more moderate upticks of previous years.

Comparing HMO and PPO Plans: Impact on Premiums and Out-of-Pocket Costs
The two main categories of CalPERS Medicare plans—HMO and PPO—vary in premiums and flexibility:
- HMO plans typically have lower premiums and more restrictions (must use in-network providers, need referrals for specialists).
- PPO plans have higher premiums but greater flexibility (see any provider, no referral needed).
For 2025, most CalPERS HMO plans saw smaller premium increases than PPO plans, but the gap between HMO and PPO pricing has widened. PPOs are optimal for retirees wanting flexibility and nationwide access, while HMOs best serve those focusing on lower monthly costs and who are comfortable staying within a network.
