New Mexico retiree health care is administered by the New Mexico Retiree Health Care Authority (NMRHCA), which offers subsidized group medical and prescription coverage to people who retired from a participating public employer. To qualify, you generally need at least five years of contributions from you and your employer, plus a pension from a recognized retirement system. What you actually pay each month depends on your years of service, when you became eligible for the program, whether you are in an enhanced retirement plan, and whether you have reached Medicare age.
Who Qualifies
Coverage is available to retirees whose participating public employer contributed to the NMRHCA fund on their behalf for at least five years.1New Mexico Retiree Health Care Authority. About Us Participating employers include state agencies, counties, municipalities, school districts, and other public entities that have opted into the program. You also need to be drawing a pension from a recognized retirement system such as the Public Employees Retirement Association (PERA) or the Educational Retirement Board (ERB).2Justia. New Mexico Statutes Section 10-7C-2 – Purpose of Act
Spouses, domestic partners, and dependents can be covered under your plan. If a retiree dies, a surviving spouse or dependent who receives a survivor’s pension can enroll separately, but only if they act within 31 calendar days of the change in status.3Cornell Law Institute. New Mexico Admin Code 2.81.6.8
How the Subsidy Is Calculated
NMRHCA does not pay a flat dollar amount toward your premium. It sets a subsidy level for each plan, then pays a percentage of that subsidy based on your years of credited service. Even at 100% of the subsidy, you still pay something, because the subsidy rarely equals the full premium.
Two schedules apply, depending on when you became eligible and whether you retired under an enhanced PERA plan (police officers, firefighters, and corrections officers).4New Mexico State Records Center and Archives. NMAC 2.81.11 – NMRHCA Contribution of a Percentage of a Subsidy
Schedule A: Enhanced Plans, or Eligibility Before July 31, 2021
If you are in an enhanced PERA retirement plan, or you became eligible for NMRHCA on or after July 1, 2001, but before July 31, 2021, you hit the full subsidy at 20 years of service. The scale climbs 6.25 percentage points per year:
- 5 years: 6.25% of the subsidy
- 10 years: 37.50%
- 15 years: 68.75%
- 20 years: 100%
Each additional year matters. Someone with 12 years gets 50%; someone with 8 years gets 25%.4New Mexico State Records Center and Archives. NMAC 2.81.11 – NMRHCA Contribution of a Percentage of a Subsidy
Schedule B: Non-Enhanced Plans, Eligibility On or After January 1, 2021
If you are not in an enhanced plan and became eligible on or after January 1, 2021, you need 25 years to reach the full subsidy:
- 5 years: 4.76% of the subsidy
- 10 years: 28.57%
- 15 years: 52.38%
- 20 years: 76.19%
- 25 years: 100%
The practical gap is real. Under Schedule A, 15 years of service gets you nearly 69% of the subsidy. Under Schedule B, the same 15 years gets just over 52%.4New Mexico State Records Center and Archives. NMAC 2.81.11 – NMRHCA Contribution of a Percentage of a Subsidy
2026 Plans and What You Will Pay
NMRHCA contracts with Blue Cross Blue Shield of New Mexico, Presbyterian Health Plan, Humana, and UnitedHealthcare. The options split by Medicare status.5New Mexico Retiree Health Care Authority. 2026 Summary of Benefits Packet
If you are not yet Medicare-eligible, you choose between a Premier PPO with broader networks and higher premiums, and a Value HMO with narrower networks and lower premiums. Both are offered through BCBS and Presbyterian.
If you are Medicare-eligible, the menu is wider: a BCBS Medicare Supplement PPO, BCBS Medicare Advantage HMO and PPO plans, a Humana Medicare Advantage PPO, a UnitedHealthcare Medicare Advantage PPO, and a Presbyterian Medicare Advantage HMO. The Medicare Advantage options are group plans negotiated by NMRHCA and often carry richer benefits than individual Medicare Advantage plans sold on the open market. Prescription drug coverage is included in both the pre-Medicare and Medicare plans.
For 2026, retirees receiving the full subsidy pay these monthly rates for retiree-only coverage:6New Mexico Retiree Health Care Authority. 2026 Summary of Benefits
- Premier PPO (pre-Medicare): $352.81
- Value HMO (pre-Medicare): $275.60
- BCBS Medicare Supplement: $245.61
Those are floor rates. Fewer years of service, adding a spouse, or adding dependents all raise the bill. And if your eligibility date is July 31, 2021, or later and you retire before age 55, the pre-Medicare Premier PPO climbs to $980.04 per month, with the Value HMO at $765.55.6New Mexico Retiree Health Care Authority. 2026 Summary of Benefits Retiring before 55 is where the math gets uncomfortable.
How NMRHCA Works With Medicare
Once you turn 65 or otherwise become Medicare-eligible, NMRHCA expects you to enroll in Medicare Parts A and B. Your NMRHCA coverage then moves into a supplemental role, filling gaps that Medicare leaves open, including copays, certain deductibles, and services Medicare does not cover. The 2026 lineup includes both Medicare Supplement and Medicare Advantage options.7New Mexico Retiree Health Care Authority. 2026 Medicare Summary of Benefits Packet
IRMAA Surcharges
If your modified adjusted gross income from two years earlier exceeds certain thresholds, Medicare adds an Income-Related Monthly Adjustment Amount (IRMAA) on top of the standard Part B premium. For 2026, the standard Part B premium is $202.90. Surcharges begin when individual income exceeds $109,000 (or $218,000 for joint filers) and can push the total Part B premium as high as $689.90 per month for individuals earning $500,000 or more.8Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles
IRMAA catches retirees who take a large lump-sum retirement account distribution or sell property in a single year, spiking income above a threshold. Because the lookback is two years, spreading withdrawals across multiple years can sometimes keep you in a lower bracket. NMRHCA does not reimburse IRMAA. That cost is yours.
HSA Contributions End at Medicare Enrollment
If you have been contributing to a Health Savings Account under a high-deductible plan, that eligibility ends the month your Medicare coverage begins. You can still spend existing HSA funds on qualified medical expenses, but no new contributions are allowed. Medicare enrollment can be retroactive by up to six months, which can create excess-contribution problems if you time it poorly.
How to Enroll and When to Make Changes
At retirement, you enroll by requesting a general enrollment packet from NMRHCA or downloading it from the website. The packet lists the required documentation. You return the forms and supporting documents by mail or in person at the NMRHCA office in Albuquerque.9New Mexico Retiree Health Care Authority. Frequently Asked Questions
After that, plan changes happen during Open Enrollment, held in October and November before odd-numbered years. Coverage cycles run two years, so if you miss the window, you typically wait until the next odd-year cycle. Open Enrollment in fall 2026 sets your coverage for the cycle beginning January 2027.9New Mexico Retiree Health Care Authority. Frequently Asked Questions Qualifying life events, such as a spouse gaining or losing other coverage, may allow a mid-cycle change, but you must act within 31 days of the event.3Cornell Law Institute.

If NMRHCA makes a decision you believe wrongly affects your eligibility or benefits, the Retiree Health Care Act provides avenues to challenge it.10Justia. New Mexico Statutes Chapter 10, Article 7C – Retiree Health Care Contribution rates, subsidy structures, and plan designs have shifted repeatedly over the program’s history, and further adjustments are likely, so it is worth checking NMRHCA’s published updates each year before your renewal cycle.
