Medicare with other coverage: Medi-Cal, VA, and TRICARE

Medicare often sits next to another program. Medi-Cal, VA, and TRICARE each coordinate differently. This page is a map to the longer explainers — not a payment decision and not a determination that you qualify.

They are not interchangeable

Medicare is federal health insurance, mainly for people 65 or older and certain people with disabilities. Other programs may pay with it, after it, or instead of it for some services. Guessing from a friend’s story is how people skip Part B or drop coverage they still need.

Medi-Cal (California’s Medicaid)

Medi-Cal is based mainly on income, resources, and California rules. Some people have Medicare and Medi-Cal together (often called dual eligible). That can mean help with Medicare costs, and in some ZIP codes Dual Special Needs Plans. Having Medicare does not automatically mean you have Medi-Cal.

VA

Medicare generally does not pay for care at a VA facility. VA coverage does not replace Part B for civilian doctors and hospitals. Many veterans keep both. Skipping Part B because you use the VA can mean a late-enrollment penalty if you later need a community doctor.

TRICARE

TRICARE for Life generally requires Medicare Part A and Part B. Medicare pays first on covered services; TRICARE pays second. Do not drop Part B to save the premium without asking TRICARE. Active-duty TRICARE can work differently.

Read the details that match you

Use the Medi-Cal article if costs or dual eligibility are the question. Use the VA / TRICARE / FEHB article if military, veteran, or federal employee coverage is in the mix. Print the matching worksheet. Confirm with the official program — this website cannot say who pays first on a claim.

Common questions

Can I use one article for all three?
This overview is the map. Medi-Cal and VA/TRICARE follow different rules. Open the article that matches the coverage you actually have.
Does this say I qualify for Medi-Cal or Extra Help?
No. Eligibility is official — California Medi-Cal programs and Social Security. Screeners on this site are sketches only.

Screener

Medi-Cal screener (65+ / disabled)

California 2026 Aged & Disabled FPL sketch for people with Medicare. Not a determination — apply through the county.

This sketch is for Californians who are 65 or older, or who meet Social Security’s disability rules — the usual path for people who already have Medicare. It is not MAGI Medi-Cal for adults under 65. The county decides. This website cannot say that you qualify.

  • Aged & Disabled FPL (no share of cost): 138% FPL — $1,836.00 / $2,490.00 a month (April 2026 DHCS chart)
  • Resource limit: $130,000.00 individual / $195,000.00 couple (reinstated January 1, 2026)
  • Over the A&D FPL income limit, Medi-Cal with a share of cost may still be possible. This tool does not calculate a share-of-cost dollar amount.

Enter income and resources to see which 2026 path this sketch is closest to. Leave a field blank to treat it as $0.

How to apply. Use BenefitsCal or your county social services office. Read DHCS Medi-Cal. In Los Angeles County, call Aging & Disabilities at 800-510-2020 or California HICAP at 1-800-434-0222 (TTY 711). For Part B premium help only, use the Medicare Savings Programs screener.

Worksheet

VA, TRICARE, or FEHB — who pays first?

A checklist, not a payment decision. Medicare, VA, TRICARE for Life, and FEHB stack differently.

Who pays first depends on the program and whether you are still working. This is a checklist — not a payment decision.
