Medicare Services

What a licensed Medicare agent does for you

Zulema Zamudio Medicare Insurance Agency is an independent, licensed agency on Third Avenue in downtown Chula Vista. Since 2008 we have helped Medicare beneficiaries across San Diego County enrol on time, compare their options honestly, and keep the doctors they already trust. You are never charged for our help — independent agents are compensated by the insurance carriers, not by the people they serve.

Our services

Medicare enrollment help

Turning 65, leaving an employer plan, or already on Medicare and unhappy with your coverage. We explain Parts A, B, C and D in plain language, check your doctors and prescriptions against each plan before you commit, complete the paperwork with you, and review your plan every fall so a quiet benefit change does not cost you in January.

Medi-Cal and Medicaid help

In California, Medicaid is called Medi-Cal, and for many Medicare beneficiaries it pays the Part B premium and the cost sharing Medicare leaves behind. We screen you for Medi-Cal, the Medicare Savings Programs and Extra Help in one sitting, complete the application in English or Spanish, and make sure the annual renewal does not slip past you.

Retirement and Medicare planning

Retirement changes your health coverage before it changes anything else. We map out when to file for Part A, Part B and drug coverage based on your actual retirement date, check whether your employer’s drug coverage is creditable, coordinate a spouse who is not yet 65, and prepare an IRMAA appeal when a life-changing event has reduced your income.

The carriers we work with

We are independent, so we are not tied to one insurer. We represent UnitedHealthcare, Aetna, Blue Shield of California, SCAN Health Plan, Health Net, Brand New Day and Alignment Health. See the full list on our carriers page.

Who we help

  • People turning 65 who have never dealt with Medicare before
  • People working past 65 who need to know when to take Part B
  • People already on a plan whose doctor left the network, or whose drug costs jumped
  • Dual eligibles — people on both Medicare and Medi-Cal
  • People who received a late enrollment penalty notice and want to contest it
  • Families helping a parent who would rather have this explained in Spanish
