Medicare plans:

  • TRICARE for Life (Medicare supplement)
  • Medicare Medigap/Supplemental Plans (i.e. AARP, TRICARE for Life)
  • Including Blue Shield Supplement Indemnity Plan

Here is a very basic description of the differences between the various Medicare plans offered:

  • HMO. With HMO plans you can only go to doctors, specialists, or hospitals on the plan's list except in an emergency. Your costs may be lower than in the Original Medicare Plan.
  • PPO. PPO plans are a type of Medicare Advantage Plan available in a local or regional area in which you pay less if you use doctors, hospitals, and providers that belong to the network. You can use doctors, hospitals, and providers outside of the network for an additional cost.
  • Medicare Supplement (Medigap) Plans. This is not a Medicare Advantage plan. When you sign up for a Medigap plan, Medicare is the primary payer and the Medigap plan is your secondary insurance. There are 13 standardized plans that are sold by private insurance companies (Blue Shield of California, HealthNet, etc...) labeled A through N. The monthly premium varies between plans and is dependent on the county where you live and your age. To get a list of companies that sell these plans, call HICAP at 1-800-434-0222 and ask for a list of Medigap plans in your county.
  • Medicare Part D-Outpatient Prescription Drug Coverage. This is in addition to your Medicare Part A and Part B. If you sign up for a Medicare Part C plan, that plan may or may not include Part D drug coverage. If it doesn't include it or you have a Medigap plan, you may want to enroll in a Medicare Part D plan to cover your outpatient prescription drugs.

What is HICAP (Health Insurance Counseling and Advocacy Program)?

HICAP, the Health Insurance Counseling and Advocacy Program, was established by the California Department of Aging under 1984 legislation signed by Governor George Deukmejian. The program is designed to provide Medicare beneficiaries and persons 60 years of age and older with assistance in dealing with Medicare, HMOs, long-term care insurance, and other health insurance issues. The North Bay HICAP office assists people living or moving to Lake, Mendocino, Marin, Napa, Solano, and Sonoma Counties.

The success of the HICAP program is achieved through responsible, committed volunteers who want to help others. HICAP's staff and volunteers receive extensive initial training, as well as subsequent training workshops. Once a volunteer counselor has completed the necessary hours to counsel, they are registered with the California Department of Aging. All services are provided free of charge.

HICAP provides two main services - individual counseling and community education presentations:
