Local Medicare Resources

Residents of California that qualify or are enrolled in Medicare can receive free personalized and unbiased Medicare counseling and education from the California Health Insurance Counseling and Advocacy Program (HICAP), a part of a national network of State Health Insurance and Assistance Programs (SHIP). Additionally California's Senior Medicare Patrol (SMP) helps Medicare beneficiaries detect, avoid, and report healthcare fraud and abuse.

Types of Medicare Coverage

When you are eligible for Medicare you may sign up for Original Medicare (Part A & Part B), which cover hospital services and medical services, respectively, or you may enroll in a Medicare Advantage Plan (Medicare Part C). Keep in mind that you must be eligible for Original Medicare in order to enroll in a Medicare Advantage plan. If you sign up for Original Medicare you also have the option to purchase a separate or stand alone prescription drug plan (Part D). Original Medicare offers its beneficiaries flexibility in choosing their providers and you are not limited to a network. However, there is no limit on out-of-pocket medical expenses and you must always pay 20% coinsurance for medical service costs. For most Medicare beneficiaries, Part A is already paid through paycheck deductions during their working years (or their spouse's) but most Medicare beneficiaries pay premiums for Part B unless they qualify for financial assistance. Medicare Advantage plans require you to stay in network but some plans will also cover out-of-network care at a higher cost. Many Medicare Advantage plans also include additional health benefits such as vision, dental, or hearing coverage and you have the option to purchase a Medicare Advantage plan with prescription drug coverage (MAPD) in almost all states.
