What is Medicare?

Medicare is a federal health insurance program designed to cover the basic health care needs of seniors aged 65 and above. The program is divided into 4 parts:

Part A plans cover inpatient hospital stays, skilled nursing facilities and some home care.

Part B plans cover doctors, specialists and other outpatient appointments. Part A and Part B plans are known as Original Medicare.

Part C plans, known as Medicare Advantage plans, refer to all-in-one Medicare coverage from private insurance companies. Part C plans replace Part A and Part B. Medicare Advantage plans often include extras not found in Original Medicare plans, such as wellness incentives and fitness programs. Many Medicare Advantage plans also offer prescription drug coverage, but Original Medicare plans don’t include it.

Part D plans cover prescription drug costs, can be offered as standalone plans or added on to Original Medicare or Medicare Advantage plans.

Medicare supplemental insurance plans or Medigap plans are designed to fill in the gaps not covered by Original Medicare or Medicare Advantage plans. Medigap plans are offered by private insurers.

Legalities of Medicare in California

Your Medicare rights in California are the same as in any other state. Medicare is a national insurance program for individuals and spouses who are 65 and older and who have paid Medicare taxes during their working years. Those enrolled are guaranteed certain rights:

  • Privacy
  • Fair and ethical treatment
  • The health care services you’re entitled to

The Center for Medicare and Medicaid Services (CMS) is the federal agency that administers the Medicare program and works with state governments to ensure Medicare beneficiaries receive the services they’re entitled to and also make sure that Medicare Advantage plans are high-quality, accessible and affordable. Private insurance companies must adhere to CMS standards and guidelines. They can be fined or penalized or their plan can be terminated if they fall short. You can find claims and appeals resources on and if you feel your rights have been violated. 

Types of Medicare Advantage Plans  

There are 2 main types of Medicare Advantage plans: health maintenance organizations (HMOs) and preferred provider organizations (PPOs).

Health Maintenance Organizations (HMOs)

HMOs are Medicare Advantage plans that consist of regional networks of doctors, specialists and hospitals. You choose a primary care doctor within the network and if you need to see a specialist, you must get a referral from your doctor. HMO plans are usually cheaper than PPOs and more restrictive. 

Most HMOs require plan members to stay healthy by keeping their blood pressure down, exercising, eating right and not smoking — and there are programs available to help you get back on track. You can’t switch primary care doctors unless you do so through the plan.

Preferred Provider Organizations (PPOs) 

PPOs are Medicare Advantage plans that feature a large network of doctors, specialists and hospitals that all agree to accept established rates for services and care. PPOs allow members the freedom to see any doctor they’d like to within the network and referrals aren’t needed. You’ll pay a bit more if you see providers outside the network. 

All Medicare Advantage plans are given star ratings from CMS based on annual performance, customer satisfaction, provider choice, accessibility and rates. Star ratings range from 1 (poorest) to 5 (outstanding). New plans won’t usually be assigned a star rating until they’re on the market at least 1 or 2 years. 

How to Sign Up for Medicare Advantage in California

About 6 months before your 65th birthday, you’ll receive a lot of brochures from private insurance companies promoting their Medicare Advantage plans. Most offer free informational seminars you can attend to help you make your decision. 

You can also visit, the official U.S. government site for Medicare information. The site, run by CMS, explains Medicare and your rights, and features resources such as claims and appeals, forms and a plan finder tool that allows you to put your information in so you can compare plans. You can also sign up for a Medicare Advantage plan on the site. 

Another way to sign up is to contact a sales agent from the company of your choice. The sales agent will walk you through the process. You must sign up for Medicare 3 months before you turn 65 or 3 months after — if not, you could pay a stiff penalty. One exception to this rule, known as the Special Enrollment Period, allows you to enroll in a plan if you’ve experienced a life-changing event such as a marriage or move. 

Another exception is if you already have Medicare and want to enroll in a 5-star plan, you can do so even if it’s not during open enrollment. Medicare’s Open Enrollment Period, which runs from October 15 through December 7 each year, is the only time you can switch plans.
