Medicare is a government-sponsored health insurance program designed to provide coverage for people who are 65 years of age or older, as well as those with certain disabilities or chronic health conditions. The program is divided into four parts: A, B, C, and D.

Medicare Part A covers hospital stays, skilled nursing care, and some home health services. It is funded by payroll taxes and is generally available to people who have paid into the Social Security system for at least 10 years.

Medicare Part B covers doctor visits, outpatient care, and some preventative services. It is funded by a combination of premiums paid by beneficiaries and general tax revenue.

Medicare Part C, also known as Medicare Advantage, is an alternative to traditional Medicare that allows beneficiaries to receive their Medicare benefits through a private insurance plan. These plans may offer additional benefits such as dental, vision, and hearing coverage.

Medicare Part D covers prescription drugs, and is also funded by a combination of beneficiary premiums and general tax revenue.

Medicare is an important resource for millions of Americans who rely on the program to access critical health care services. While the program has faced challenges in recent years due to rising costs and changing demographics, it remains a vital lifeline for many seniors and people with disabilities.

Medi-Cal is a California state-administered health insurance program that provides coverage for low-income individuals, families, and children, as well as people with disabilities and seniors who meet certain eligibility requirements.

Medi-Cal offers a comprehensive range of medical services, including preventative care, doctor visits, hospitalization, prescription medications, mental health services, and dental and vision care. The program is funded by both federal and state tax dollars, and is available to residents of California regardless of their immigration status.
