Medicare is a government health insurance program that helps older adults (usually 65 years or older), people with certain disabilities, and those with specific health conditions get affordable healthcare services.

Here's what Medicare covers:

• Part A: Hospital care, nursing facility care, home healthcare, and hospice care.

• Part B: Doctor visits, outpatient services, and medical supplies.

• Part C (Medicare Advantage): Offered by private insurance companies, it combines Part A and Part B coverage into one plan and may include Prescription Drug.

• Part D: Prescription drugs to reduce medication costs.

Medicare doesn't cover everything, so there might be some expenses you have to pay yourself. Some people get additional insurance called Medigap plans to help with these costs.

To join Medicare, you need to meet certain requirements and enroll during specific times. It's important to understand these enrollment periods to avoid penalties and make sure you have healthcare coverage when you need it.
