Quick Take
Medicare can help cover hospital care, doctor visits, preventive services, some home health care, and many medically necessary services.
What surprises patients most is what Medicare does not fully cover — especially long-term care, routine dental, hearing aids, and routine vision care.
Medicare Advantage plans may include extra benefits, but they can also have networks, referrals, prior authorizations, and plan-specific rules.
A yearly wellness visit is covered, but it is not the same as a full physical exam.
Fresno seniors should review Medicare coverage before major tests, procedures, hospital discharge, or plan changes.

1) Medicare Basics: The Parts Most Patients Hear About
Medicare can feel confusing because there are different “parts.”
Here is the simple version:
Part A usually helps cover hospital-related care, such as inpatient hospital stays, skilled nursing facility care, hospice care, and some home health care.
Part B usually helps cover doctor visits, outpatient care, medical supplies, and preventive services.
Part D helps cover prescription medications through a drug plan.
Medicare Advantage, also called Part C, is a private plan option that replaces how you receive Part A and Part B benefits and often includes drug coverage.
The details matter because two patients can both “have Medicare” but have very different coverage, costs, networks, and rules.

2) What Original Medicare Usually Covers
Original Medicare may help cover many medically necessary services, including:
Doctor visits
Specialist visits
Lab work
Imaging when medically necessary
Hospital stays
Emergency care
Preventive screenings
Some vaccines
Durable medical equipment when covered
Some home health care
Hospice care
Skilled nursing facility care when requirements are met
Many preventive services may be covered with little or no cost if the provider accepts Medicare assignment, but not every visit or test is automatically free.
For example, a Medicare wellness visit can help review prevention, screenings, medications, health risks, and care planning — but it is not the same thing as a full head-to-toe physical exam.

3) What Medicare Does Not Cover Well
This is where many patients are surprised.
Original Medicare generally does not cover:
Long-term custodial care
Most routine dental care
Dentures
Routine eye exams for glasses
Hearing aids
Routine foot care in many cases
Cosmetic surgery
Most care outside the United States
Private-duty nursing
Many non-medical home care needs
This matters because many seniors assume Medicare will cover help with bathing, dressing, cooking, cleaning, transportation, or long-term supervision at home.
In many cases, those needs fall under caregiving, long-term care, Medi-Cal, IHSS, private pay, or other support programs — not standard Medicare medical coverage.

4) What patients often misunderstand
1) “Medicare covers everything once I turn 65”
Not exactly.
Medicare covers many important medical services, but it does not cover everything. Patients still need to understand premiums, deductibles, copays, coinsurance, drug coverage, and plan rules.
2) “A wellness visit is a full physical”
A Medicare wellness visit is focused on prevention and care planning. If extra problems are addressed or additional testing is done, there may be separate costs depending on the service and plan.
3) “Medicare Advantage and Original Medicare work the same way”
They are not the same.
Medicare Advantage plans must cover medically necessary services that Original Medicare covers, but they may use provider networks, referral rules, prior authorization, and plan-specific costs.
4) “If my doctor orders it, Medicare automatically pays”
Not always.
Coverage may depend on medical necessity, diagnosis, plan rules, prior authorization, network status, and whether the service meets Medicare requirements.
5) “My drug plan covers every medication”
Drug plans have formularies, tiers, preferred pharmacies, prior authorizations, and possible medication changes each year. Patients should review medications during open enrollment and after major health changes.

5) Fresno Checklist Before Appointments or Plan Changes
Before a major appointment, test, procedure, or plan change, Fresno seniors should check:
What Medicare plan do I have?
Are my doctors in network?
Are my medications covered?
Do I need a referral or prior authorization?
What will my copay or coinsurance be?
Is this a preventive visit or a problem-based visit?
Did anything change after a hospital discharge?
Do I need help with home care, transportation, meals, or caregiving?
Bring these items to your appointment:
Medicare card and plan card
Medication list
Pharmacy list
Specialist names
Hospital discharge paperwork if recent
Questions about coverage or next steps
The goal is to avoid surprises before they become stressful or expensive.
