Medicare Parts A, B, C, and D: A Simple Guide for Temecula Residents
If you're approaching 65 or helping a loved one navigate Medicare, you've probably heard about Parts A, B, C, and D. It sounds like alphabet soup, doesn't it? Don't worry—I work with Temecula residents every day who feel the same way. Let me break it down in plain English.
What Is Original Medicare?
Before we dive into the parts, let's start with the foundation. Original Medicare is the federal health insurance program that most people become eligible for at age 65. It consists of two parts:
Part A (Hospital Insurance)
Part B (Medical Insurance)
Think of Original Medicare as the base model. It provides solid coverage but has some gaps—which is where Parts C and D come in.
Medicare Part A: Hospital Insurance
What Does Part A Cover?
Medicare Part A covers inpatient hospital care and several other facility-based services:
Inpatient hospital stays - Your room, meals, nursing care, and other hospital services
Skilled nursing facility care - Short-term rehab after a hospital stay (not long-term care)
Hospice care - Comfort care for terminal illnesses
Home health care - Part-time skilled nursing or therapy services at home
Inpatient care in a religious non-medical health care institution
What's the Cost?
Most people don't pay a monthly premium for Part A because they (or their spouse) paid Medicare taxes while working. However, there are other costs:
Hospital deductible: $1,736 per benefit period (2026)
Coinsurance: After 60 days in the hospital, you'll pay daily coinsurance amounts
Skilled nursing coinsurance: $217 per day for days 21-100 (2026)
Important note: Part A has no out-of-pocket maximum, which means costs can add up for extended hospital stays.
Medicare Part B: Medical Insurance
What Does Part B Cover?
Part B covers outpatient medical services and preventive care:
Doctor visits - Primary care, specialists, and outpatient services
Preventive services - Annual wellness visits, screenings, vaccines (often at no cost)
Outpatient surgery - Procedures done in hospitals or surgical centers
Diagnostic tests - X-rays, lab work, CT scans, MRIs
Durable medical equipment - Wheelchairs, walkers, hospital beds
Ambulance services - When medically necessary
Mental health services - Outpatient therapy and counseling
Limited outpatient prescription drugs - Some medications given in a doctor's office
What's the Cost?
Monthly premium: Most people pay $202.90 (2026 standard premium), though higher earners pay more
Annual deductible: $283 (2026)
Coinsurance: 20% of Medicare-approved amounts for most services
Example: If your doctor visit costs $100 (Medicare-approved amount), you'd pay $20 after meeting your deductible.
When Should I Enroll in Part B?
Your Initial Enrollment Period is 7 months: 3 months before your 65th birthday, your birthday month, and 3 months after. If you're still working with employer coverage, you might delay Part B without penalty—but there are rules. Let's discuss your specific situation.
Medicare Part C: Medicare Advantage Plans
Here's where it gets interesting. Part C is different from Parts A and B.
What Is Medicare Advantage?
Medicare Advantage (MA) plans are offered by private insurance companies approved by Medicare. When you enroll in a Part C plan, you're still in Medicare—you just receive your benefits through the private insurer instead of directly from the federal government.
Important: You must have Part A and Part B to enroll in a Medicare Advantage plan.
What Do Medicare Advantage Plans Cover?
Medicare Advantage plans must cover everything Original Medicare covers (Parts A and B), but they often include extras:
✅ Prescription drug coverage (Part D) - Most MA plans include this
✅ Dental coverage - Cleanings, fillings, sometimes dentures
✅ Vision coverage - Exams, glasses, contacts
✅ Hearing aids - Exams and devices
✅ Fitness benefits - Gym memberships, fitness classes
✅ Over-the-counter allowances - $50-150/month for health items
✅ Transportation to appointments
✅ Telehealth services
Types of Medicare Advantage Plans
HMO (Health Maintenance Organization)
Lower costs, smaller networks
Requires referrals to see specialists
Generally no out-of-network coverage except emergencies
Popular in Riverside County
PPO (Preferred Provider Organization)
More flexibility to see any provider
Higher costs but broader network
Can see specialists without referrals
Good for winter visitors (snowbirds)
Special Needs Plans (SNPs)
Designed for specific conditions or circumstances
Example: Dual-eligible (Medicare + Medi-Cal)
The Trade-Off: Network Restrictions
The biggest difference between Original Medicare and Medicare Advantage is network restrictions. With Original Medicare, you can see any doctor that accepts Medicare (most do). With Medicare Advantage, you typically need to stay within the plan's network.
For Temecula residents: Most major local healthcare providers participate in Medicare Advantage networks, but always verify your doctors are included before enrolling.
Medicare Part D: Prescription Drug Coverage
What Is Part D?
Part D is prescription drug coverage. It's offered by private insurance companies approved by Medicare.
Important: If you have Original Medicare (just Parts A and B), you need to enroll in a separate Part D plan. Most Medicare Advantage plans already include drug coverage.
How Does Part D Work?
Part D plans have several cost stages throughout the year:
Deductible phase: You pay full price until you meet the deductible (varies by plan, often $0-$615)
Initial coverage phase: You pay copays or coinsurance (typically $0-$47 per prescription)
Catastrophic Coverage: Once your total out-of-pocket drug costs hit $2,100 (2026 limit); you pay $0 for covered drugs for the rest of the year.
Choosing the Right Part D Plan
The best Part D plan for you depends on:
Your medications - Different plans cover different drugs
Your pharmacy - Preferred vs standard pharmacies affect costs
Mail order options - Can save money on maintenance medications
Pro tip: Plans change every year. Even if you're happy with your current plan, review it annually during the Annual Enrollment Period (October 15 - December 7).
How Do All the Parts Work Together?
Let's look at two common coverage combinations:
Option 1: Original Medicare + Supplement + Part D
Part A + Part B (Original Medicare)
Medicare Supplement Insurance (Medigap) to fill gaps
Part D prescription plan
Best for: People who want complete freedom to see any doctor, travel frequently, or have complex health needs
Option 2: Medicare Advantage (Part C)
Part A + Part B (still enrolled, but benefits through private plan)
Part C Medicare Advantage plan (often includes Part D)
Best for: People who prefer lower monthly costs, want extra benefits like dental/vision, and are comfortable with network restrictions
What's NOT Covered by Original Medicare?
Important gaps to know about:
❌ Routine dental care, cleanings, fillings, dentures
❌ Routine vision exams, eyeglasses, contacts
❌ Hearing aids and exams
❌ Long-term care (nursing homes, assisted living)
❌ Most care outside the United States
❌ Cosmetic surgery
❌ Acupuncture (with some exceptions)
Common Questions I Hear in Temecula
"Do I have to enroll in Medicare at 65?"
Not always. If you're still working and have employer coverage through a company with 20+ employees, you can delay Part B without penalty. We should discuss your specific employment situation.
"Can I switch plans later if I don't like my choice?"
Yes, but timing matters:
Medicare Advantage Annual Enrollment Period: October 15 - December 7
Medicare Advantage Open Enrollment: January 1 - March 31 (can switch to different MA plan or back to Original Medicare)
Part D can be changed: October 15 - December 7
"How do I know which option is best for me?"
Great question! It depends on several factors:
Your current health and medications
Your preferred doctors and hospitals
Your budget for premiums vs out-of-pocket costs
Whether you travel
Your comfort with network restrictions
This is exactly what I help Temecula residents figure out—at no cost to you.
The Bottom Line
Medicare doesn't have to be complicated:
Part A = Hospital Insurance (usually premium-free)
Part B = Medical Insurance (doctor visits, outpatient care)
Part C = Medicare Advantage (alternative way to get A + B benefits, often with extras)
Part D = Prescription Drug Coverage (needed if you have Original Medicare)
