Your Doctors May Be in Different Cities
You might see your regular doctor in Whittier, visit a specialist in a neighboring city, and go to a hospital somewhere else. Before choosing a Medicare Advantage plan, check whether the specific doctors and hospitals you want to use are included.
A hospital's name or an insurance company's name alone is not enough to confirm coverage. The answer depends on your exact plan and the doctor or hospital.
If you want to keep PIH doctors and also look at Original Medicare with a Medicare Supplement, check the doctors first. A Supplement may ask health questions before it will cover you.

What Is a Medical Group, and Why Does It Matter?
Some Medicare Advantage plans organize care through a medical group or doctor network. A medical group is a set of doctors who work together. That group may help arrange specialist visits and decide which hospital you use.
Ask your doctor's office which medical group your doctor belongs to and whether the group works with the exact plan you are considering. If you need a specialist, ask whether you need a referral or approval first.
A doctor who accepts Medicare does not necessarily accept every Medicare Advantage plan. Original Medicare does not use these medical-group lists the same way. A Medicare Advantage PPO may pay part of a visit to a doctor outside the list, but that does not mean every doctor is covered or that the visit will be inexpensive.

Medical groups and doctor networks near Whittier
These are examples of medical groups that serve parts of the area. Your doctor may or may not belong to one of them. Call your doctor's office to confirm the medical group and ask which Medicare Advantage plans the doctor accepts. Then confirm the details with the insurance plan.
- PIH Health Physicians. The medical group for PIH Health doctors, heard in Whittier, Downey, and Southeast Los Angeles. An IPA that only borrows the PIH name is a different group.
- AltaMed Medical Group. AltaMed’s medical group, tied to its health centers in East Los Angeles, Southeast Los Angeles, and the San Gabriel Valley.
- AppleCare Medical Group. A medical group heard in Southeast Los Angeles and Long Beach.
Broader medical groups also show up in Whittier: Global Care Medical Group IPA, Angeles-IPA, HealthCare Partners Medical Group (Optum), and Optum Care Network–Los Angeles. A countywide medical group is still not your doctor’s group until the office says so.

With some Medicare Advantage plans, your medical group helps arrange referrals to specialists and hospitals. The process depends on your plan. Ask your doctor's office who handles referrals and whether you need approval before seeing a specialist. Your Medicare plan and your medical group has the longer explanation.
Check the Hospital You Want to Use
Think about where you would want to go for a planned procedure, specialist treatment, or hospital stay. Check that hospital against your plan, along with the doctors who would treat you there.
A hospital may belong to a larger health system, but that does not automatically mean every doctor or location in the system accepts your plan.
These are hospitals people in Whittier use. A name here is not a statement that any plan covers that hospital.

- PIH Downey, Kaiser Downey, and some North Orange County hospitals. Other places residents already go. County lines do not enroll you.
Look Beyond the Monthly Premium
A plan with a low monthly premium may still have costs when you visit a doctor, see a specialist, receive outpatient treatment, or stay in a hospital.
Before enrolling, compare the monthly premium, copayments, deductibles, prescription costs, and the maximum you could pay for covered medical services in a year. A copayment is what you pay at the visit. A deductible is what you pay before the plan starts sharing the cost. Also check whether your regular prescriptions are covered.
The right comparison depends on how you use healthcare—not just on which plan advertises the lowest premium.
Four Questions to Ask Before Changing Plans
Write down the answers and confirm important details with the insurance company. If you want help understanding your options, talk with Alan.
- Does my doctor accept this exact plan at the office I visit?
- Which medical group does my doctor belong to, and will I need referrals?
- Can I use my preferred hospital and specialists?
- What will I pay for my regular visits, prescriptions, and other care?
An example in Whittier
This is an example of what to check. It does not mean any doctor or hospital accepts a particular plan.
You want to keep PIH Health doctors, and you are considering Original Medicare with a Supplement instead of Medicare Advantage. The doctor list and the rules for buying a Supplement are separate questions. Talk with Alan.

Hospitals and health systems are not the same thing
A hospital is a specific facility where you receive care. A health system may operate several hospitals and medical facilities. Check the exact location you want to use because coverage at one location does not automatically mean coverage at every location in the system.
