What is specific to Calabasas
Doctors sit on both sides of the Los Angeles–Ventura line, and hillside housing is expensive. A Medigap policy is not a provider network. Confirm each doctor’s county and plan, not the drive time.

Hospitals and health systems
A hospital is one building. A health system is the name that runs more than one. The system pin sits on one of those buildings.

Extra help with Original Medicare
Some people with Original Medicare can get extra help lining up their care. This is not a Medicare Advantage network. A pin does not mean your doctor is in it.
Medicare ACCESS
ACCESS started July 5, 2026. Approved groups can help with some long-term health problems, often from home. If you have a Medicare Advantage plan, you cannot use ACCESS. Medicare named these California groups and did not give a street address:
- Aledade Care Solutions of California P.C.
- Cadence Health CA P.C.
- Headspace Medical Group CA P.A.
- Pair Team Medical Group of CA P.C.

LEAD
LEAD is a newer program for groups of doctors who coordinate care for people with Original Medicare. A practice period runs from September 15 through December 31, 2026. The program starts January 1, 2027. On September 21, 2026, Medicare listed 79 groups getting ready. That is not the full 2027 list, and it does not give Los Angeles street addresses.
- CHS LEAD ACO CA, LLCMedicare named this group on September 21, 2026. It did not publish a Los Angeles office.
- United Physicians Association, Inc.Medicare named this group on that list. Its office is in Garden Grove, which is not in Los Angeles County.

Where to ask
These offices explain Medicare. They do not enroll you in a plan.
Four-part verification
Check these four before you compare extra benefits. Ask the office, then confirm the same names on Medicare. gov and with the plan.
- The individual physician, not only the practice name.
- The medical group or IPA that doctor uses for that plan. An IPA is a physician organization that, on many HMO plans, lines up doctors and handles referrals.
- The hospital you want, and whether a referral is required to use it.
- The plan’s contract number, not only the insurance company name. A network is the list of doctors and hospitals that plan pays.
A Calabasas Medicare example
A resident has physicians on both sides of the LA–Ventura line and travels often. Verify service area, exact providers, and routine out-of-area care. Talk with Alan.
Why work with a Medicare agent who understands Calabasas?
Alan starts with the doctors and hospitals you already use in Calabasas, then explains how Original Medicare and Medicare Advantage treat them differently. You decide what happens next.
County edge, two service areas
An LA County plan may not treat a Ventura County doctor as in-network. Original Medicare plus a Supplement generally follows doctors who accept Medicare, which is a different structure. See [Original Medicare or Medicare Advantage? ](/medicare-guide/advantage-vs-supplement).

Questions we hear in Calabasas
Choose a question. The answer stays until you press Back or Next.
Can an LA County Medicare Advantage plan cover Ventura County doctors for a Calabasas resident?
Only if those doctors participate in the exact plan. The county line is not the contract.
What changed when West Hills Hospital became UCLA West Valley?
The campus is part of UCLA Health. System affiliation still does not prove every physician or every plan participates. Confirm the named doctor and the exact plan.
How does Medicare work during travel from Calabasas?
Emergencies have protections. Routine visits may not. Map the months you are away. See the travel article.
Is Medigap subject to hospital networks the way Advantage is?
Medigap works with Original Medicare. It does not use Advantage-style HMO networks. Doctors must still accept Medicare. Confirm acceptance.
