Counting the city, not the ZIP code
Because most of the land in 91361 and 91362 lies in Ventura County, the figures below cover the City of Westlake Village alone, not its ZIP codes. More than one person in four in the city is 65 or older: 2,157 of 7,743 people, or 27.9 percent, next to 15.2 percent for the county. The city's median age, 49.0, sits more than ten years above the county's 38.2. Four in five occupied homes in the city are owned by the household living there (2,390 of 2,967, or 80.6 percent). The county rate is 45.9 percent. Half of the city's households take in more than $179,954 a year. Every number here is from the Census Bureau's American Community Survey for 2020 to 2024. We totaled the survey's age brackets to get the number of people 65 and older.
The closest hospital is in Thousand Oaks
Westlake Village has no hospital of its own. Measured from the center of the city, the closest is Los Robles Hospital and Medical Center at 215 W Janss Rd in Thousand Oaks, across the line in Ventura County. It has an emergency department. To the east, in the west Valley, UCLA West Valley Medical Center at 7300 Medical Center Dr in West Hills is licensed for 249 beds. Providence Cedars-Sinai Tarzana Medical Center, at 18321 Clark Street, is licensed for 204. Kaiser Foundation Hospital Woodland Hills, at 5601 De Soto Ave, is licensed for 274, and apart from emergencies it serves only Kaiser plan members. The bed counts come from the state licensing records we pulled for Los Angeles County in September 2026, which is why Los Robles, in Ventura County, has none listed. For a Westlake Village household, the question to ask of any Medicare Advantage plan is whether its medical group admits patients at Los Robles or only in the Valley. The answer is in the plan's provider directory, not its name. Medical groups' contracts come up for renewal, so a plan that includes Los Robles one year can drop it the next. Before you sign anything, Lara searches each plan's current directory for Los Robles, your doctors and your pharmacy. She repeats the search every fall, once plans have posted what is changing.
Your neighbor in Thousand Oaks has a different plan list
Inside the Westlake Village city limits, you choose from the Los Angeles County list of Medicare Advantage plans. A neighbor a few streets west, in Thousand Oaks, chooses from Ventura County's list, even with the same ZIP code. If you move across that line for good, you get a Special Enrollment Period to change plans. Original Medicare with a Medicare Supplement works at any doctor's office or hospital in the country that takes Medicare, Los Robles included. Since Los Robles is in some plans' networks and not others, that pairing deserves a real comparison with Medicare Advantage. Our Ventura County Medicare Supplement table puts 91361 and 91362 in the group of ZIP codes we call rate area B and shows what each insurer charges there for Plan G at 65, from the California Department of Insurance's Ventura County search.
Medicare Advantage across Los Angeles County in 2027
About 57 percent of Los Angeles County's 1.7 million Medicare beneficiaries are enrolled in Medicare Advantage or another Medicare health plan (CMS, May 2026). The county has 70 Medicare Advantage plans open to general enrollment in 2027, plus 54 Special Needs Plans, and 60 of the 70 charge a $0 monthly plan premium (CMS 2027 Landscape file). What varies far more is the out of pocket maximum, the most you pay in a year for covered care in network: our analysis of the same file puts the average at $2,232 and the median at $1,500, with a range from $199 to $9,850.
