Medicare in Agua Dulce, Green Valley and 91390 by the numbers
ZIP code 91390 covers the country north of Santa Clarita. It is home to 19,308 people, and 2,928 of them are 65 or older, 15.2 percent, the same share as Los Angeles County as a whole, with a median age of 46.7 against 38.2 countywide. Those counts come from the 2020 to 2024 American Community Survey, summed from the age brackets rather than estimated from a percentage. The median household income is $151,897, and 86.6 percent of occupied homes are owner occupied, 5,556 households out of 6,414, against 45.9 percent countywide. The ZIP code contains the whole of two unincorporated communities and the northern edge of the City of Santa Clarita, and by the Census Bureau's own boundary file most of its land lies in no named place at all. Agua Dulce is home to 2,828 people, 703 of them past 65, which is 24.9 percent, with a median age of 56.8, a median household income of $146,107 and 88.9 percent of homes owner occupied, 968 of 1,089. Green Valley is home to 880, 145 of them past 65, with a median age of 51.9 and 308 of its 420 homes owner occupied. The remaining 2,080 residents past 65 live on the Santa Clarita edge and in the land between. Of residents aged 5 and over across the ZIP code, 78.6 percent speak only English at home and 13.8 percent speak Spanish; in Agua Dulce, 22.0 percent speak Spanish.
No hospital in the ZIP code, and the nearest is in Valencia
There is no hospital inside 91390. Measured from the middle of the ZIP code, the nearest by a wide margin is Henry Mayo Newhall Hospital at 23845 McBean Pkwy in Valencia, to the south, licensed for 334 beds and the general hospital for the Santa Clarita Valley. East, in the Antelope Valley, Antelope Valley Hospital at 1600 W Ave J in Lancaster is licensed for 390 beds and Palmdale Regional Medical Center at 38600 Medical Center Drive for 184, both with emergency departments. There is no Kaiser hospital in either valley; the nearest is Kaiser Foundation Hospital Panorama City at 13652 Cantara St, licensed for 218 and reachable only through a Kaiser plan. Those counts come from California state licensing records, read this month. Henry Mayo, Antelope Valley Hospital, Palmdale Regional and Kaiser are separate systems, and the plan's medical group decides which of them admits you, which out here also decides which way you drive. Medicare Advantage networks are built around medical groups rather than around the insurance company's name, so two plans carrying the same logo can reach completely different doctors, and those contracts are renegotiated year to year. Before you enroll in anything, Lara pulls each plan's current directory and confirms your doctors, your hospital and your pharmacy, and she repeats that check each fall when plans publish their changes.
The house, the drive, and the income surcharge
Agua Dulce's numbers describe an older community than the county around it: a median age of 56.8 against 38.2 countywide, a quarter of residents past 65, and nearly nine homes in ten owned. Three things follow. The first is the house: where the home is the family's largest asset, how long term care would be paid for and how a home is treated under Medi-Cal's rules belongs in the same conversation as the plan, not one years later. The second is the drive. A plan's medical group decides whether your hospital is Henry Mayo in Valencia or one of the Antelope Valley hospitals to the east, and that is a real difference in miles; home health aides and in home services are also harder to arrange this far out, so it is worth checking which agencies a plan's network actually sends before you need one. The third is money. On household incomes around one hundred and fifty thousand, the income surcharge on Part B and Part D premiums often applies, and because it is set from the tax return of two years earlier, a first year of retirement is so often overcharged; Form SSA-44 exists to correct it after a life changing event such as retirement. Original Medicare with a Medicare Supplement works with any doctor or hospital in the country that takes Medicare, which is why it deserves a real comparison here rather than being assumed away. Across the county's general enrollment Medicare Advantage plans, out of pocket maximums run from $199 to $9,250 in 2026, and the Part D cap is $2,100.
Medicare Advantage in Agua Dulce and Green Valley by the numbers, 2026
Agua Dulce and Green Valley sit in Los Angeles County, one of the biggest Medicare Advantage markets in the country. In 2026 the county has 74 Medicare Advantage plans open to general enrollment plus 47 Special Needs Plans, per the CMS 2026 Landscape file, and 65 of those 74 plans charge a $0 monthly plan premium. About 57 percent of the county's 1.7 million Medicare beneficiaries are enrolled in Medicare Advantage or other Medicare health plans (CMS, May 2026). Our analysis of the same CMS file puts the average in network out of pocket maximum across the county's general enrollment plans at $2,428, with a median of $1,700 and a range from $199 all the way to $9,250. That spread is the whole argument for comparing before you enroll: two $0 premium plans can differ by thousands of dollars in a bad year.

Straight answers, and the fine print up front
Here is exactly how this works. Lara is a licensed independent insurance agent, and her help costs you nothing, because licensed agents are paid by the insurance companies whose plans they represent. Your premium is the same whether you enroll through an agent, online, or directly with the insurer. What an independent agent adds is the comparison: she is appointed with several carriers rather than one. She does not carry every plan available in Los Angeles County, and she will tell you when something she cannot sell looks like the better fit for you.
