For 2027, Stockton is looking at 39 Medicare Advantage plans: 9 new, 14 gone since 2026, and 30 still here but changed on premium, deductible, plan type or name, 11 of them under a new name. Below, how the lineup shifted in San Joaquin County and what to compare, with no plan ranked or recommended.

STOCKTON, Calif. — Fall 2026. For Medicare shoppers in Stockton who are managing a long-term illness like diabetes, heart disease, chronic lung disease or kidney failure, the 2027 plan lineup includes a specific type of Medicare Advantage plan built around that diagnosis: a Chronic Condition Special Needs Plan, or C-SNP. Stockton is in San Joaquin County, where CMS data show 12 C-SNPs will be offered for 2027 from five carriers, with one brand-new plan joining the lineup and six Alignment plans carrying new names.

What is a C-SNP and how does it work in Stockton for 2027?

A Chronic Condition Special Needs Plan is a type of Medicare Advantage plan that only enrolls people who have one of the chronic conditions CMS allows the plan to serve. In San Joaquin County, 12 of the Medicare Advantage plans available for 2027 are C-SNPs. Like other Medicare Advantage plans, each one bundles Part A, Part B and (in every C-SNP offered in the county) Part D drug coverage into a single plan.

What sets a C-SNP apart is that the plan is designed around the condition itself. The drug list, care team and extra benefits are shaped for people living with that diagnosis. Because of that focus, you can only join if a provider confirms you have the qualifying condition the plan serves.

Which carriers offer C-SNPs in San Joaquin County for 2027?

Five carriers offer C-SNPs in San Joaquin County for 2027: Alignment Health Plan (6 plans), Elevance Health (Anthem) (1 plan), Imperial Health Plan of California, Inc. (2 plans), SCAN Health Plan (2 plans), and UnitedHealthcare (1 plan). The table below lists every C-SNP by name.

A few things worth noting from the 2027 data:

• Anthem Kidney Care (PPO C-SNP) from Elevance Health (Anthem) is new for 2027. Its name points to the condition it serves.
• Imperial Flex (HMO C-SNP) from Imperial Health Plan of California is also new for 2027.
• Six Alignment Health plans have been renamed for 2027 — the plans are the same type of C-SNP as before, just under new names. Alignment's lineup includes BreathEasy Plus 041, Clarity Plus 042, three Heart & Diabetes plans (010, 048, 051) and Heart & Diabetes Plus 039.
• SCAN Health Plan offers SCAN Balance and SCAN Strive. UnitedHealthcare offers UHC Complete Care Support CA-8AP. Imperial Health Plan also offers Imperial Senior Value.

To keep this fair, we are not comparing premiums, copays, drug lists, networks or star ratings here — those vary by plan and by person, and the Medicare Plan Finder at medicare.gov is the right place to look them up for your situation.

How do I know if I qualify for a C-SNP?

You qualify when a provider confirms, in writing, that you have the specific chronic condition a plan is built for. The plan will ask for that verification — often a form your doctor signs — before your enrollment is finalized. Without that confirmation, you cannot stay enrolled.

If your condition is not the one a plan is designed for, that plan is not an option even if it is offered in your ZIP code. Where a C-SNP's name points to the condition it serves (for example, Anthem Kidney Care or Alignment Health's Heart & Diabetes plans), you can usually tell at a glance whether it may fit. For plans with less specific names, call the plan or Medicare and ask which chronic condition the plan is approved to serve.

When can I enroll in a C-SNP in Stockton?

A qualifying chronic condition triggers a Special Enrollment Period, so you are not limited to the fall Annual Enrollment window. You can generally enroll in a C-SNP once your diagnosis is confirmed, and you have a one-time chance to switch or drop the C-SNP after you join.

That said, the regular Annual Enrollment Period — October 15 through December 7, 2026 — is still the main window where most people in Stockton compare plans for 2027. Changes made during that window take effect January 1, 2027. If you do nothing, your current plan renews for 2027 as described in its Annual Notice of Change (ANOC), which the plan mails in the fall.

What else is changing in Medicare for 2027?

A few program-level numbers are already set for 2027 and apply nationwide, including in Stockton:

• The Part D out-of-pocket cap rises to $2,400 in 2027 (up from $2,100 in 2026).
• The Part D maximum deductible is $700 in 2027 (up from $615 in 2026).
• The Part D national base beneficiary premium for 2027 is $41.33 — this is a formula input, not what any particular plan charges.

The 2027 standard Part B premium and deductible, and the 2027 IRMAA income brackets, had not been announced as of September 2026. CMS typically publishes those later in the fall.

In the broader San Joaquin County Medicare Advantage lineup for 2027, CMS data show 14 plans are not returning, 9 are new and 11 have been renamed. If your current plan is affected, the specifics will be in your ANOC.
