Our Extra Help and Medi-Medi dual eligibility guide explains what it means to qualify for both Medicare and Medi-Cal at once. This guide goes a step further and focuses specifically on D-SNP plans: how they work under the hood, what extra benefits they offer that a regular Medicare Advantage plan does not, and how to choose the best D-SNP plan available in your Southern California county.
How D-SNP plans work under the hood
A D-SNP (Dual Eligible Special Needs Plan) is a Medicare Advantage plan with a special contract that only people with dual eligibility can use. Unlike a regular Advantage plan, a D-SNP is designed to coordinate with your Medi-Cal plan, not just with Medicare, which in theory should simplify care between both programs instead of treating them as separate systems.
In California, some D-SNPs are 'aligned' with your Medi-Cal plan, meaning the same insurer manages both benefits, generally with a single card and a single customer service number. Others are 'non-aligned,' pairing one company for Medicare with a different one for Medi-Cal. An aligned plan usually means less confusion about who to call and smoother care coordination between your providers.
Each D-SNP plan assigns members a care coordinator or case manager, whose job is to help you schedule appointments, understand your benefits, and connect medical services with the social supports Medi-Cal may cover, such as non-medical transportation or in-home services.
The extra benefits a D-SNP offers
Beyond standard medical and drug coverage, most D-SNP plans include extra benefits designed specifically for this population's needs: non-emergency transportation to medical appointments and the pharmacy, delivered meals for a period following a hospital stay, and a prepaid benefits card for over-the-counter (OTC) products like vitamins, hygiene items, and pain relievers.
Many plans also add broader dental coverage than a standard Advantage plan, vision exams with an allowance toward glasses, discounted hearing aids, and wellness programs like gym memberships. The exact catalog of extra benefits, and the dollar amount on the OTC card, varies quite a bit from plan to plan, so it is worth comparing each one in detail rather than assuming they all offer the same thing.
Availability, cost, benefits, and eligibility vary by person, product, contract, and insurance company, as well as by your service area. Guarantees are subject to the claims-paying ability of the issuing insurance company. Karla Arámburo is not affiliated with or endorsed by Medicare or the federal government.
Most D-SNP plans also conduct a Health Risk Assessment within the first few months of your enrollment and, generally, once a year after that. This assessment helps the plan identify your specific medical and social needs — such as mobility issues, food access, or social isolation — in order to connect those findings with the right extra benefits, rather than waiting for you to request them on your own.
How to qualify for a D-SNP plan
To qualify for a D-SNP you need to have Medicare (Part A and Part B) and some level of Medi-Cal at the same time. There are different categories of dual eligibility: 'full duals' receive all Medi-Cal benefits, while 'partial duals' only receive Medi-Cal help with Medicare premiums and cost-sharing, without full Medi-Cal coverage.
Some D-SNP plans accept both full and partial duals, while others are limited to a single category, so it is worth verifying which applies to your situation before choosing a specific plan. If you are unsure of your eligibility category, we can review it together by comparing your Medi-Cal notice against the plan's requirements.
The Special Enrollment Period for dual eligibility
Unlike most people with Medicare, who can only switch Medicare Advantage plans during the Annual Enrollment Period from October through December or the Medicare Advantage Open Enrollment Period from January through March, people with dual eligibility generally have a Special Enrollment Period that lets them switch D-SNP plans once per quarter during the first nine months of the year.
This extra flexibility is valuable if your eligibility situation changes mid-year, if you move to a county with different plan options, or if you discover your current plan is not properly aligned with your Medi-Cal coverage. Even so, switching plans too frequently can disrupt continuity with your doctor and care coordinator, so it is worth comparing carefully before deciding on a change, even when the rule allows you to make one.
How to choose a D-SNP plan in Southern California
D-SNP plan availability varies by county: the options in Orange, Los Angeles, San Diego, and Riverside counties are not always the same, and some counties have more aligned plans available than others. Before choosing, confirm whether your current doctors, preferred hospital, and pharmacy are within the network of the plan you are considering.
Also compare each plan's Medicare star rating, which reflects service quality and member satisfaction, and carefully review the specific catalog of extra benefits — transportation, meals, the OTC card, dental — because those differences can matter just as much as the medical network itself when choosing.
Also keep continuity of care in mind if you switch D-SNP plans: most insurers must temporarily honor treatments already in progress — such as chemotherapy or physical therapy already scheduled — during a transition period even if your provider is not in the new network, while you work with the new plan to find an in-network provider for the long term.

Finally, do not assume the most heavily advertised D-SNP plan on television is automatically the best one for you. The right coverage depends on your current doctor network, your specific medications, and which extra benefits you will actually use, not just the insurer's name or how much it spends on advertising.
Frequently asked questions
What does D-SNP stand for?
D-SNP stands for Dual Eligible Special Needs Plan, a type of Medicare Advantage plan built exclusively for people who qualify for both Medicare and Medicaid (Medi-Cal in California) at the same time.
Do I need to pay a premium for a D-SNP plan?
Most D-SNP plans charge no additional monthly premium for those who qualify, since Medi-Cal generally covers the Part B premium and other cost-sharing. Even so, it is always worth confirming the exact details of each plan before enrolling.
What is the difference between an aligned and a non-aligned D-SNP?
An 'aligned' D-SNP belongs to the same company that manages your Medi-Cal plan, which usually means a single card, a single customer service number, and simpler coordination between both benefits. A non-aligned D-SNP pairs two different companies for Medicare and Medi-Cal, which can complicate care coordination.
If I lose Medi-Cal, do I automatically lose my D-SNP plan?
Not right away. Most D-SNP plans provide a grace period of several months for you to resolve your Medi-Cal eligibility before being moved to a regular Medicare Advantage plan or Original Medicare. It is important to act quickly if you receive a notice that your eligibility is under review.
Do D-SNP plans include drug coverage?
Yes. D-SNP plans are MA-PD plans, meaning they include Part D drug coverage within the same plan, and most members also qualify for Extra Help, which further reduces their prescription costs.
Can I switch D-SNP plans at any time of year?
Yes, in most cases. People with dual eligibility generally have a Special Enrollment Period that allows them to switch Medicare Advantage or D-SNP plans once per quarter during the first three quarters of the year, in addition to the Annual Enrollment Period from October through December.
How do I choose between several D-SNP plans available in my county?
Compare whether the plan is aligned with your Medi-Cal plan, whether your doctors and preferred hospital are in-network, which extra benefits each one offers (transportation, meals, OTC card), and its Medicare star rating. We can compare these options together based on your county.
