Medi-Cal MSSP Waiver in San Diego: Eligibility, Application, and What It Covers

Quick Answer

The Medi-Cal MSSP waiver (Multipurpose Senior Services Program) helps low-income seniors in San Diego remain in their homes or community settings instead of entering a nursing facility. It bundles care coordination, in-home support, adult day health, and other services under a single Medi-Cal benefit. If you or a loved one is 65 or older, qualifies for Medi-Cal, and needs nursing-facility-level care, MSSP may be the bridge that keeps independent living possible.

Key Takeaways

• MSSP is a Medi-Cal Home and Community-Based Services (HCBS) waiver — not a separate insurance plan.
• Participants must be 65 or older and require a nursing facility level of care.
• The program is available throughout San Diego County through designated local agencies.
• MSSP covers care management, transportation, respite, personal care, and more — at little or no cost to enrollees.
• Enrollment involves an assessment and is managed by an MSSP site agency; waitlists may apply.
• It works alongside — but is distinct from — programs like the California Assisted Living Waiver (ALW).

What Is the Medi-Cal MSSP Waiver?

The Multipurpose Senior Services Program (MSSP) is a California-only Medicaid waiver authorized under Section 1915(c) of the Social Security Act. The California Department of Aging (CDA) administers it statewide, but services are delivered locally through site agencies — in San Diego, that means organizations like the Aging & Independence Services (AIS) division of the County of San Diego Health and Human Services Agency.

Plain-language version: MSSP pays for the wrap-around support an older adult needs to stay safely at home when they would otherwise require a nursing home.

It is not the same as Medi-Cal In-Home Supportive Services (IHSS), though participants may receive both. And it differs from the ALW, which is specifically designed to fund assisted living costs.

The San Diego MSSP Landscape

Who Manages MSSP Locally?

In San Diego County, the primary MSSP site agency is Aging & Independence Services (AIS), part of the County's Health and Human Services Agency. AIS conducts intake screenings, arranges assessments, and assigns care managers who coordinate the full scope of MSSP services.

• Online referrals available through the San Diego County HHSA portal

How Widespread Is the Program?

MSSP operates in all 58 California counties, but capacity is limited. San Diego has historically maintained active enrollment, though waitlists do occur during periods of high demand. The county's large senior population — over 350,000 residents age 65+ — means the program is well-known to local social workers, hospital discharge planners, and elder law attorneys.

How MSSP Fits Into San Diego's Broader Senior Care System

San Diego offers a rich continuum of senior support. MSSP occupies a specific niche: it targets seniors who could go to a nursing home but prefer to stay in the community with intensive care coordination. For families weighing the full range of options — from in-home care to assisted living — the San Diego Senior Living: Options, Costs & Resources guide provides helpful context.

Eligibility Requirements

Core Criteria

To qualify for MSSP in San Diego, an applicant must meet all of the following:

1. Age: 65 years or older
2. Medi-Cal: Currently enrolled in full-scope Medi-Cal (not just emergency Medi-Cal)
3. Level of care: Assessed as requiring nursing facility level of care
4. Residence: Living in the community — a private home, apartment, board-and-care home, or other non-institutional setting
5. Willingness to participate: The individual (and/or their representative) must consent to the care management model

What "Nursing Facility Level of Care" Means

A trained assessor uses a standardized tool — typically the Minimum Data Set-Home Care (MDS-HC) — to evaluate functional limitations in activities of daily living (ADLs), cognitive status, and medical complexity. You do not have to be in a nursing home to qualify; you simply must need that level of support.

Who Does NOT Qualify

• Individuals under 65 (different waiver programs apply)
• Seniors in acute hospital care or a skilled nursing facility at the time of enrollment
• Those enrolled in PACE (Program of All-inclusive Care for the Elderly) — PACE and MSSP cannot be combined
• Individuals who do not have Medi-Cal or who have Medi-Cal only for a specific limited benefit

What MSSP Covers

MSSP is intentionally flexible. The care manager builds an individualized service plan based on the participant's assessed needs. Covered services commonly include:

Important: MSSP does not pay for nursing home care itself, room and board in assisted living, or medical services already covered under standard Medi-Cal.

Costs & Pricing

What Does MSSP Cost Participants?

For most enrollees, MSSP services are provided at no direct cost. Because it is a Medi-Cal waiver, the federal-state funding partnership covers the approved services in your care plan. There are no premiums and no copays for waiver services.

Income and Asset Limits

MSSP eligibility is tied to Medi-Cal eligibility:

• Income: Must meet Medi-Cal income thresholds (in 2024, roughly 138% of the Federal Poverty Level for many adults, though spousal protections and spend-down rules can affect this)
• Assets: California has eliminated the Medi-Cal asset test for most individuals as of January 2024, making it significantly easier to qualify

Are There Costs for Non-Covered Services?

If a participant wants services beyond what MSSP authorizes in their care plan, those costs are out-of-pocket or covered through other programs.

The Application Process

Step 1: Initial Contact

Call San Diego AIS at (800) 510-2020 or ask a hospital social worker, physician, or elder care attorney to make a referral. AIS will conduct a brief phone screening to determine if MSSP is likely the right fit.

Step 2: In-Home Assessment

An AIS assessor visits the applicant's home to complete the full functional and medical assessment. This typically takes 1–2 hours and involves the senior, family members, and any current caregivers.

Step 3: Care Plan Development

If eligible, a care manager works with the individual and family to build a written care plan. This plan identifies which MSSP services will be authorized, frequency, and providers.

Step 4: Enrollment and Service Start

Once the care plan is approved, services begin — often within 2–4 weeks of the initial assessment, barring waitlist delays.

Step 5: Ongoing Monitoring

Care managers conduct regular check-ins (at minimum monthly by phone, quarterly in-person) and revise the care plan as needs change.

MSSP vs. Other Medi-Cal Programs

If your family is evaluating whether an assisted living facility is the better path, the California Assisted Living Waiver (ALW) may be the more relevant program to explore.
