SDP vs IHSS vs Medi-Cal Waivers: A California Family Guide

For many California families, the hardest part of caring for a loved one with a developmental disability is not the caregiving itself. It is the alphabet. IHSS. HCBS. Medi-Cal. And the Self-Determination Program, or SDP, California's option that lets families direct their own budget and choose their own providers. Each program has its own name, its own office, and its own set of rules. Almost no one hands you a single map that shows how the pieces connect.

If you have felt that confusion, you are not behind and you are not doing anything wrong. These programs grew up separately, so the overlap between them was never designed to be obvious. This guide is that missing map. It walks through what each program is for, how they fit together, and where a Self-Determination Program budget asks a little more of you in exchange for a great deal more choice.

Why This Matters

When families do not understand how these programs relate, two things tend to happen. Some families choose one program and quietly leave real support on the table, never realizing they qualified for another at the same time. Others assume the programs compete, and they spend months agonizing over a decision that was never really an either-or.

Getting the lay of the land early saves you both. It helps you understand what each program can fund, who decides your eligibility, and how the programs can work side by side rather than against each other.

Start With What Each Program Is For

The clearest way to untangle these three is to stop thinking of them as rivals and start thinking of them as tools with different jobs.

In-Home Supportive Services (IHSS)

In-Home Supportive Services is a Medi-Cal program run by your county. Its job is to help someone remain safely at home by paying for personal care and related help, such as assistance with bathing, meal preparation, and household tasks. In many families, the paid caregiver is a relative.

IHSS is available to eligible Medi-Cal recipients who are older adults or who have a disability, and your county social services office decides eligibility and authorized hours. You do not need a developmental disability to qualify for IHSS. That is one reason it reaches so many California families.

Medi-Cal Home and Community-Based Services (HCBS) Waivers

Medi-Cal Home and Community-Based Services waivers are less a single program and more the funding structure that makes home-based support possible. Their job is to let Californians receive care in their own homes and communities instead of in an institution.

For individuals with developmental disabilities, these waivers fund the services coordinated through your Regional Center. You can read more about how the state describes them on the California Department of Health Care Services Medi-Cal Waivers page.

The Self-Determination Program (SDP)

The Self-Determination Program is a self-directed way to receive Regional Center services. Instead of the Regional Center arranging vendors and services for you, you receive an individual budget, and you choose the providers who deliver your loved one's support. If SDP is new to you, our overview of what the Self-Determination Program is and how it works in California is a good place to start.

SDP is not a separate world from Medi-Cal. It is delivered through its own Medi-Cal waiver, so when a family enrolls in SDP, they move from the traditional Regional Center waiver to the SDP waiver. Because you are directing money and paying providers, SDP requires a Financial Management Services (FMS) provider to handle payroll, vendor payments, and budget tracking on your behalf. The official overview lives on the California Department of Developmental Services SDP page.

How the Three Fit Together (Not an Either-Or)

Here is the part that surprises most families: these programs are not three doors where you pick one and walk away from the rest.

Many families use more than one at the same time. IHSS very often continues right alongside the Self-Determination Program. In fact, SDP asks participants to use available generic resources, such as IHSS and Medi-Cal state plan benefits, before spending their SDP budget. The logic is simple. Your individual budget is not meant to pay for something another program already covers, so using those resources first stretches your SDP dollars further.

And because the Self-Determination Program is itself a Medi-Cal waiver, choosing SDP is really choosing how you receive your Regional Center services, self-directed rather than traditional. It is not a decision to leave Medi-Cal behind.

A useful way to hold it in your head:

• IHSS pays for in-home personal care, through your county.

• Medi-Cal HCBS waivers are the framework that funds community-based services, including your Regional Center supports.

• SDP is the self-directed path within that framework, where you hold the budget and pick your providers.

Because eligibility rules and how programs coordinate can vary by county and Regional Center, your Service Coordinator and your county IHSS office are the right people to confirm what your family qualifies for. When in doubt, ask both.

Where the Self-Determination Program Asks More of You (and Gives More Back)

If IHSS and traditional Regional Center services mostly ask you to receive support, the Self-Determination Program asks you to direct it. That is the trade. You gain real choice and flexibility, and in return you take on the role of decision-maker for your budget. If you are weighing that shift, our guide on SDP vs traditional Regional Center services walks through the decision in more detail.

Two roles exist to support you in that work, and families often confuse them, so it is worth being precise. The Financial Management Services provider is mandatory in SDP. Every participant must have one, because someone has to pay employees legally, pay vendors, and keep the budget reconciled. The Independent Facilitator is optional but strongly recommended. An Independent Facilitator helps you plan and navigate the program, but you are not required to use one.

Funding for an Independent Facilitator comes in two phases, which is another common point of confusion. During the transition into SDP, the Regional Center covers Independent Facilitator support, currently up to $2,500, including a fixed $1,000 fee for the Person-Centered Plan and up to 40 hours of additional transition help. Once you are up and running, any ongoing Independent Facilitator support is paid from your individual SDP budget rather than from a separate Regional Center allowance.

The reward for taking on this direction is meaningful. With traditional FMS providers, many families use only 60 to 70 percent of their approved budget, because the tools make it hard to see where the money is going until it is too late. Families with real-time visibility routinely reach 95 percent or more. The difference is not a harder-working family. It is better information.

How Accura FMS Makes This Easier

When you are holding three programs in your head, the last thing you need is a Financial Management Services provider that adds to the fog. This is where Accura FMS was built to help.

Accura is technology-enabled and human-led. When you call, you reach a Customer Success Manager who actually knows the Self-Determination Program, usually within a minute, not a general call center representative reading from a script. Emails are answered the same day. For a family still sorting out where IHSS ends and SDP begins, having an SDP expert who picks up the phone is worth more than any feature list.

Behind that human support is a modern portal that shows your budget in real time, pays vendor invoices in days rather than the weeks or months common with traditional providers, and lets you see exactly where your funds stand. You keep the choice and control the program promises, without the spreadsheet-and-guesswork burden that leaves so many budgets underused.

Frequently Asked Questions

Can I have both IHSS and SDP at the same time?

In most cases, yes. IHSS commonly continues alongside the Self-Determination Program, and SDP participants are generally expected to use generic resources like IHSS before spending their individual budget. Your county IHSS office and your Regional Center Service Coordinator can confirm how the two coordinate for your family.

Is SDP a Medi-Cal program?

Yes. The Self-Determination Program is delivered through a Medi-Cal Home and Community-Based Services waiver. Enrolling in SDP means moving to the SDP waiver, not leaving Medi-Cal.

Do I need a Financial Management Services provider for IHSS too?

No. An FMS is specific to the Self-Determination Program, where you direct a budget and pay providers. IHSS is administered through your county, so it does not require an FMS. In SDP, an FMS is mandatory.

Which program should my family choose?

That depends on your loved one's needs, eligibility, and goals, and it is often not a single choice at all. Because these programs can work together, the better question is usually which combination fits. A qualified professional, your Service Coordinator, or your county can help you decide.

Does SDP replace my Regional Center?

No. Your Regional Center stays involved. SDP simply changes how you receive Regional Center services, giving you a budget to direct rather than services the Regional Center arranges for you.
