What is CBAS, and could it be the program your family has been searching for?
You are at the kitchen table. It is late. You have one browser tab open for nursing homes, another for in-home care agencies, and a third for something a cousin mentioned called IHSS. You are exhausted. And you have not yet found the thing you actually need.
For many California families, the thing they actually need has a name almost nobody hears until a hospital discharge planner says it out loud. The name is CBAS. It stands for Community Based Adult Services, and it is a Medi-Cal benefit that quietly keeps tens of thousands of older and disabled adults safely cared for during the day while their families keep working, keep parenting, and keep their household intact.
This guide is the long form companion to Episode 5 of the California Care Compass podcast. It walks through what CBAS is, who qualifies, who pays, how the authorization process actually works, what a day at a center looks like, and how CBAS fits with other California programs like In Home Supportive Services and the Assisted Living Waiver. If you came here from the episode, the audio is the conversation. This page is the checklist.
What CBAS actually is, in plain language
CBAS stands for Community Based Adult Services. It is a licensed day health program for adults who need a meaningful level of care during the daytime hours. The California Department of Health Care Services (DHCS), which administers Medi-Cal, defines CBAS as a structured outpatient program of clinical and personal services delivered at a licensed center, with participants returning home at the end of each day.
A CBAS center is not a senior center, and the distinction matters. A senior center is a community gathering place. A CBAS center is a licensed health facility that happens to send people home in the afternoon. CBAS centers, which California previously regulated under the older name Adult Day Health Care, are required to staff a registered nurse, a physical therapist, an occupational therapist, a speech therapist, a social worker, and a program director. They employ personal care aides. They serve hot meals, administer medications, and in most cases provide door to door transportation.
The Centers for Medicare and Medicaid Services (CMS) approves CBAS as a Medi-Cal state plan benefit. That means California is required, under federal Medicaid rules and the terms of the program's settlement history, to make CBAS available to members who meet the eligibility criteria. The participant's Medi-Cal managed care plan pays the center for the days of authorized service. The family, in most cases, does not see a bill.
That last fact is why CBAS is one of the most consequential and least known programs in California's long term care landscape. The cost figures live on the California Care Compass data page, where we keep them current. What you need to know walking in is that CBAS is a covered benefit for Medi-Cal members who qualify.
Who CBAS is for, and how to know if your parent fits
The simplest way to describe the CBAS population is this. CBAS is for adults who need more than companionship and less than a nursing home.
DHCS sets the eligibility rules. A participant generally must be enrolled in Medi-Cal, be at least eighteen years old, and meet what the state calls nursing facility level of care criteria. That phrase sounds bureaucratic, and it is, but the practical translation is that the participant has medical, cognitive, or functional needs significant enough that, without daytime support, they would be at meaningful risk of harm, hospitalization, or institutional placement.
What that looks like at home
At the kitchen table, the CBAS profile usually looks like one of a few patterns.
- A parent with moderate Alzheimer's or another dementia, who can still walk, eat, and recognize family, but who cannot be left alone safely during the day because of wandering, kitchen safety issues, or vulnerability to scams.
- A parent recovering from a stroke, who needs more therapy than outpatient rehabilitation provides, and who is becoming depressed sitting at home alone.
- An adult child with a developmental disability and a complex medical condition like diabetes, whose aging parents can no longer manage daytime supervision, medication, and meals.
- An older adult with congestive heart failure, COPD, or another chronic condition that requires daily clinical monitoring to prevent repeat hospitalizations.
In each of these cases, the value CBAS adds is that there are clinical eyes on the participant every day. The nurse is checking vitals and watching for changes. The therapist is doing the work that maintains function. The social worker is watching for shifts in mood, weight, family situation, and home safety. The family is freed to keep working, keep sleeping, and keep being a family.
CBAS is not the right fit for everyone. A fully independent older adult who is simply lonely is better served by a county senior center or by the California Department of Aging (CDA) network of community programs. An adult who requires twenty four hour supervision and cannot be safely at home overnight is in a different conversation, often involving the Assisted Living Waiver or skilled nursing. CBAS lives in the middle of that spectrum, which is where most California families discover they are standing.
Who pays for CBAS, and where the program comes from
CBAS is a Medi-Cal benefit. Medi-Cal is California's implementation of the federal Medicaid program, jointly funded by the state and the federal government. DHCS administers Medi-Cal in California, and CMS approves the program structure at the federal level.
The history matters because it explains why CBAS has the legal protections it has today. In 2011, during a budget crisis, California moved to eliminate Adult Day Health Care as a Medi-Cal benefit. Disability rights advocates, with support from organizations including Disability Rights California and Justice in Aging, filed suit. The settlement in 2012, known as Darling v. Douglas, created CBAS as the successor program with stronger eligibility protections and a delivery structure rooted in Medi-Cal managed care. Justice in Aging continues to publish guidance on CBAS rights and access, and that guidance is one of the most useful resources for families who hit an authorization roadblock.
In practice, three parties sit at the table. The first is the participant, your family member. The second is the CBAS center, a state licensed provider. The third is the Medi-Cal managed care plan in which the participant is enrolled. The plan authorizes the number of CBAS days per week. The center delivers the care. DHCS pays the plan. CMS funds the federal share.
If your family member is on fee for service Medi-Cal rather than a managed care plan, which is less common in 2026 but still occurs in certain populations, the authorization route is different and runs more directly through DHCS. In either case, the CBAS center handles most of the paperwork. The family's job is to find the right center and ask the intake coordinator to begin the process.
How families actually get a CBAS spot
This is the section most families need, because the process is not intuitive and the system does not push it toward you. Move through these steps in order, and do not skip the tour.
Step one, find the centers near you
DHCS maintains a list of licensed CBAS centers organized by county. Search by the participant's home zip code, because transportation matters. Most centers serve a defined radius, and if the participant lives outside that radius, the van will not come. The county Area Agency on Aging, part of the network coordinated by the California Department of Aging, can also help identify nearby centers.
Step two, call the centers
Call two or three centers from your short list. You are not committing to anything. You are asking three questions. Do you accept my family member's Medi-Cal managed care plan. Do you currently have openings. Can we come tour. The person who answers is usually the intake coordinator or the on staff social worker, and helping families like yours is their job.
Step three, tour the building
Go in person. Bring your family member if they are willing and able. Walk the building. Watch a meal. Watch an activity. Notice whether staff make eye contact with participants, use participants' names, and respond to participant requests with patience. Notice whether the building smells clean. Notice whether participants look engaged or whether they look parked. The cues are similar to the cues you would look for at a preschool. Warmth and competence.
Step four, complete the assessment
If the center believes your family member may qualify, the center will initiate a formal assessment. A registered nurse from the center will conduct a face to face evaluation that covers medical history, current diagnoses, medications, functional ability, cognitive status, and home environment. The result is a document called an individual plan of care, which the center submits to the participant's Medi-Cal managed care plan for authorization.
Step five, wait for the authorization
The Medi-Cal managed care plan reviews the documentation and authorizes a specific number of CBAS days per week. Many participants begin at three days. Some are authorized up to five. The number of days reflects clinical need, not family preference. If the plan delays or denies, ask the center to help you respond. Justice in Aging has published detailed guidance on appealing CBAS denials, and the appeal pathway is well established.
Step six, begin attendance
Once authorized, the center schedules a start date and sets up transportation. Most centers, especially those serving participants with dementia, use a gradual onboarding, with shorter first days and a slow introduction to activities. The full process, from first phone call to first day, can take anywhere from a couple of weeks to a couple of months. Push gently. Document every call. If you do not hear back from the plan in a reasonable window, call the plan's member services line and request the status of the CBAS authorization.
What a day at a CBAS center actually looks like
It is worth describing the day in detail, because the picture is usually what moves a family from researching CBAS to enrolling.
The morning begins with the van. The driver knows the route and knows the participant. The van picks up three or four participants on a loop and arrives at the center by mid morning. A staff member greets each participant at the door, helps with the coat, and walks them into the main room. The nurse performs a brief check in, takes vitals if those are part of the care plan, and administers any scheduled morning medications.
The morning programming is structured. Chair exercise led by a staff member, calibrated to the group's mobility. Memory care activities for participants with dementia, designed for their cognitive level without being infantilizing. Physical therapy or occupational therapy sessions in a side room for participants whose plan of care includes those services. Speech therapy where indicated.
Lunch is hot, served family style or restaurant style depending on the center. Kitchens accommodate medical diets, including diabetic, low sodium, renal, and pureed diets. Centers also accommodate cultural diets, which matters enormously in a state as diverse as California. In Los Angeles County, families will find CBAS centers built around Korean, Persian, Armenian, Mandarin, Spanish, and Tagalog speaking communities. In the Central Valley, families will find centers serving Punjabi, Hmong, and Mexican American communities. In the Bay Area, families will find Cantonese, Vietnamese, and Russian speaking centers. This is not incidental. CBAS only works when participants feel at home.
After lunch comes a rest period for participants who need it. Recliners, a quiet room, low light. Then the afternoon programming resumes. Crafts, music, visiting performers, a chaplain in centers that offer pastoral care. The social worker moves through the room, checking in with participants whose family situation is shifting, watching for the participant who has suddenly withdrawn or lost weight.
By mid afternoon, the nurse administers afternoon medications. Aides assist with toileting, grooming, and preparation for the ride home. The van pulls up. Participants are loaded back on. By late afternoon the participant is home, fed, medicated, exercised, and seen.
The family member who has been at work has had a normal day. No emergency call from a neighbor. No frantic drive across town. The participant comes home tired in a good way, ready to tell the family at dinner about the woman she sat next to at lunch. That is what CBAS delivers. Not a miracle. A structured, licensed, clinically supervised day, repeated three to five times a week, that allows a California family to stay together at home for years longer than would otherwise be possible.
How CBAS fits with IHSS, Medicare, PACE, and the rest of the stack
California families almost never use a single program. They build a stack, and CBAS plays well inside that stack.
CBAS and In Home Supportive Services
In Home Supportive Services (IHSS) is administered by the California Department of Social Services (CDSS) and delivered at the county level. IHSS pays a caregiver, frequently a family member, to provide personal care in the home. A participant can receive both IHSS and CBAS at the same time. The CBAS center covers the daytime hours the participant is in attendance. IHSS covers mornings before pickup, afternoons after drop off, evenings, weekends, and any days the participant is not at the center. The county IHSS social worker who conducts the home assessment will ask about CBAS attendance, because the two programs coordinate hours. A participant attending CBAS three days a week needs fewer IHSS hours on those days and more on the other days. This is normal coordination, not a conflict.
CBAS and Medicare
Medicare does not pay for CBAS. Medicare, administered by the Centers for Medicare and Medicaid Services, covers medical care, hospital stays, doctor visits, short term skilled nursing after a qualifying hospitalization, and limited home health. CBAS is custodial and long term in nature, which puts it in the Medi-Cal lane rather than the Medicare lane. For dual eligible participants, those enrolled in both Medicare and Medi-Cal, Medi-Cal pays for CBAS while Medicare continues to cover physician visits, hospitalizations, and other acute care.
CBAS and PACE
The Program of All Inclusive Care for the Elderly (PACE) is not CBAS, but it overlaps. PACE is a fully integrated managed care program that bundles a day center, medical care, prescription drugs, and home support into a single plan for participants who are at least fifty five years old and meet nursing facility level of care criteria. PACE is approved by CMS and administered in California with DHCS oversight. In communities where a PACE program exists, PACE may be the right answer instead of CBAS, because PACE assumes responsibility for all of the participant's care. CBAS, by contrast, is a benefit that sits alongside the participant's existing primary care, Medi-Cal managed care plan, and other supports. If a social worker raises PACE, take the meeting.
CBAS and the Assisted Living Waiver
The Assisted Living Waiver, also administered by DHCS, is a separate Medi-Cal program that pays for the care component of assisted living for eligible participants in specific California counties. The Assisted Living Waiver is for participants for whom home is no longer workable but a nursing home is not the right placement. CBAS and the Assisted Living Waiver address different points in the care journey. CBAS supports participants who still live at home. The Assisted Living Waiver supports participants who have moved into a licensed Residential Care Facility for the Elderly.
What if my parent does not speak English, has dementia, or has behavioral needs
CBAS centers are built for exactly these situations, and walking in with these questions is the right way to start the conversation.
Language access
California licenses CBAS centers in communities where the staff, the meals, the activities, and the social work are delivered in the language of the community. Families can find centers operating in Mandarin, Cantonese, Russian, Farsi, Arabic, Korean, Vietnamese, Tagalog, Spanish, Armenian, Punjabi, Hmong, and many other languages. When calling a center, ask about staff languages and the language of programming. If the closest center is not a language match, ask the intake coordinator to refer you to a center that is.
Dementia care
Most CBAS centers serve a high proportion of participants with dementia, and many have specialized memory care programming, secure perimeters to prevent unsafe exits, and staff trained in dementia care techniques. The intake assessment will consider whether the participant's stage of dementia is appropriate for the day program setting. There is a point at which the participant's needs exceed what a day program can safely manage, and a responsible center will say so directly rather than enroll a participant who cannot be served safely.
Behavioral needs
Centers can support participants with anxiety, depression, mild behavioral disturbance, and the agitation often associated with dementia. Centers cannot safely manage participants who are physically aggressive in ways that endanger other participants or staff. If your family member has had behavioral incidents, share that history during the assessment. Hiding it serves no one. Naming it allows the center to evaluate fit honestly and, if needed, refer the family to a higher level of care.
What to do this week
If you have read this far, you are likely considering whether CBAS could fit someone in your family. Here is a seven day action plan.
- Confirm Medi-Cal status. If your family member has Medi-Cal, identify the managed care plan. The card will show it, or the county Medi-Cal office can confirm. If they do not have Medi-Cal but may qualify, start the application through BenefitsCal or your county social services office. Medi-Cal eligibility is the gate to CBAS.
- Find the CBAS centers within driving distance of where your family member lives. Use the DHCS provider list and the county Area Agency on Aging. Build a short list of two or three.
- Call each center. Ask if they accept the Medi-Cal plan. Ask about openings. Schedule a tour.
- Tour at least one center. Bring your family member if possible. Trust your read on warmth and competence.
- If the tour goes well, ask the center to initiate the assessment. The center will guide you through paperwork. The hardest part was the first phone call, and you will have already made it.
- While the authorization is pending, keep current supports in place. Do not cancel home health, do not reduce IHSS hours, and do not make irreversible decisions before CBAS is actually approved and started.

The California Care Compass editorial take
CBAS is one of the most consequential and least publicized programs in California's long term care system. It is a real Medi-Cal benefit, administered by the California Department of Health Care Services, approved by the Centers for Medicare and Medicaid Services, and protected by a court settlement that disability rights advocates fought to win. It accomplishes exactly what most working California families need. It keeps an older adult or a disabled adult safely cared for during the day, in a clinically supervised setting, while the family keeps working and the participant keeps living at home.
The reason families do not hear about CBAS until a hospital social worker happens to mention it is not the families' fault. It is a communication failure inside the system itself. The program is strong. The outreach is thin. Part of why California Care Compass exists is to close that gap, episode by episode, page by page, so that the daughter at her kitchen table at eleven at night, searching for the thing that will let her keep her mother at home, finds the answer faster.
A few honest caveats. CBAS center density is uneven across the state. Rural California has fewer centers than urban California, and the transportation radius is a real constraint. Authorization timelines vary by managed care plan, and some families receive an initial denial and have to appeal. None of that should stop you from making the first call. The program is worth the effort, the strong centers will help you navigate the authorization, and organizations including Justice in Aging publish appeal guidance for families who hit a wall. If you are at the kitchen table tonight, take a breath. You have already done the hardest part, which was looking. Tomorrow, make one phone call. One call to one CBAS center near your parent. That is the step that matters.
