What is CBAS and how is it different from regular adult day care?

CBAS, Community Based Adult Services, is a Medi-Cal program that delivers medical-model adult day health care. A CBAS center has a registered nurse, physical and occupational therapists, a social worker, and a dietitian on staff. A regular social-model adult day program offers supervision, activities, and meals but no clinical services. CBAS is free to eligible Medi-Cal members. Social-model programs are private-pay at $20 to $30 per hour or $80 to $150 per day in most of California.

Does Medicare cover adult day care?

Original Medicare does not. Some Medicare Advantage plans offer limited day-care benefits as a supplemental, often capped at a small dollar amount per year or framed as a respite benefit. Check the specific plan's Evidence of Coverage. The reliable answer for most California families is that day care comes through CBAS (if Medi-Cal eligible) or out of pocket.

Where are CBAS centers located in California?

There are roughly 250 licensed CBAS centers across California, concentrated in Los Angeles, San Francisco Bay Area, San Diego, and the Central Valley. The California Association for Adult Day Services maintains a current directory. Rural counties have fewer centers, and transportation distance is sometimes a limiting factor. The CBAS benefit covers door-to-door transportation, which makes attendance possible even when the family cannot drive.

What does a typical CBAS day look like?

Transportation picks up the member between 7:30 and 9:00 a.m. The day at the center runs roughly 9:30 a.m. to 2:30 p.m. and includes breakfast, structured activities (cognitive games, light exercise, music, art), a nursing check, any scheduled therapy, lunch, an afternoon activity, and transportation home by 3:30 or 4:00 p.m. The member is monitored for medication adherence, vital signs, hydration, and behavioral changes throughout the day.

Can CBAS substitute for memory care?

For many families, yes, for a period. A senior with moderate dementia who lives with an adult child can often be safely supported through CBAS three to five days a week plus IHSS for personal care at home, instead of moving to a memory-care residence. The combination costs the family nothing if Medi-Cal eligible, versus $8,000 to $11,000 per month for memory care. The arrangement works until cognitive decline progresses to the point where 24-hour secured supervision becomes necessary.

How do I apply for CBAS?

Contact a CBAS center directly. The center handles the initial assessment and the level-of-care determination. The center then submits authorization to the member's Medi-Cal managed-care plan. Some plans require their own case manager to be involved earlier. From first call to first day at the center is usually 30 to 45 days. The CDA and CAADS websites both list centers by county.

Adult day care and CBAS: the Medi-Cal program missed

What adult day care actually is

Adult day care is exactly what it sounds like: a place an older adult goes during the day, for supervision, activities, meals, and (in the medical model) clinical monitoring. The member sleeps at home. The family caregiver gets a workday back. The center provides a structured environment that is harder to replicate at home, with peers, group activities, and trained staff.

California licenses adult day care in two distinct tiers, and the difference between them is the single most important thing for a family to understand.

Two models, very different programs

Social-model adult day care is licensed by CDSS as an Adult Day Program (ADP). It provides supervision, social engagement, hot meals, and structured activities. It does not provide skilled nursing or therapy. Staffing is non-clinical. It is paid privately or through long-term care insurance. Rates in California in 2026 run roughly $20 to $30 per hour, or $80 to $150 per day for a full program day.

Medical-model adult day care, called Community Based Adult Services (CBAS) in California, is a Medi-Cal benefit. It is licensed jointly by CDSS as an Adult Day Health Care center and certified by DHCS as a CBAS provider. It must staff a registered nurse, a social worker, a registered dietitian, and at least one therapist (PT, OT, or speech). It provides medication management, nursing assessment, therapy, behavioral monitoring, and personal care. It is free to eligible Medi-Cal members.

Who qualifies for CBAS

CBAS eligibility runs through Medi-Cal. The member must be enrolled in Medi-Cal (most commonly through a managed-care plan), must be age 18 or older, and must meet the nursing-facility level-of-care criteria. In practice that means one or more of:

A cognitive impairment such as moderate Alzheimer’s or other dementia
Multiple chronic conditions requiring ongoing nursing oversight (poorly controlled diabetes, congestive heart failure, post-stroke deficits)
Functional impairment in two or more ADLs
A serious mental illness with functional consequences
A history that without CBAS would put the member at risk of nursing-facility placement

The CBAS center does the initial level-of-care assessment using the standard CDA criteria. The Medi-Cal managed-care plan authorizes a number of days per week, typically three to five.

What a CBAS day looks like

The member is picked up at home, usually between 7:30 and 9:00 a.m., by a center van or contracted transportation. The driver is trained to assist with ambulation and transfers. The day at the center runs roughly 9:30 a.m. to 2:30 p.m. and includes:

Arrival check, breakfast, and a nursing vital-sign and medication check
Morning activity (cognitive games, light exercise, gardening, music)
Scheduled therapy sessions for members on a PT or OT plan
A hot lunch with dietary modifications for diabetic, renal, low-sodium, or texture-modified diets
Afternoon activity, often something quieter (art, reminiscence groups, intergenerational visits)
Personal care as needed (toileting, repositioning, snack)
Return transportation home, typically arriving 3:30 to 4:00 p.m.

The center documents everything in the member’s record, communicates concerns to the family and the primary care provider, and adjusts the care plan quarterly.

Why CBAS is underused

For a Medi-Cal-eligible senior with moderate functional or cognitive impairment, CBAS is one of the single most consequential benefits in California. It provides daytime medical supervision, structured engagement, meals, transportation, and respite for the family, at no cost. The alternative for the same person is often a memory-care or skilled-nursing placement at $8,000 to $12,000 per month.

And yet CBAS attendance in California is well below the population that would qualify. Three reasons recur. Discharge planners at hospitals and SNFs often do not mention CBAS, defaulting instead to home health or skilled nursing. Primary care physicians are not familiar with the program. And families searching for “adult day care” on Google get directed to private-pay social programs without learning that a free medical alternative exists.

How to access CBAS

Find a CBAS center in the member’s county. The California Association for Adult Day Services (caads.org) and the California Department of Aging both publish directories.
Call the center for an intake. The center handles eligibility, scheduling, and authorization.
The center conducts a level-of-care assessment using the CDA criteria, typically in the member’s home.
The center submits to the member’s Medi-Cal managed-care plan for authorization. Authorization usually comes through in two to four weeks.
Attendance starts. The first week is an adjustment period. Most members settle in within three to four weeks if the center is a reasonable cultural and language fit.

Language and cultural match matter more than people expect. California CBAS centers serve a diverse population, and many centers specialize in Chinese, Korean, Vietnamese, Spanish, Russian, Armenian, or Filipino communities, with food, music, and language reflecting the population they serve. A member who is reluctant to attend often does much better at a center where they hear their first language at lunch.

How CBAS stacks with other Medi-Cal supports

CBAS combines well with IHSS personal care. A typical arrangement: CBAS three days a week (Monday, Wednesday, Friday) at the center, IHSS hours on the other days and evenings, family caregiving on weekends. The total support package can rival what a nursing facility would provide, at zero cost to the member.

CBAS also works alongside Medicare home health during a covered episode. The member can attend CBAS on days when home-health visits are not scheduled. The two programs do not bill against each other.

Social-model adult day care: when it is the right answer

For families who do not qualify for Medi-Cal, or who want shorter-day engagement without the medical model, social adult day care can work well. Look for an Adult Day Program licensed by CDSS, with a reasonable staff-to-participant ratio (1:8 is good), a planned activity calendar, and a clean physical space. Tour at mid-morning to see how the day actually flows.

Some social-model programs accept long-term care insurance reimbursement, which is worth asking about if the family has a policy.

Common misconceptions to clear up

“Adult day care is for older adults who are still active.” Social-model programs lean that way. CBAS is specifically designed for members with significant functional or cognitive impairment, including those who would otherwise need nursing-facility care.

“Medicare will cover it.” Original Medicare does not. Some Medicare Advantage plans include a limited benefit, but it is small. The reliable answer is CBAS through Medi-Cal or private pay.

“My parent won’t want to go.” Common at first, less common after the first three weeks. A good center matches language, culture, and food. Most members who initially resist end up looking forward to the days they attend.
