Hospital at Home in California: CMS Acute Hospital Care at Home

Questions people ask

Is Hospital at Home the same as Medicare home health?

No. CMS describes Acute Hospital Care at Home as inpatient hospital care for someone who needs a hospital admission, with daily physician rounding and a medical team watching the stay. Medicare home health is a separate benefit: part-time or intermittent skilled nursing and therapy from a Medicare-certified agency when homebound and skilled-need rules are met. A home-health referral after discharge is a different file. Read Medicare.gov on home health services, and ask the case manager which one they mean.

Does Hospital at Home replace IHSS or family caregiving?

No. IHSS is county-authorized personal care for a person living in a home they choose, after Medi-Cal and an assessment. Family caregiving is unpaid help, unless someone later enrolls as an IHSS provider and the county authorizes tasks. During Acute Hospital Care at Home the person is still a hospital inpatient. IHSS does not run that admission. Ask the county about IHSS for the home after the hospital episode ends.

How long does the CMS Acute Hospital Care at Home initiative last?

CMS says the initiative was extended by the Consolidated Appropriations Act, 2026. On the CMS QualityNet page, hospitals with active waivers must discharge inpatients or return them to the hospital on September 30, 2030, unless Congress extends the initiative. CMS will not accept new waiver requests after September 1, 2030. Confirm those dates on the CMS page. A single admission lasts as long as the hospital says this person still needs inpatient care. This page does not quote a length of stay.

Does Medi-Cal pay for Hospital at Home?

Do not assume it does. CMS tells hospitals that want Medicaid reimbursement to contact the state Medicaid agency, because other state rules may apply. In California that agency is the Department of Health Care Services. Ask the hospital billing office and DHCS, or the Medi-Cal plan, whether this stay is covered. A Medicare fee-for-service hospital claim and a Medi-Cal claim are different conversations.

Is the person discharged from the hospital once they are in the house?

Not while the hospital is still calling the stay an Acute Hospital Care at Home admission. CMS describes it as inpatient care delivered in the home. Going home with help, after the hospital writes a discharge, is the next chapter. Ask the case manager to say, in one sentence, whether this night is still an inpatient night.

What if the home cannot support Hospital at Home?

Say so before anyone agrees. CMS has described screening for working utilities, physical barriers, and safety concerns before care at home begins, and it has said receiving this care at home is the patient's choice. If heat, water, electricity, a working phone, or a safe room is missing, tell the case manager. Ask what happens if the person needs to return to the hospital building. A longer inpatient stay or a skilled nursing stay can be the honest next setting.
