What is the Medicare home-health 100-day myth?

There is no 100-day cap on Medicare home health. The 100-day rule belongs to Medicare's skilled nursing facility benefit (Part A), which is a different service entirely. Home health is paid in 60-day episodes, re-certified as long as the patient remains homebound and has a continuing skilled need. The misunderstanding causes families to plan around a deadline that does not exist.

What does 'homebound' actually mean?

It means leaving home requires considerable and taxing effort. A homebound patient may still leave for medical appointments, occasional family events, or religious services without losing eligibility. They do not have to be bedbound. The CMS criteria look at whether the person normally needs supportive assistance or has a condition that makes leaving home difficult.

Who pays the home-health agency?

Medicare pays the agency directly under the Patient-Driven Groupings Model (PDGM). The patient has no co-pay for covered services. For Medi-Cal members, the agency bills Medi-Cal as a wraparound or as the primary payer if the member is not Medicare-enrolled.

What happens when Medicare home health stops?

Medicare stops when the skilled need ends, the wound heals, the post-stroke therapy plateaus, the IV course finishes, even if the patient still needs custodial care. Families typically transition at that point to IHSS (Medi-Cal), private-pay non-medical home care, or a combination, depending on need and eligibility.

Can the same agency provide both home health and home care?

Sometimes. Many California agencies hold both a Home Health Agency (HHA) license from CDPH and a Home Care Organization (HCO) registration from CDSS, which lets them provide medical and non-medical services. The billing and the staff are different even when the agency is one.

Does Medi-Cal cover home health?

Yes. Medi-Cal covers home health services through Medi-Cal Managed Care plans and Fee-for-Service. The eligibility rules are similar to Medicare's (skilled need, physician order) but Medi-Cal does not require homebound status, which is a meaningful difference for dual-eligible patients who can move around.

Home health care: Medicare coverage and eligibility

What Medicare home health actually is

Medicare home health is a medical service. A nurse, a physical therapist, an occupational therapist, or a speech therapist comes to the home for short visits, a few times a week, for a defined clinical reason: a wound that needs dressing changes, post-surgical recovery, IV antibiotic management, post-stroke rehabilitation, swallowing therapy, oxygen titration. The visits are brief, the care is targeted, and the episode ends when the skilled need ends.

Two conditions must hold for Medicare to pay. The patient must be homebound, meaning leaving home takes considerable and taxing effort. And the patient must need intermittent skilled care, which the clinician documents and a physician orders during a face-to-face encounter.

A home health aide may also visit to help with bathing or dressing during a covered episode, but that aide is part of the bundle, not a standalone benefit. When the skilled need ends, the aide visits stop too.

What Medicare covers, and what it does not

Medicare covers, in full and without a co-pay during a qualifying episode: skilled nursing visits, physical therapy, occupational therapy, speech-language pathology, medical social services, and part-time home health aide services as part of the plan of care. Durable medical equipment used during home health is billed separately under Part B with the standard 80/20 split.

Medicare does not cover ongoing personal care without a skilled need, meal delivery, homemaker services, or 24-hour-a-day care. It does not pay a family member to be the caregiver. It does not cover live-in arrangements. It does not cover services from an agency that is not Medicare-certified.

What Medi-Cal adds in California

Medi-Cal covers home health independently. For a dual-eligible member, Medicare pays first and Medi-Cal picks up cost-sharing and additional service hours that Medicare does not authorize. For a Medi-Cal-only member, Medi-Cal pays primarily, through a managed-care plan in most counties, and crucially does not require homebound status. That last point matters for many older adults who are mobile enough to leave home but still need skilled care episodes at home.

After Medicare home health ends, Medi-Cal members can transition to IHSS for personal care, to CBAS for adult day health, and to Community Supports under CalAIM for services like recuperative care or asthma remediation that bridge between hospital and home.

How home health and non-medical home care differ

Two services, two different licenses, two different payers, two completely different scopes. Home health is short, skilled, doctor-ordered, Medicare-paid, delivered by a CDPH-licensed Home Health Agency. Non-medical home care is ongoing, custodial, family-or-caregiver-arranged, paid by Medi-Cal IHSS or LTC insurance or private pay, delivered by a CDSS-registered Home Care Organization.

The most common confusion: a family hears "home health" from the hospital, assumes Medicare will pay for someone to come every day to help mom shower, and is shocked three weeks later when Medicare stops and the help walks out the door. The mismatch is structural. Knowing it in advance changes how you plan.

How to access Medicare home health

The order of operations:

A physician identifies a skilled need (post-discharge, post-procedure, ongoing condition with a new complication).
A face-to-face encounter is documented within 90 days before or 30 days after the start of care.
A Medicare-certified home health agency is chosen. CDPH publishes the list; hospital discharge planners typically have one or two they default to.
The agency completes the OASIS assessment, builds a plan of care, and the physician signs.
Care begins. The episode lasts 60 days. Re-certification is required to continue.

For Medi-Cal-only patients in California, the entry point is the Medi-Cal managed-care plan’s care manager, who arranges referral to a plan-contracted home health agency.

What it costs in California

For a Medicare beneficiary, the patient pays $0 during a qualifying episode. Durable medical equipment associated with home health is billed under Part B with the standard 20% co-insurance unless covered by Medi-Cal, Medigap, or Medicare Advantage cost-sharing rules.

Without Medicare or Medi-Cal coverage, private-pay home-health rates in California in 2026 average $130 to $190 per nursing visit and $100 to $150 per therapy visit, varying by region and agency.

Common misconceptions to clear up

“Medicare home health is a 100-day benefit.” No. The 100-day rule is the SNF benefit, a different Medicare service. Home health has no fixed length and can continue across many 60-day episodes as long as eligibility holds.

“Once Medicare home health starts, my parent gets a daily caregiver.” No. The visits are short, targeted, and infrequent. Aide visits are part of the skilled plan and stop when the skilled need ends.

“My parent has to be bedbound to qualify as homebound.” No. Homebound means leaving home requires considerable and taxing effort. A patient who can leave occasionally for appointments or religious services can still qualify.

“Medi-Cal doesn’t cover home health.” It does. The benefit is broader than Medicare in one important way: Medi-Cal does not require homebound status.
