Medicare Home Health Coverage Rules: What's Covered, Limits, and How to Qualify

Medicare covers home health care at 100% — no copays, no deductibles, no coinsurance. But the eligibility rules are strict and confusing, and families routinely miss benefits they are entitled to or lose coverage they thought was guaranteed.

Here is how Medicare home health actually works: who qualifies, what is covered, what is not, and the critical timelines families need to understand.

The Homebound Requirement

To qualify for Medicare home health, your parent must be "homebound." This does not mean they can never leave the house. It means leaving home requires a considerable and taxing effort due to their medical condition.

Your parent qualifies as homebound if:

• They need a supportive device (walker, wheelchair, crutches) to leave
• They need the help of another person to leave safely
• Leaving home is medically inadvisable due to their condition
• They are unable to leave without considerable effort due to physical limitations

Your parent can still leave home for medical appointments, religious services, adult day programs, and occasional short non-medical outings (a family dinner, a haircut) without losing homebound status. The key is that these outings are infrequent and short.

Under the Jimmo v. Sebelius settlement, Medicare coverage cannot be denied simply because the patient's condition is not expected to improve. Skilled care to maintain function or prevent deterioration qualifies. If your parent's coverage is denied on "improvement" grounds, this is a basis for appeal.

What Medicare Home Health Covers

Skilled nursing visits. Registered nurses provide wound care, medication management, injection administration, catheter care, vital sign monitoring, and caregiver education. Covered at 100%.

Physical therapy. Mobility training, balance exercises, transfer safety, strength building, and gait training. Covered at 100%.

Occupational therapy. Activities of daily living retraining (dressing, bathing, cooking), home modification recommendations, and adaptive equipment training. Covered at 100%.

Speech-language pathology. Swallowing evaluation and therapy, cognitive rehabilitation, and communication training after stroke. Covered at 100%.

Medical social services. Counseling, community resource referrals, and care coordination. Covered at 100%.

Home health aide services. Help with bathing, dressing, and personal care. Covered only when part of a care plan that includes one of the skilled services above.

How Many Therapy Visits Does Medicare Cover?

There is no fixed visit limit for Medicare home health therapy. Coverage is based on medical necessity, not a predetermined number. As long as the patient remains homebound and continues to need intermittent skilled care, visits continue.

Each 60-day certification period requires a physician to recertify that the patient still meets eligibility criteria. The agency submits a CMS-485 Plan of Care that specifies the type, frequency, and duration of each service. Common patterns:

• Physical therapy: 2 to 3 visits per week during active recovery, tapering to 1 per week during maintenance
• Skilled nursing: 1 to 3 visits per week depending on wound complexity and medication changes
• Occupational therapy: 1 to 2 visits per week

There is no lifetime maximum for home health visits. Your parent can receive home health across multiple certification periods as long as they continue to qualify.

The 100-Day Rule: Skilled Nursing Facilities, Not Home Health

Families frequently confuse the 100-day rule with home health. They are entirely separate benefits:

Medicare Part A skilled nursing facility (SNF) coverage: After a qualifying 3-day hospital stay, Medicare covers up to 100 days in a skilled nursing facility. Days 1 through 20 are fully covered. Days 21 through 100 require a daily copay (currently over $200 per day). After day 100, coverage ends completely.

Medicare home health: No day limit. No copays. No deductibles. Not tied to a prior hospital stay. These are Part A and Part B benefits that operate independently of SNF coverage.

The 100-day clock applies only to SNF stays. A parent who exhausts their SNF days can still qualify for unlimited home health visits at no cost.

How to Get Medicare to Pay for a Hospital Bed

Durable Medical Equipment (DME) like hospital beds is covered under Medicare Part B. The process:

1. Get a physician's prescription. The prescribing doctor must document medical necessity using specific diagnosis codes. For a hospital bed, the patient typically needs to be unable to get in or out of a standard bed safely, require specific positioning for a medical condition, or need elevation that a standard bed cannot provide.

2. Use a Medicare-approved DME supplier. The supplier must be enrolled in Medicare and operate in your parent's competitive bidding area. Check Medicare's Supplier Directory.

3. Understand the cost split. After meeting the Part B deductible, Medicare pays 80%. Your parent pays 20% of the Medicare-approved amount. For a semi-electric hospital bed, the purchase price runs $1,000 to $2,500, making the patient's share $200 to $500.

4. Rental vs purchase. Medicare typically rents DME for 13 months, then transfers ownership. During the rental period, the 20% copay applies to each monthly rental payment. If your parent has a Medicare Supplement (Medigap) plan, it may cover the 20% copay.

Other DME covered under Part B: wheelchairs, walkers, shower chairs (when prescribed), oxygen equipment, CPAP machines, and blood glucose monitors.

What Medicare Home Health Does Not Cover

• 24-hour continuous care
• Home-delivered meals (Meals on Wheels)
• Homemaker services (cleaning, laundry, grocery shopping) when no skilled service is also provided
• Personal care aide services when no skilled service is also provided
• Custodial care (long-term help with daily activities without a skilled component)

For these services, families need Medicaid HCBS waivers, Veterans benefits, or private payment. The Rehab and Recovery at Home Toolkit includes a cross-jurisdictional funding guide that maps every available program — Medicare, Medicaid, VA, and state-specific — to your parent's specific care needs.
