Home health care is one of those Medicare benefits that sounds straightforward until someone actually needs it. A doctor orders nursing or therapy at home, so Medicare pays for someone to come to the house. Simple enough.
The reality has more layers.
Original Medicare and Medicare Advantage both cover qualifying Medicare home health services, but they can deliver that coverage differently. Original Medicare generally gives beneficiaries broader choice among Medicare-certified home health agencies and charges $0 for covered home health services. Medicare Advantage must cover at least the Medicare home health benefit, but a private plan may add network requirements, prior authorization, referrals, and its own cost-sharing rules.
Neither option turns Medicare into round-the-clock home care or long-term caregiving coverage.
For me, that is the most important place to begin: the basic Medicare eligibility rules matter under either route, while the biggest differences often involve access, approvals, provider choice, and costs.
First, Understand What Medicare Means by Home Health Care
Medicare home health is a medical benefit for qualifying care delivered where a beneficiary lives. It is not a general benefit for anyone who needs assistance at home.
Under current Medicare home health coverage, covered services can include:
- Part-time or intermittent skilled nursing
- Physical therapy
- Occupational therapy under applicable requirements
- Speech-language pathology
- Medical social services
- Certain medical supplies
- Part-time or intermittent home health aide services when qualifying skilled services are also being received
- Durable medical equipment under separate cost-sharing rules
To qualify, the beneficiary generally must be homebound and need qualifying part-time or intermittent skilled nursing care or therapy.
Being homebound does not mean someone is literally forbidden to leave the house.
A person can leave for medical care and can have short, infrequent nonmedical absences. The key is generally that leaving home is difficult because of illness or injury, may require assistance or equipment, and takes considerable effort.
There is also no rule saying someone first has to spend three days in a hospital before receiving Medicare home health care. That requirement belongs to a different Medicare benefit involving certain skilled nursing facility stays.
Home health coverage begins with the need for skilled care at home, not simply with the need for help at home.
That distinction determines much of what Medicare will and will not pay for.
The Eligibility Standard Is Largely the Same Under Both Options
A Medicare Advantage plan cannot simply invent a narrower version of the basic Medicare home health benefit.
Medicare Advantage plans are required to provide Part A and Part B benefits, including qualifying home health services. The plan can administer those benefits through its own network and utilization-management structure, but the basic Medicare coverage entitlement remains important.
Current CMS guidance for home health eligibility confirms that qualifying care requires a plan of care, appropriate skilled need, homebound status, and a qualifying face-to-face encounter.
For 2026, that face-to-face encounter generally must occur no more than 90 days before the start of home health care or within 30 days afterward and must relate to the primary reason home health services are needed.
If continuing home care remains necessary, eligibility and the plan of care are generally recertified and reviewed at least every 60 days.
So choosing Medicare Advantage rather than Original Medicare does not turn someone who needs only housekeeping into a Medicare home health patient. And choosing Original Medicare does not waive the homebound or skilled-care requirements.
The coverage foundation is similar.
The path through that coverage can be quite different.
5 Differences That Can Matter Once Care Starts
1. Original Medicare generally offers more agency flexibility.
Under Original Medicare, qualifying home health care must come from a Medicare-certified home health agency.
You can generally choose among Medicare-certified agencies that serve your area and are willing and able to accept you as a patient.
That can matter after a hospital discharge.
Suppose Evelyn needs wound care and physical therapy at home following surgery. Three Medicare-certified agencies serve her ZIP code. One can begin tomorrow, another specializes in orthopedic rehabilitation, and a third cannot accept new patients for several days.
Under Original Medicare, Evelyn can generally evaluate the available Medicare-certified agencies without first narrowing the list to one private insurer's contracted network.
Medicare Advantage is different.
A plan may require home health care to come from agencies in its network. The Medicare Rights Center's current explanation of Medicare Advantage home health notes that plans can impose network, referral, prior-authorization, and cost-sharing requirements that Original Medicare does not use in the same way.
If the network contains several strong agencies with capacity, that may work perfectly well.
If the available in-network agencies have staffing shortages or cannot accept a new case, access becomes a more important part of the comparison.
2. Prior authorization can be a bigger issue with Medicare Advantage.
A physician ordering home health care does not necessarily mean a Medicare Advantage plan will immediately authorize everything requested.
The plan may require prior approval for the service or for continued treatment.
This does not mean Medicare Advantage plans can disregard Medicare coverage standards. CMS has strengthened rules requiring Medicare Advantage coverage decisions to align with Traditional Medicare coverage requirements and limiting how plans use internal criteria.
Still, prior authorization remains considerably more common across Medicare Advantage than across Original Medicare.
KFF's latest analysis of Medicare Advantage prior authorization found nearly 53 million prior-authorization determinations in Medicare Advantage in 2024, compared with just over 625,000 prior-authorization reviews in Traditional Medicare across the limited categories then subject to such review.
That statistic covers much more than home health care, so it should not be interpreted as a home-health denial rate.
It does show why utilization management deserves attention when comparing the two Medicare approaches.
If someone is leaving a hospital and needs home care to begin quickly, I would ask the Medicare Advantage plan and discharge team whether authorization has been obtained before the discharge date rather than assuming the referral has completed the coverage process.
3. Original Medicare has unusually favorable cost-sharing for the covered home health service itself.
For qualifying Original Medicare home health services, the beneficiary generally pays $0.
That applies to the covered skilled nursing, therapy, social work, and qualifying home health aide services included in the home health benefit.
Durable medical equipment follows different rules. After the applicable Part B deductible, Original Medicare generally requires 20% coinsurance of the Medicare-approved amount for covered equipment such as certain walkers, wheelchairs, or hospital beds.
Medicare Advantage cost-sharing can vary by plan.
A plan may structure its Medicare-covered services differently within federal requirements, which is why I would check the current Evidence of Coverage rather than assume that seeing a nurse or therapist at home will have the same $0 member cost as Original Medicare.
Also look at the bigger annual picture.
Medicare Advantage plans have an annual out-of-pocket limit for Part A and Part B services. Original Medicare itself does not have an annual out-of-pocket ceiling, although someone with Medigap or other secondary coverage may have additional protection against Medicare cost-sharing.
That means home health cost alone should not determine which Medicare route looks financially stronger.
The home health visit may cost $0 under Original Medicare, but the better Medicare comparison still includes the rest of the year’s hospital, physician, therapy, equipment, and plan costs.
4. Medicare Advantage may offer extra in-home benefits that are not the Medicare home health benefit.
This is an area where marketing can create confusion.
Some Medicare Advantage plans offer supplemental services designed to help members at home. Depending on the plan and eligibility requirements, those benefits might include limited in-home support, caregiver assistance, meal benefits, transportation, or other services.
Those extras are separate from the basic Medicare home health entitlement.
That distinction matters because a plan could offer, for example, a limited number of hours of supplemental in-home assistance without changing Medicare's rule that routine custodial care by itself is not covered under the standard home health benefit.
Likewise, the supplemental benefit may have its own:
- Eligibility rules
- Provider network
- Service limits
- Authorization requirements
- Number of allowable hours
- Annual benefit cap
I would never translate “in-home support included” into “this plan pays for ongoing caregiving.”
Ask what the benefit provides in actual hours and services.
5. Appeals and notices work differently enough to prepare for them.
Home health care can be reduced or stopped because the agency or payer determines that coverage requirements are no longer met.
Under Original Medicare, beneficiaries have formal notice and appeal protections. A home health agency may issue an Advance Beneficiary Notice when it believes Medicare will not pay for certain services, and beneficiaries receive notice when covered home health services are ending.
Medicare Advantage also has coverage-determination and appeal rights, but the plan itself becomes part of the decision process.
That difference matters when the disagreement involves prior authorization, continued visits, or whether the plan's network can actually furnish the care.
If a Medicare Advantage plan denies a service, I would read the denial notice rather than accepting a verbal “insurance won't cover it.” The written notice should explain the reason and the applicable appeal process.
And if care is being terminated, act quickly. Fast-appeal deadlines can be short.
Medicare Does Not Require You to Keep “Improving”
There is a persistent Medicare myth that home health therapy or skilled nursing ends once the patient stops getting noticeably better.
That is not the Medicare standard.
A beneficiary can qualify for skilled care needed to maintain function or prevent or slow deterioration, provided the other Medicare requirements continue to be met.
The Center for Medicare Advocacy's current guidance on the Medicare improvement standard emphasizes that improvement potential is not required when skilled care remains necessary for safe and effective maintenance.
Consider Arthur, who has a progressive neurological condition.
Physical therapy may not be expected to return him to his mobility level from five years earlier. But a skilled therapist might still be necessary to maintain transfers safely, prevent avoidable deterioration, or train a caregiver in techniques specific to Arthur's changing condition.
The fact that Arthur has a chronic condition does not by itself disqualify him from Medicare home health.
This principle applies whether his Part A and Part B benefits are delivered through Original Medicare or Medicare Advantage.
Medicare home health is not limited to recovery. Skilled care can also be about preserving function or slowing decline when the coverage requirements are met.
What Neither Original Medicare Nor Medicare Advantage Normally Covers
The biggest home-care gap survives either Medicare choice.
Medicare does not generally pay for:
- 24-hour care at home
- Meal delivery under the Original Medicare home health benefit
- Routine housekeeping unrelated to the medical care plan
- Shopping and similar homemaker services
- Personal care when personal care is the only help needed
- Long-term custodial caregiving simply because someone cannot live independently
A home health aide can be covered when the beneficiary qualifies for Medicare home health and is also receiving qualifying skilled nursing or therapy services.
That can include hands-on assistance such as bathing or grooming.
But if the skilled-care requirement ends and the person's continuing need is simply daily help bathing, dressing, toileting, eating, or supervising dementia-related needs, the ordinary Medicare home health benefit generally does not become an indefinite personal-care benefit.
At that point, Medicaid, long-term care insurance, VA programs, personal resources, or other community-based assistance may become more relevant.
What I Would Compare Before Choosing One Route for Home Health Needs
Someone who already knows that home-based medical care is likely to matter should look beyond the usual Medicare questions about premiums and prescription drugs.
Start with agency availability.
For Original Medicare, identify the Medicare-certified agencies serving the area and whether they are accepting patients.
For Medicare Advantage, search the plan's contracted home health network and then ask whether those agencies are actually taking new referrals. A directory listing alone does not guarantee staffing capacity.
Then check authorization.
Does the plan require prior approval for initial visits? For additional therapy? How quickly are decisions made after hospital discharge?
Look at cost-sharing.
Does the Medicare Advantage plan charge anything for covered home health? How is durable medical equipment handled? What is the plan's annual out-of-pocket maximum?
And consider the rest of the coverage.
A broad home health network is useful, but so are access to cardiologists, hospitals, rehabilitation facilities, prescriptions, and other services likely to surround a serious illness.
Home health rarely exists in isolation.
The Quote Check!
Before deciding which Medicare structure better supports home health needs, I would make these five checks:
- Check the eligibility, not just the diagnosis: Homebound status and a qualifying need for skilled nursing or therapy are central under both Original Medicare and Medicare Advantage.
- Check the actual agencies: Compare Medicare-certified agencies available through Original Medicare with the specific home health network of any Medicare Advantage plan.
- Check prior authorization: Ask whether the Medicare Advantage plan requires approval before care starts or before additional visits continue.
- Check the full cost structure: Original Medicare charges $0 for qualifying covered home health services, but equipment and other Medicare care can have cost-sharing. Medicare Advantage costs vary by plan.
- Check what happens after skilled care ends: Neither option should be mistaken for unlimited custodial caregiving or round-the-clock personal assistance at home.
The Benefit May Be the Same, but the Route to It Is Not
Original Medicare and Medicare Advantage start from the same basic promise: qualifying Medicare beneficiaries can receive covered skilled home health care when the Medicare requirements are met.
The experience of using that benefit can still differ substantially.
Original Medicare generally provides broader flexibility among Medicare-certified home health agencies and charges no cost-sharing for the covered home health service itself. Medicare Advantage may provide the same core benefit through a narrower network, additional authorization rules, different cost-sharing, and potentially useful supplemental in-home benefits.
I would compare those practical details before a hospital discharge or health crisis makes the decision urgent.
The important question is not simply whether a plan says “home health covered.” It is whether the right agency can get through the coverage rules and into the home when skilled care is actually needed.
