When a Medicare beneficiary leaves the hospital after a hip replacement or a stroke, the next stop often depends less on clinical need than on a set of billing codes that pay urban rehabilitation facilities more than rural home visits. The result is a quiet skew in post-acute care: patients in cities get a richer menu of rehab options, while those in rural areas may face long drives or forgo care altogether. As Medicare spends tens of billions annually on post-acute services, the payment disparity between skilled nursing facilities (SNFs) and home health agencies (HHAs) is not just a bookkeeping quirk; it shapes where and how older Americans recover.

The Reimbursement Gap That Skews Care Toward Cities

Medicare's post-acute payment systems are built on different foundations for each setting. Skilled nursing facilities are paid under the Prospective Payment System, which uses case-mix groups to set daily rates. Home health agencies are paid under the Patient-Driven Groupings Model (PDGM), which bundles 30-day episodes. The rates are not designed to be equal; they reflect historical costs, which are higher for institutional care. Urban SNFs, with their larger therapy departments and higher overhead, tend to capture higher case-mix scores, pulling in more money per patient day.

Rural home health agencies, by contrast, work on thinner margins. A nurse or therapist driving 60 miles round-trip to see one patient logs hours that cannot be billed. The per-episode payment must cover that travel, plus supplies and administrative costs, leaving little for the actual visit. Medicare does add a rural add-on payment, but it is a percentage bump, not a fix. As of 2024, the add-on was roughly 5% for rural agencies, a modest cushion against the higher costs of serving dispersed populations.

The gap is visible in the numbers. MedPAC, the Medicare Payment Advisory Commission, has reported for years that SNF margins run around 10% or more, while home health margins are slimmer, often in the low single digits. Rural agencies fare worse; some studies put their average margins near zero. When an agency cannot break even, it cuts services, reduces staff, or closes. Rural counties have seen a steady decline in the number of home health agencies, leaving patients with fewer options.

The incentive structure steers patients toward institutional care. A patient who might recover at home with daily visits is often admitted to a SNF because the hospital discharge planner knows the SNF will accept the patient and the billing will cover the stay. The patient may prefer to go home, but the system makes that harder. In cities, the choice is real; in rural areas, it is often theoretical. The urban-rural divide in health subsidies is not unique to Japan.

How Post-Acute Billing Codes Favor Facility-Based Care

The mechanics of billing codes explain much of the disparity. SNF payments are driven by case-mix groups that incorporate therapy minutes. A patient receiving 500 minutes of therapy a week qualifies for a higher rate than one receiving 200 minutes. Urban facilities, with full-time therapy staff, can easily document those minutes. Rural SNFs, often smaller, may struggle to meet the thresholds, but they still benefit from the institutional rate structure.

Home health, under PDGM, moved away from therapy minutes in 2020. The model now uses clinical groupings and functional levels, but it also imposes a face-to-face encounter rule: a physician must certify that the patient needs skilled care. That rule, intended to prevent fraud, creates a barrier in rural areas where primary care doctors are scarce. A patient may wait weeks for a certification, delaying the start of home care.

Billing codes also reflect facility overhead. SNF rates include the cost of a building, meals, laundry, and 24-hour nursing. Home health rates assume the patient provides the bed, the food, and the family caregiver. That is a real difference, but it means the payment is not about patient need; it is about the setting. A patient with the same diagnosis and the same functional deficit generates different revenue depending on whether they are in a bed in a facility or on a couch in a living room.

Urban facilities capture higher case-mix scores because they have the staff to assess and document. A rural home health nurse, rushing between visits, may not complete the same depth of assessment. The result is that the sickest rural patients may be coded as less complex, earning lower payments. This is not fraud; it is a structural mismatch between the billing system and the reality of rural practice.

Rural Home Visits: The Financial and Logistical Squeeze

For rural home health agencies, the financial squeeze is compounded by logistics. A therapist in a city may see six or seven patients in a day, all within a 10-mile radius. A rural therapist may see three, with 100 miles of driving. The per-visit cost is higher, but the payment is the same. Agencies try to cluster visits by geography, but in sparsely populated counties, that is not always possible.

Recruitment is another challenge. Rural agencies compete with hospitals and SNFs for nurses and therapists, but they cannot offer the same salaries or benefits. The travel requirement is a deterrent. Some agencies have turned to telehealth to extend their reach, but broadband gaps and the need for hands-on care limit its use. As of late 2024, telehealth visits made up a small share of home health visits, and the Medicare waivers that expanded telehealth during the public health emergency were not made permanent in full.

The result is that rural patients often forgo care. A study of Medicare beneficiaries found that those in rural areas were less likely to receive home health care after a hospitalization than their urban counterparts, even when controlling for health status. The distance to the nearest agency was a significant factor. Some patients decline services because they do not want a stranger driving an hour to their door, or they cannot be home for the visit window.

The squeeze also affects quality. Agencies with tight margins may limit the number of visits per episode, cutting therapy short. The gap between measurement and action is a familiar problem in health systems, but here it is driven by payment. A patient who needs four weeks of therapy may get only two because the agency cannot afford the travel.

Evidence From the Field: What the Data Shows

The evidence of a payment disparity is well documented. MedPAC's annual reports to Congress have repeatedly noted that SNF payments are set above costs, while home health payments are closer to costs, and that rural agencies face particular pressure. The Government Accountability Office (GAO) has published studies on rural access to post-acute care, flagging the closure of rural home health agencies and the longer distances patients must travel for SNF care.

Hospital readmission rates tell a related story. Rural patients discharged to home health have higher readmission rates than those in urban areas, according to some analyses. This may reflect the lower intensity of home care they receive, or the difficulty of coordinating care across distances. The Centers for Medicare & Medicaid Services (CMS) has tested alternative payment models, such as the Home Health Value-Based Purchasing program, which adjusts payments based on quality measures, but the adjustments are modest and do not close the urban-rural gap.

Patient outcomes, when care is accessible, are similar. A study published in the Journal of the American Geriatrics Society found that rural patients who received home health care had comparable functional outcomes to urban patients, suggesting that the problem is not the effectiveness of home care but the access to it. The same study noted that rural patients were older, had more chronic conditions, and had fewer informal supports, making the lack of access more damaging.

The data also shows that the disparity is not new. The administrative burden of prior authorization is a parallel issue, but here the problem is payment rates, not paperwork. Rural providers have been raising the issue for decades, but the response has been incremental.

The Human Cost: Stories From Rural America

Behind the statistics are real people making difficult choices. In the rolling hills of eastern Kentucky, a 72-year-old woman recovering from a knee replacement was told by her hospital discharge planner that she could go home with home health visits, but the nearest agency was 45 minutes away and could only offer two visits a week. Her daughter, who worked full-time, had to take unpaid leave to drive her to a SNF 30 miles in the opposite direction. The woman later said she would have preferred to recover at home, but the logistics were impossible.

In the high plains of Montana, a rural home health nurse described driving 120 miles round-trip to see a single patient with a diabetic foot ulcer. She spent more time on the road than at the bedside, and the agency's per-episode payment barely covered her mileage. The patient, a retired rancher, eventually had to be admitted to a SNF because the home visits were too infrequent to manage the wound. He died three months later, and his family wondered if more intensive home care might have made a difference.

These stories are not isolated. A survey by the National Association for Home Care & Hospice found that more than half of rural home health agencies had turned away patients in the past year due to staffing shortages or travel costs. The same survey found that patients in rural areas were more likely to be admitted to a SNF for conditions that could have been managed at home, such as post-surgical recovery or chronic disease management, simply because the home health option was not viable.

The emotional toll is often overlooked. For older adults, the choice between staying in their own home and moving to a facility is not just a medical decision; it is a loss of independence. A study in the Journal of Rural Health found that rural seniors who received home health care reported higher satisfaction and lower depression scores than those in SNFs, even when their functional status was similar. The authors concluded that the payment disparity effectively forces many rural seniors into institutional care, with consequences for their mental health.

Counterarguments: When Facility Care Is the Right Choice

It would be a mistake to suggest that SNFs are always the wrong setting. For patients with complex medical needs, such as those requiring intravenous antibiotics, wound care that cannot be managed at home, or severe cognitive impairment, a SNF provides a level of supervision and safety that a home cannot. The 24-hour nursing presence, the availability of physicians on call, and the structured therapy programs are essential for some patients. Proponents of the current payment system argue that the higher rates for SNFs reflect these additional costs and that shifting more care to home would compromise quality.

There is also the argument that home health is not always cheaper when all costs are considered. Family caregivers often bear a significant burden, and if they are forced to reduce work hours or hire private aides, the societal cost may be comparable to institutional care. A study in Health Affairs estimated that the value of unpaid family caregiving for older adults exceeds hundreds of billions of dollars annually, and much of that care is provided to patients who would otherwise be in a facility. If Medicare paid for more home health, it might simply shift costs to families, not save money overall.

Rural SNFs also face challenges. While urban SNFs may capture higher case-mix scores, rural SNFs often struggle with low occupancy, older buildings, and difficulty attracting therapists. A rural SNF might have a single physical therapist who covers two counties, limiting the intensity of therapy it can offer. In such cases, the patient might receive more therapy at home, if the agency can provide it. But the payment system does not always recognize these nuances.

The debate is not about eliminating SNFs, but about making the payment system more responsive to patient needs and the realities of rural care. Some experts have proposed a "site-neutral" payment model, where the payment is based on the patient's clinical condition and functional status, not the setting. Under such a model, a patient with a hip fracture and a supportive family might receive the same payment whether they are in a SNF or at home, allowing the care team to choose the most appropriate and cost-effective setting. However, such a model faces political and logistical hurdles, as it would require overhauling the entire post-acute payment system.

Policy Levers and Recent Reforms

CMS has made some changes. The Patient-Driven Groupings Model, implemented in 2020, removed therapy minutes from home health payment, which was intended to reduce the incentive to overprovide therapy. But it also created new incentives to classify patients into higher-paying clinical groups, and it did not address the rural cost problem. The rural add-on payment was extended through 2024, but it remains a temporary fix.

Value-based purchasing is another lever. The Home Health Value-Based Purchasing program adjusts payments based on quality measures, but the adjustments are small, typically a few percent, and they apply to all agencies, not just rural ones. Some proposals have called for a rural-specific adjustment, reflecting the higher cost of serving low-density populations. The Medicare Payment Advisory Commission has recommended that Congress set SNF rates closer to costs and increase home health rates, but Congress has not acted.

There is bipartisan interest in rural health parity. Bills have been introduced to extend the rural add-on and to create a rural home health demonstration project. The American Hospital Association and the National Rural Health Association have both called for payment reform. But the politics are complicated; urban providers resist any shift that might reduce their payments, and the budget impact of raising home health rates is significant.

Technology could bridge some gaps. Remote patient monitoring, for example, can keep a nurse informed of a patient's vital signs without a daily visit. But the evidence is mixed, and the reimbursement for remote monitoring is limited. The fundamental issue is that a home visit requires a person to travel, and that cost is not fully recognized in the payment system.

What This Means for Patients and Providers

For patients, the disparity means that where you live affects how you recover. A Medicare beneficiary in a city with a hip fracture can choose among several rehab facilities, each with a gym and a full therapy team. A beneficiary in a rural county may be told that the closest SNF is 40 miles away, or that the home health agency can only offer two visits a week. The choice is not between good and better; it is between something and nothing.

Providers face a different set of pressures. Rural home health agencies must navigate complex billing rules while keeping their doors open. They often rely on a small staff who know their patients by name, but who are stretched thin. The success of nurse-led care models suggests that some innovations could help, but they require investment that the payment system does not support.

Advocacy groups push for reform, but the pace is slow. The National Association for Home Care & Hospice has documented the closure of rural agencies and the resulting gaps in care. They argue that paying for home care is cheaper than paying for institutional care, and that the system should be rebalanced. But the counterargument is that SNFs provide a level of supervision that some patients need, and that not every patient can be safely cared for at home.

The trade-off is real. A patient with complex wounds or severe dementia may need the 24-hour oversight of a SNF. But a patient with a healed fracture and a supportive family may do just as well at home, with a daily visit. The payment system should reflect that nuance, but instead it reflects the setting. Until the rates are equalized, or at least made more sensitive to patient need, the urban-rural divide in post-acute care will persist.
