Defining a Short-Term Skilled Nursing Facility Stay Under Medicare Part A
Short-term rehabilitation in a nursing home refers to a medically supervised recovery stay at a skilled nursing facility (SNF) following a qualifying hospital admission. Medicare Part A covers this benefit under specific conditions. The patient must have been admitted to an acute care hospital as an inpatient for at least three consecutive days, not counting the day of discharge. The SNF admission must occur within 30 days of that hospital discharge, and the patient must require skilled care such as physical therapy, occupational therapy, speech-language pathology services, or skilled nursing procedures.
Medicare Part A does not cover custodial care, meaning assistance with activities of daily living that does not require a licensed clinician. The distinction between skilled and custodial care is central to eligibility and is evaluated on an ongoing basis throughout the stay. Common qualifying conditions include recovery from hip or knee replacement surgery, stroke rehabilitation, cardiac events, and orthopedic fractures.
Under the Medicare SNF benefit, coverage is structured around benefit periods. During days 1 through 20, Medicare covers 100 percent of approved costs. From days 21 through 100, the patient is responsible for a daily coinsurance amount, set at $204.00 per day in 2024. After day 100, Medicare coverage ends entirely for that benefit period.
Types of Therapy Provided During Short-Term Rehabilitation
SNFs offering short-term rehabilitation typically provide three categories of restorative therapy, each addressing different functional deficits.
- Physical therapy (PT) focuses on restoring mobility, strength, balance, and gait. Therapists address transfers, ambulation, stair climbing, and fall prevention. PT is commonly prescribed after orthopedic surgery or neurological events such as stroke.
- Occupational therapy (OT) targets the ability to perform activities of daily living, including bathing, dressing, grooming, and meal preparation. OT may also address fine motor skills and adaptive equipment training to support safe discharge to home or a lower level of care.
- Speech-language pathology (SLP) covers swallowing disorders (dysphagia), cognitive-communication deficits, and speech impairments. SLP services are frequently required following stroke, traumatic brain injury, or head and neck surgery.
Therapy sessions are typically delivered five to seven days per week during an acute SNF stay. The frequency and duration of services are determined by clinical need and documented in the care plan, which is reviewed regularly by the interdisciplinary team.
The Minimum Data Set Assessment and Its Role in Care Planning and Billing
The Minimum Data Set (MDS) is a standardized federal assessment tool used in all Medicare and Medicaid certified nursing facilities. It captures clinical, functional, and cognitive information about each resident and serves two primary functions: informing individualized care planning and determining Medicare payment rates.
MDS assessments are completed by licensed nursing staff and must follow a federally mandated schedule. For SNF stays under Medicare Part A, assessments are required at specific intervals, including days 5, 14, 30, 60, and 90 of the stay. Each assessment captures data on the resident's functional status, therapy utilization, medical complexity, and care needs.
The data collected through the MDS feeds directly into the Medicare Prospective Payment System. Errors or incomplete documentation in the MDS can affect both the accuracy of care planning and the reimbursement rate the facility receives. The Centers for Medicare and Medicaid Services (CMS) uses MDS data for quality monitoring, public reporting on Nursing Home Compare, and regulatory oversight.
How the Medicare Prospective Payment System Works for SNF Stays
Since October 2019, Medicare has reimbursed SNF stays using the Patient-Driven Payment Model (PDPM), which replaced the prior Resource Utilization Group (RUG-IV) system. Under PDPM, payment rates are calculated based on the clinical characteristics of the patient rather than the volume of therapy minutes delivered. This shift was intended to align payment with patient need and reduce incentives for providing excessive therapy services.
PDPM uses five case-mix adjusted components to calculate a daily rate for each patient. These components are physical therapy, occupational therapy, speech-language pathology, nursing, and non-therapy ancillary services. Each component has its own payment rate, and the rates are derived from information documented in the MDS assessment.
The base payment rates vary by facility wage index and are updated annually through the federal rulemaking process. For fiscal year 2024, CMS increased SNF payment rates by approximately 4.0 percent. The daily rate for a given patient can range broadly depending on clinical complexity, from roughly $400 to over $900 per day in total Medicare reimbursement, with more medically complex patients generating higher rates.
Discharge Planning and the Transition From Medicare Coverage
Discharge planning for short-term SNF stays typically begins at or near the time of admission. Federal regulations require SNFs to conduct discharge planning for all residents and to involve the patient and family in the process. The interdisciplinary care team, which may include nursing staff, therapists, social workers, and the attending physician, identifies the anticipated discharge destination, evaluates home safety, and arranges any necessary follow-up services.
Common discharge destinations include return to home with home health services, transfer to an assisted living facility, or continued residence in the nursing home under a long-term care arrangement. Home health services following SNF discharge may include skilled nursing visits, continued physical or occupational therapy, or aide assistance, and may be covered under Medicare Part A or Part B depending on circumstances.
When Medicare coverage ends, either because the patient no longer requires skilled care or has exhausted the 100-day benefit, payment responsibility shifts. Patients with Medicaid eligibility may transition to Medicaid-funded long-term nursing home coverage if they meet both clinical and financial criteria. Medicaid eligibility thresholds vary by state, but generally require the applicant to have limited assets and income. Patients who do not qualify for Medicaid must pay privately, with nursing home costs averaging approximately $9,500 per month for a semi-private room nationally, based on 2023 survey data from Genworth Financial.
The Right to Appeal a Discharge Decision: The NOMNC Process
Medicare beneficiaries receiving SNF care have a federally protected right to appeal a facility's determination that skilled care is no longer necessary. This right is governed by the Notice of Medicare Non-Coverage (NOMNC) process, administered through Beneficiary and Family Centered Care Quality Improvement Organizations (BFCC-QIOs).
When a SNF determines that a patient's Medicare-covered stay will end, the facility is required to provide written notice at least two days before coverage is scheduled to stop. This notice, the NOMNC, informs the patient of the last covered day and explains the right to request an expedited appeal. To initiate an appeal, the patient or authorized representative must contact the applicable BFCC-QIO by noon of the day before the stated termination date.
Upon receiving a timely appeal request, the QIO must conduct an independent clinical review and issue a decision within one business day. If the QIO rules in the patient's favor, Medicare coverage continues. If the QIO upholds the discharge, the patient retains the right to further appeal through the ALJ (Administrative Law Judge) process, the Medicare Appeals Council, and ultimately federal district court. During a pending QIO review, the patient is not financially liable for SNF costs, provided the appeal was filed within the required timeframe.
Patients and families are advised to retain copies of all NOMNC notices and to document communications with facility staff regarding discharge planning, as these records may be relevant if an appeal proceeds to higher levels of review.
