Rehab After Hospital Stay Missouri: Medicare Coverage and Costs

How Medicare Covers Rehabilitation After a Hospital Stay

When a parent is discharged from a Missouri hospital and needs physical therapy, occupational therapy, or skilled nursing care to recover, Medicare Part A can cover rehabilitation at a skilled nursing facility (SNF). The coverage follows a structured timeline with specific eligibility requirements and cost-sharing rules.

To qualify, the patient must have had a medically necessary inpatient hospital stay of at least three consecutive days. The transfer to the SNF must occur within 30 days of hospital discharge, and the rehabilitation must be for a condition treated during the hospital stay or that arose during the stay.

The 100-Day Rule: What It Actually Covers

Medicare Part A covers up to 100 days of skilled nursing facility care per benefit period. But the coverage is not uniform across all 100 days:

• Days 1-20: Medicare covers the full cost with no copay from the patient.
• Days 21-100: The patient owes a daily coinsurance amount — $204.00 per day in 2026. For a 30-day stint in days 21-50, that adds up to $6,120 in out-of-pocket costs.
• After day 100: Medicare coverage ends entirely. The family is responsible for the full daily rate, which averages $250 to $400 per day at Missouri facilities.

Most Medicare beneficiaries do not use the full 100 days. The average SNF stay is closer to 25 to 30 days. The critical planning window is anticipating the day-21 copay and deciding when to transition from facility-based rehabilitation to home-based care.

When Medicare Stops Paying: The Improvement Standard Myth

Skilled nursing facilities sometimes tell families that Medicare will stop covering rehabilitation once the patient stops showing improvement. This is wrong, and it was settled by the Jimmo v. Sebelius case in 2013.

Under the Jimmo settlement, Medicare covers skilled services needed to maintain a patient's current condition or to prevent decline — not just services aimed at improvement. If your parent has Parkinson's disease and needs ongoing physical therapy to maintain their current mobility level, that therapy is covered as long as it requires the skills of a trained therapist.

If a facility claims Medicare will not cover maintenance therapy, request the specific clinical documentation supporting the decision and consider filing an appeal through Commence Health (1-888-755-5580).

Choosing a Rehabilitation Facility in Missouri

The hospital discharge planner must provide a list of Medicare-certified skilled nursing facilities in the area. Families should evaluate these facilities using:

• Medicare's Care Compare tool — provides star ratings based on health inspections, staffing levels, and quality measures
• Missouri state survey reports — managed by the Section for Long-Term Care Regulation, these reports detail inspection findings and citations
• Staffing ratios — ask the facility for their current registered nurse-to-patient ratio, particularly on evenings and weekends when staffing typically drops

Do not let time pressure force you into the first available facility. If the preferred facility does not have an immediate bed, the hospital must continue to provide care until a safe transfer can be arranged.

Transitioning from SNF to Home-Based Care

As your parent approaches the end of their SNF rehabilitation stay, the transition home requires coordination on multiple fronts:

Medicare home health: If your parent is homebound and needs ongoing skilled nursing visits or therapy, the SNF physician can order Medicare-certified home health services to continue after discharge. These services are covered under Medicare Part A with no copay, as long as the patient meets the homebound criteria.

Missouri HCBS programs: If your parent needs daily personal care assistance — bathing, dressing, meal preparation — beyond what Medicare home health covers, Missouri's Home and Community-Based Services through the Division of Senior and Disability Services (DSDS) can authorize paid attendants. The parent must meet MO HealthNet eligibility requirements and score at least 18 points on the InterRAI HC assessment.

Consumer Directed Services (CDS): This Missouri program allows the parent to hire their own care attendant, including family members (excluding spouses and legal guardians). The CDS application process should be initiated before SNF discharge to avoid a gap in care coverage.

The Missouri Hospital Discharge Guide maps the complete SNF-to-home transition, including a timeline for initiating DSDS referrals, the CDS enrollment process, and home safety modifications to prepare before the parent arrives.
