After a hip fracture, one hospital label can change what Medicare pays
Mom fell. The hip is broken. Surgery is tomorrow. In the rush, nobody mentions the word that shapes the next few months: is she inpatient, or "under observation"? That label, and where she goes after the hospital, decide what Medicare covers. Once you know to ask, you are a step ahead of the paperwork.

The first two days move fast, on purpose
Most hip fractures are repaired with surgery. The surgeons' patient site says surgery within 24 to 48 hours may lower the risk of complications.
Then comes the surprise: most patients get out of bed and start physical therapy the day after surgery. That is the plan, not a rush. Long stretches in bed are risky for an older adult: bed sores, blood clots, pneumonia, and confusion. Getting up early is part of the treatment.
INSIDER TIP
Families often spot confusion first. If your parent seems "not themselves", tell the nurse right away. You know their normal. The staff met them yesterday.
The label that decides the nursing-facility bill
"Inpatient" or "observation" sounds like paperwork. It is the switch that matters most. Original Medicare covers a skilled nursing facility only after an inpatient stay of at least 3 days in a row. The admission day counts. The discharge day doesn't.
Here is the catch. Time under observation, or in the emergency room before admission, doesn't count toward those 3 days. A parent can spend days in a hospital bed and still not qualify. Ask on day one, and ask again before discharge. Our answer explains why: Inpatient or "under observation": why does it matter?
Planning for the next step can start soon after surgery. Find the case manager or social worker early. Tell them what home really looks like: stairs, who lives there, who can help and when.
Three places to go next, three sets of rules
The next setting depends on how much your parent can do alone and how much help waits at home. The names get mixed up, but the rules don't:
- Inpatient rehab. Intensive therapy with medical supervision. Medicare covers it when a provider certifies your parent needs that level of care.
- A skilled nursing facility (SNF). Short-term care and therapy at a slower pace. Under Original Medicare it needs the 3-day inpatient stay, you generally go within 30 days of leaving the hospital, and coverage stops at 100 days per benefit period (one stretch of care).
- Home, with home health. If your parent is homebound (can't easily leave the house) and needs skilled care, Medicare can bring therapy to the door. Our guide: Medicare home health.
How to weigh them: Rehab, nursing facility or home: how do we choose? What it looks like when the plan and the place don't match: We thought it was rehab. It was a nursing home. And for what therapy does and what Medicare pays after discharge: PT and OT after an injury.
Questions to ask:
- To the hospital team: "Is my parent inpatient or under observation? Since what date?"
- To the case manager: "Which next step do you recommend, and why?"
- To the facility: "How many hours of therapy a day, and who pays for it?"
WHERE THIS COMES FROM
The 3-day rule, observation days, the 30-day window and the 100-day limit are from Medicare.gov's skilled nursing facility page. Inpatient rehab conditions are from Medicare.gov's inpatient rehabilitation page. Medicare Advantage plans can have different rules, so call the plan too.
Home, and the next fall
Most people come home on a walker or crutches. The national medical library suggests a bedroom and bathroom on the first floor, a bed low enough for feet to touch the floor, a clear path with no loose rugs or cords, and grab bars by the toilet and shower.
Call the surgeon about one leg that is swollen, red and warmer than the other, or calf pain. Those can be signs of a blood clot. Shortness of breath or chest pain needs urgent care.
A hip fracture is also a signal. One fall doubles the chance of another. Bones weakened by osteoporosis (thin, fragile bone) can break in a minor fall. Ask the primary doctor: "Should we check fall risk, review medicines that cause dizziness, and look at bone density now?" Leg strength, balance work like tai chi, and a yearly eye exam help too.
The 60-second recap
- Surgery usually comes within 1 to 2 days, and therapy starts the day after.
- Ask early and often: inpatient or observation? Observation days don't count toward Medicare's 3-day rule.
- Inpatient rehab, a nursing facility and home health have different rules. Know which one you're getting.
- After one fall, the next is more likely. Fall risk, medicines and bone health are worth a conversation now.
