What Medicare requires before a Main Line Health discharge from Lankenau, Bryn Mawr, or Paoli Hospital -- and the 48-hour window families often miss.
By Philly Senior Advisor Care Team — Hospital & Veteran Transitions Team · September 24, 2026
It usually happens on day two or three of the hospital stay, not day one. A hospital employee -- sometimes called a discharge planner, sometimes a case manager, sometimes a social worker, depending on which Main Line Health hospital your relative landed in -- stops by the room with a folder of paperwork and a question that sounds simple: where is the patient going next? At Lankenau Medical Center in Wynnewood, Bryn Mawr Hospital, or Paoli Hospital, that conversation can happen within 48 to 72 hours of admission, and families who haven't been through it before are often caught flat-footed, assuming they'll have a week or two to research options the way they would if they were choosing a facility on their own timeline.
That compressed timeline is not a Main Line Health quirk. It reflects how Medicare pays hospitals -- largely by diagnosis rather than by length of stay -- which gives every hospital in Greater Philadelphia, not just this one system, a financial incentive to move a medically stable patient toward the next setting quickly. Understanding that incentive doesn't make the discharge planner an adversary, but it does explain why the plan on offer is often the fastest safe option rather than the best-researched one, and why a family that wants a different personal care home, assisted living residence, or rehab facility usually has to say so out loud, more than once, to get real consideration.
Federal hospital rules require every Medicare-participating hospital, including all three Main Line Health facilities, to screen patients for discharge planning needs, involve the patient and family in developing the plan, and provide a list of Medicare-certified home health agencies, skilled nursing facilities, or other post-acute providers serving the area -- not just one recommendation. The hospital cannot require the patient to use its preferred or affiliated provider, and it cannot have a financial arrangement that steers the choice. Every Medicare inpatient also receives a signed notice called the Important Message from Medicare within 48 hours of admission, which explains discharge rights in writing, and a follow-up Detailed Notice of Discharge if the patient wants to formally contest the timing.
What the planner is not required to do is vet the quality of a specific personal care home or assisted living residence for you, negotiate a lower rate, or flag that a facility on the list has open violations. Pennsylvania's two licensing agencies keep that information publicly searchable -- the Department of Human Services for Personal Care Homes under 55 Pa. Code Chapter 2600 and Assisted Living Residences under Chapter 2800, and the Department of Health for nursing homes under 28 Pa. Code Chapter 211, cross-checked against Medicare's Care Compare tool. A discharge list with a facility's name and phone number is not the same as a clean inspection history, and families leaving any Main Line Health hospital should treat the two as separate steps.
Before the discharge conversation even starts, one earlier decision shapes everything: whether the hospital classified the stay as inpatient or as observation, a form of outpatient care that can happen in the same bed, with the same nurses, and still be billed differently. Medicare's traditional benefit only counts toward the three-inpatient-day threshold that can open the door to covered skilled nursing facility care afterward if the patient was formally admitted as an inpatient -- observation days generally don't count, no matter how many of them there were. Families frequently don't learn the classification until the discharge conversation, when it suddenly determines whether a rehab stay is a covered benefit or an out-of-pocket bill.
Any Main Line Health hospital is required to give a Medicare Outpatient Observation Notice, sometimes called a MOON, within 36 hours if a patient has been in observation status for more than 24 hours, explaining the classification and its financial consequences in writing. Asking the nurse or discharge planner directly -- 'has my relative been admitted as an inpatient, or is this still observation?' -- is a fair question at any point in the stay, and the answer changes what a family should be negotiating for at discharge.
Lankenau, Bryn Mawr, and Paoli Hospital sit along different stretches of Main Line Health's service area, and that geography quietly shapes which senior care options end up on a family's short list. A patient discharged from Lankenau in Wynnewood is often closest to Lower Merion Township and the eastern Main Line, with Philadelphia's western neighborhoods and Delaware County also in easy reach. Bryn Mawr Hospital sits in the heart of the Main Line corridor -- Bryn Mawr, Wayne, and Villanova -- where assisted living and personal care home rates tend to run toward the higher end of the region's range. Paoli Hospital serves the Chester County side, closer to Malvern, Downingtown, and West Chester, where per-month rates are often somewhat lower than the immediate Main Line towns but licensing rules are identical statewide.
That matters because a discharge list generated at one hospital doesn't automatically include every licensed option a family might prefer in a neighboring county. A patient discharged from Paoli Hospital, for instance, isn't limited to Chester County facilities -- a family can ask for options in Delaware or Montgomery County if that's where a spouse or adult child actually lives and can visit. The hospital's job is to provide a safe plan quickly, not necessarily the geographically ideal one, so naming a preferred town or county early in the discharge conversation is one of the more effective ways families change the outcome.
If a discharge date feels premature -- too soon after surgery, before a wound is stable, before a caregiver has actually lined up 24-hour coverage at home -- Medicare gives every inpatient the right to an immediate, free appeal before leaving the hospital. The mechanism runs through the Beneficiary and Family-Centered Care Quality Improvement Organization named on the Detailed Notice of Discharge the hospital provides, not through the hospital itself, which keeps the review independent. Filing the appeal by the deadline printed on that notice -- typically the day the notice is delivered -- means the patient cannot be billed for the extra hospital days while the independent review is pending, and cannot be discharged until a decision comes back.
This right exists for observation-status patients too, though the notice and process differ slightly, which is one more reason to ask about admission status early rather than discovering it at the door. Few families use this appeal, not because it doesn't work, but because almost nobody explains it exists until a discharge planner is already reciting it from a script during a stressful conversation. Writing down the QIO's phone number from the discharge folder before that conversation happens, rather than during it, is a small step that keeps the option usable under pressure.
A short set of questions, asked out loud to whoever from Lankenau, Bryn Mawr, or Paoli Hospital is running the discharge conversation, tends to change how much choice a family actually gets. Confirm in writing whether the stay was billed as inpatient or observation, since that single fact determines whether a subsequent rehab stay is a covered Medicare benefit. Ask for the full written list of post-acute providers, not a single verbal recommendation, and ask specifically whether facilities outside the hospital's immediate county are included. Request an extra day if the home isn't ready -- oxygen not delivered, a hospital bed not yet installed, home care not yet scheduled -- since Main Line Health, like every hospital, can authorize a short delay when the discharge plan genuinely isn't safe yet.
Before agreeing to any specific personal care home or assisted living residence named on that list, look it up independently through the Pennsylvania Department of Human Services' facility search for Personal Care Homes and Assisted Living Residences, or the Department of Health's search for nursing homes, rather than relying on the discharge folder alone. None of this requires confrontation -- it requires treating the discharge conversation as the start of a decision the family gets to make, not paperwork the hospital hands down. Families who ask these questions in the first conversation, rather than after signing, consistently end up with more workable placements and fewer surprises in the first week home.
