If the patient is not getting any therapy, only skilled nursing, The earliest I would do a 5th day PPS assessment is on the 7th day just to capture 7 days of any nursing service...example, respiratory treatments. If the patient is on rehab they generally do it on the 7th or 8th day to capture at least 5 days of treatment if the orders for therapy are for 5x/week. The therapy manager didn't have to be semi nasty about it though! :)
