What is the official "time" of admission do you use at your facility? Is it when the patient actually arrives on the unit, or when the doctor/LIP writes the order to admit to inpatient services? Keep in mind that there are times that a transfer patient may stay longer where they are coming from e.g., in the ER or another facility, and the admitting doctor or LIP already placed the admitting orders.
Is there a CMS rule on this and if so, where can I find it?
Thank you,
