This variable is the count of hospital stays (unique admissions, which may span more than one facility) in the non-acute inpatient setting for a given year. A non-acute inpatient stay is defined as a set of one or more consecutive non-acute inpatient claims where the beneficiary is only discharged on the most recent claim in the set. The CLM_FROM_DT for the first claim associated with the stay must have been in the year of the data file, however it was permissible for the CLM_THRU_DT to have occurred in January of the following year.
These “other” inpatient (OIP) claims are a subset of the claims in the IP data file consisting of data from IP settings such as long-term care hospitals, inpatient psychiatric facilities, inpatient rehabilitation facilities, and other types of IP facilities such as children’s hospitals or cancer centers.
There are 2 cost/use categories from the IP data files: Acute and the OIP
