This variable indicates the total amount paid for other (non-acute) inpatient stays by a primary payer other than Medicare. It is the sum of all the primary payer amounts (NCH_PRMRY_PYR_CLM_PD_AMT from each claim) in the other inpatient hospital settings for the 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.
This variable was new in 2010; it will always be null/missing in earlier files.
There are 2 cost/use categories from the IP data files: Acute and the OIP.
Medicare payments are described in detail in a series of Medicare Payment Advisory Commission (MedPAC) documents called “Payment Basics” (see: http://www.medpac.gov/-documents-/payment-basics).
Also in the Medicare Learning Network (MLN) “Payment System Fact Sheet Series” (see the list of MLN publications at: http://www.cms.gov/Outreach-andEducation/Medicare-Learning-Network-MLN/MLNProducts/MLN- Publications.html)
