Provider Specific File
The Provider Specific File contains data related to PPS payment
such as number of beds and interns-to-bed ratio, for all PPS-eligible
hospitals. This information is used along with the Diagnosis Related Group
(DRG) by the PPS pricing mechanism software, called PRICER, to calculate
Medicare PPS payment for inpatient hospital claims. Further discussion
of PPS can be found in the Overview of the Health Care Financing Administration
chapter in the Orientation Section.
File Creation 
Fiscal Intermediaries (FIs) maintain provider specific information for
the purpose of calculating inpatient hospital claim payment amounts under
PPS. FIs obtain the values for some provider specific data elements such
as number of beds from the hospitals and other data elements such as the
case-mix index from CMS(previously HCFA). Every quarter, FIs send CMS a tape containing
current and historic provider specific data. From these data CMS creates
a file containing only the most recent data; data for previous quarters
are stored in historical files. The Provider Specific File contains data
for all PPS-eligible hospitals, including hospitals in waiver States.
It does not include data for facilities that are specifically excluded
from PPS, such as children's and cancer hospitals. The Provider Specific
File has been created and maintained quarterly since October 1, 1983,
the beginning of PPS. The file created for the fourth quarter of every
fiscal year is referred to as an annual file.
File Maintenance 
The Provider Specific File provides a snapshot of provider data at a
certain point in time. All quarterly data submissions are maintained.
When CMS receives a quarterly file from an FI, it performs completion
checks and edits the record for conformity to provider number ranges,
code ranges, minimum and maximum dollar amounts, and other data parameters.
CMS also adds new information to the file such as changes in Metropolitan
Statistical Area. FIs are alerted when submissions are incomplete or contain
errors and are required to resubmit a corrected version of the file.
File Structure and Usage 
The Provider Specific File contains provider specific information used
by FIs to calculate PPS inpatient hospital claim payments. The information,
which does not appear on the Medicare claims directly, includes intern-to-bed
ratio; pass-through amounts for capital, direct medical education, and
organ acquisition; and the number of hospital beds. The Provider Specific
File is also used by the FIs to verify a provider's status against incoming
claims. Providers can use provider specific data to calculate their own
claim payment amounts, or to compare their pricing information to that
of other PPS providers. The provider is the unit of analysis.
Data Structure and Usage 
The Provider Specific File contains approximately 5,600 records: one
record for each PPS-eligible hospital, including hospitals in waiver States.
The records are ordered by provider number. Each fixed length record contains
approximately 40 data elements including nine data elements that were
added to the record when capital rates were incorporated into PPS in October
of 1991.
Methods of Access 
The Provider Specific File is available as a sequential flat file or
SAS data set. A public use version of the Provider Specific File is described
in the Public Use Files Data chapter.
Migration of Data 
The Provider Specific File has not changed except to add capital rates
data in 1991.
List of Data Elements 
A list of the data elements contained in the Provider Specific File,
along with brief definitions and coding schemes, will be included in the
future on the CMS web site at www.cms.hhs.gov.
