  1. 2008 Basic Stand Alone Carrier Line Items PUF

    The CMS 2008 BSA Carrier Line Items PUF originates from a 5% simple random sample of beneficiaries drawn (without replacement) from the 100% Beneficiary Summary File for reference year 2008. The sample that is used for the CMS 2008 BSA Carrier Line Items PUF is disjoint from the existing 5% CMS research sample. That is, there is no overlap in terms of the beneficiaries in the CMS 2008 BSA Carrier Line Items PUF and the 5% CMS research sample. The Carrier claims file was originally called the Physician/Supplier Part B file. This file contains final action claims data submitted by non-institutional providers. Each record in the Carrier claims file is a claim. Each carrier claim must include at least one Health Care Procedure Classification Code (HCPCS code) to describe the nature of the billed service. Each HCPCS code on the carrier bill must be accompanied by a line item ICD-9 diagnosis code, providing a reason for the service. In addition, each line item has the fields for the dates of service, reimbursement amount, provider numbers (e.g., NPI), and beneficiary demographic data. Each claim is comprised of up to 13 line items, each of which corresponds to one HCPCS code and its accompanying information.

  5. 2008 Basic Stand Alone Inpatient Claims PUF

    This is a Public Use File of Inpatient Claims drawn from the 2008 Beneficiary Summary File of Medicare beneficiaries enrolled during the calendar year 2008, and their associated Medicare claims. The most important aspects of this file are as follow: 1. It contains claims for a simple random sample of 5% of the 2008 beneficiary population. Out of approximately 2.4 million beneficiaries in the 5% sample, about 350,000 had claims (after excluding a relatively small fraction of ineligible claims), resulting in a Public Use File of just under 590,000 claims. 2. It contains six (6) analytic variables (in addition to an encrypted claim key): Age, gender, base DRG code, ICD-9 code, claim cost, and length of inpatient stay. All of these variables, except gender, have been suitably aggregated or averaged in order to protect individuals from identification, while retaining the analytic value of the data. 3. A claim for a sampled beneficiary is only included in the PUF if the combination of all six (6) variables is shared by at least eleven (11) claims pertaining to at least eleven (11) distinct beneficiaries in the population (but not necessarily the sample). 4. Claims cannot be linked by beneficiary, and cannot be linked to any external data source by means of the claim ID. The claim ID is a cryptographic key specific to this Inpatient Claims PUF and not available elsewhere. The inpatient Claims PUF is sorted by this claim ID to ensure that the relative position of claims in the PUF and the original source data are totally uncorrelated.

  9. 2008 Chronic Conditions PUF

    The 2008 Chronic Conditions PUF is an aggregated file in which each record is a profile or cell defined by the characteristics of Medicare beneficiaries. A profile is defined by all combinations of age category, gender, various chronic conditions, and dual-eligibility status of the beneficiaries. Hence, the number of rows (or records) in the CMS 2008 Chronic Conditions PUF represents the number of unique profiles in the Medicare population. For each profile many claim-related variables are provided in the form of averages. The CMS 2008 Chronic Conditions PUF represents 100% of the Medicare beneficiaries provided in the 100% Beneficiary Summary File for reference year 2008. The 100% Beneficiary Summary File is created annually and contains demographic, entitlement and enrollment data for beneficiaries who were: documented as being alive for some part of the reference year of the Beneficiary Summary File, are entitled to Medicare benefits during the reference year, and enrolled in Medicare Part A and/or Part B for at least one month in the reference year.

  15. Adverse Event Reporting System (AERS)

    The Adverse Event Reporting System (AERS) is a computerized information database designed to support the FDA's post-marketing safety surveillance program for all approved drug and therapeutic biologic products. The FDA uses AERS to monitor for new adverse events and medication errors that might occur with these marketed products. Reporting of adverse events from the point of care is voluntary in the United States. FDA receives some adverse event and medication error reports directly from health care professionals (such as physicians, pharmacists, nurses and others) and consumers (such as patients, family members, lawyers and others). Healthcare professionals and consumers may also report these events to the products' manufacturers. If a manufacturer receives an adverse event report, it is required to send the report to FDA as specified by regulations. The files listed on this page contain raw data extracted from the AERS database for the indicated time ranges and are not cumulative. Users of these files need to be familiar with creation of relational databases using applications such as ORACLE, Microsoft Office Access, MySQL and IBM DB2 or the use of ASCII files with SAS analytic tools. A simple search of AERS data cannot be performed with these files by persons who are not familiar with creation of relational databases.
