• 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.
