Standard Analytical Files (Medicare Claims) - LDS
Alert September 8, 2017: All LDS Medicare claims file layouts have been updated to include new variables. Please see the revised data dictionaries below.
Alert May 5, 2016: CMS is pleased to announce that all researchers will be allowed to request LDS claims data on a quarterly basis. Historically, researchers have only been able to request annual extracts of Medicare claims data under the LDS request process. Researchers now have the option of requesting LDS claims on an annual or quarterly basis making it easier to do the important research that will lay the foundation for better quality and lower costs in the health care system.
LDS Standard Analytic Files (SAFs), also known as Medicare claims files, are available for each claim type (Inpatient, Outpatient, Skilled Nursing Facility, Home Health Agency, Hospice, Carrier and Durable Medical Equipment). Detailed file information can be found by viewing the data dictionaries below or visiting the Research Data Assistance Center (ResDAC) LDS File Information page (under Related Links).
Submitting a data request: Please follow the instructions on the DUA - Limited Data Sets page.
