Long-Term Care Minimum Data Set (MDS) Files

Medicare

Description

Our Long-Term Care Minimum Data Set (MDS) files have long-term care beneficiaries' responses to health status screening and assessment questions. These files also have long-term care providers' evaluations of long-term care beneficiaries' health.

More specifically, the files have the following information:

  • beneficiary demographics;
  • cognitive health status;
  • diagnosis codes;
  • diagnosis codes;
  • mood status;
  • physical evaluations;
  • procedure codes;
  • processing codes;
  • provider characteristics;
  • service dates; and
  • social behavior.

There are two types of MDS data: nursing home and swing beds. Both types of data have two versions:

  • Version 2.0, which covers 1999 to 2010.
  • Version 3.0, which covers 2010 to now.

NOTE: We do not currently offer MDS swing-bed data; however, we do offer MDS nursing home data.
