|Dataset Full Name||Durable Medical Equipment file|
|Summary||The Durable Medical Equipment file (DME) contains information on prescribed durable medical equipment provided to Medicare beneficiaries and the reason for the prescription (ICD-9 diagnostic codes for individual receiving the devices). Beneficiaries with Part B coverage are eligible to get DME for medical reasons and home usage. DME includes equipment such as: Air-fluidized beds, Blood sugar monitors and diabetic testing strips, Continuous Positive Airway Pressure machine, Home oxygen equipment, Hospital beds, Infusion pumps, Nebulizers, Patient lifts, Suction pumps, Traction equipment, Canes, Crutches, Commode chairs, Walkers, Wheelchairs, Prosthesis and orthotics. Equipment is identified using the Healthcare Common Procedure Coding System (HCPCS). The file also contains information regarding the provider number of the DME supplier, and the amount reimbursed by CMS to the supplier.|
