|Dataset Full Name||Medicare Provider Analysis and Review|
The MEDPAR file contains utilization of services and claims data for Medicare beneficiaries during their stay in Medicare-certified inpatient short-term hospitals, skilled nursing facilities, inpatient rehabilitation facilities, and long-term care hospitals. The data are available in two formats: a 5% format that contains a random selection of 5% of total Medicare beneficiaries, and a 100% sample.
These records are all from inpatient facilities (Part A) and do not have any information related to outpatient care (Part B). The claims data in MEDPAR are final after taking into account all adjustments. The dataset is useful for tracking patterns of inpatient care for patients with various medical conditions. It also contains information related to the medical and surgical procedures that patients underwent during their stays in inpatient facilities.
