The Acute Hospital Care at Home (AHCAH) initiative, launched in November 2020 in response to the COVID-19 pandemic, allows Medicare-certified hospitals to treat patients with inpatient-level care at home. Data contained within the AHCAH data set was collected by CMS directly from individual hospitals on either a weekly or monthly basis depending on their participation tier, which is based on the level of experience the facility has with providing hospital at-home services.
The AHCAH dataset contains two files, a Hospital file and a Patient file, which are both provided for a research request (i.e., cannot be requested separately). The Patient file contains a record for each AHCAH admission for the patient, and includes other beneficiary-specific data such as the beneficiary’s program eligibility status (Medicare, Medicaid, Dual) and the state Medicaid identifier, if applicable. The file also contains the facility submission date for the data represented in the file record. The submission date represents the data submitted by the facility for the previous month.
Each file contains the monthly or weekly submitted data for each participating hospital for the time period from November 2020 through March 2023 (29 months). A second data release is planned for the future at a date to be determined.

The Medicare-Medicaid Linked Enrollee Analytic Data Source (MMLEADS) 3.0 suite of files combines Medicare and Medicaid enrollment and claims data into two annual beneficiary-level files. The files include beneficiaries who are Medicare-only, Medicare-Medicaid dually enrolled and Medicaid-only blind and disabled.
What is different about MMLEADS 3.0?
MMLEADS now consists of two files—a beneficiary summary file and single cost (i.e., payments) and use (i.e., claim counts) file that combines Medicare and Medicaid information. CCW Chronic Condition and other condition flags are no longer provided.
Source data
Medicare: FFS, PDE and MA
Medicaid: T-MSIS data
