Hospital Ownership Records from Medicare and Medicaid Providers

This dataset lists all owners of hospitals enrolled in Medicare and Medicaid programs. It includes ownership name, type, address, and effective date, sourced from the Provider Enrollment, Chain and Ownership System (PECOS). The data is self-reported by the entities and is intended to be used with corresponding hospital enrollment records.

Use Cases

• Analyze ownership type distribution across the hospital network to identify common corporate structures.
• Link ownership name and address data with external datasets to study geographic concentration of hospital owners.
• Track changes in hospital control by examining ownership effective date timelines.
• Validate self-reported ownership information against other regulatory filings for data quality checks.

Strengths

• Data originates from the authoritative PECOS system managed by the U.S. Centers for Medicare and Medicaid Services.
• Includes multiple ownership attributes such as name, type, address, and effective date for linkage analysis.
• Maintained by a U.S. federal agency, suggesting structured collection processes.

Limitations

• Data is self-reported by entities, which may introduce inaccuracies or inconsistencies.
• Row count, file formats, and specific column definitions are unknown, limiting initial assessment of scope and usability.
• Must be joined with a separate Hospital Enrollments dataset to obtain full hospital details, requiring additional data management.
