SUPPLEMENTARY INFORMATION:

The OPEN Government Data Act requires Federal agencies to make public data assets available in open formats and under open
licenses, consistent with applicable law. CMS has advanced the release of provider prices and negotiated rates through its
positions on provider price transparency, most recently promulgated through the Calendar Year 2026 Hospital Outpatient Prospective
Payment System (OPPS) and Ambulatory Surgical Center Final Rule (CMS-1834-FC). CMS is committed to advancing transparency
while ensuring compliance with all applicable legal requirements and privacy considerations governing the disclosure of Federal
data.

CMS has made available the following public data assets with utilization and payment data aggregated by provider and service:

Original Medicare Physician & Other Practitioners—By Provider and Service
Original Medicare Inpatient Hospitals—By Provider and Service
Original Medicare Outpatient Hospitals—By Provider and Service
• Medicare Part D Prescribers—By Provider and Drug
Original Medicare Durable Medical Equipment, Devices and Supplies (DMEPOS)—By Referring Provider and Service
Original Medicare Durable Medical Equipment, Devices and Supplies (DMEPOS)—By Supplier and Service
Medicaid Provider Spending—By Provider and Service (including aggregated managed care payment data elements, with disclosure
avoidance techniques applied)
CMS has evaluated prior Agency statements and the disclosure of the datasets included in this notice consistent with applicable
legal requirements. CMS considered applicable privacy protections under the Health Insurance Portability and Accountability
Act of 1996, as amended by the Health Information Technology for Economic and Clinical Health Act, and relevant provisions
of the 21st Century Cures Act. Where applicable, CMS also considered confidentiality requirements for substance use disorder
information under 42 CFR part 2. Based on this assessment, CMS has determined that the datasets have been de-identified and
appropriately limited to mitigate the risk of re-identification, do not disclose protected trade secret or confidential commercial
information and are appropriate for public release.

CMS will continue to evaluate additional datasets, as well as applicable governing laws and regulations, as it prepares future
data releases.
