The April release of Medicare’s vast trove of payment data has triggered a torrent of reports illustrating just how useful this data can be for patients and providers. While many of the articles have focused on how much Medicare pays doctors, the data have also provided valuable context for broader pieces on the state of American health care.

In a major win for transparency, the Centers for Medicare and Medicaid Services (CMS) announced on April 2 that it will release physician reimbursement data. This data, previously kept confidential, contains information about how much the federal government pays to most Medicare providers. The data will not compromise or disclose any patient privacy information.

On March 14, the House passed the SGR Repeal and Medicare Provider Payment Modernization Act (H.R. 4015), which includes provisions on Medicare data transparency. Among other things, the bill would require Medicare to publicly disclose data on reimbursements made to physicians while protecting patients' privacy. The legislation would direct the Secretary of Health and Human Services to release payment data on Physician Compare, the Center for Medicare and Medicaid Services' online physician database. Unfortunately, the bill also contains a "poison pill" – the repeal of the Affordable Care Act's individual mandate – rendering it unworkable in its current form.

On Jan. 14, the Centers for Medicare & Medicaid Services (CMS) announced a new policy that could bring greater transparency to Medicare, one of the largest programs in the federal government. CMS revoked its long-standing policy not to release publicly any information about Medicare’s payments to doctors. Under the new policy, the agency will evaluate requests for such information on a case-by-case basis. Although the impact of the change is not yet clear, it creates an opportunity for a welcome step forward for data transparency and open government.
