In a letter to Centers for Medicare and Medicaid Services (CMS) Administrator Seema Verma, Partnership to Improve Patient Care (PIPC) Chairman Tony Coelho expressed his concerns about the latest proposal to the Medicare Shared Savings Program to remove the requirement to submit supporting documentation related to patient-centeredness in their applications. "We are concerned that CMS would propose to remove these requirements and accept attestation in their place," said Chairman Coelho. "Although we understand that CMS is attempting to lessen the burden on ACO applicants, we believe that it is imperative that ACOs be held to the highest possible standard for patient-centeredness."
