Scully then reentered private practice with the Washington, D.C. law firm of Patton Boggs, LLP, where he focused on regulatory and legislative work in health care.

Scully played a pivotal role in the development and design of the proposal, and led the administration's effort to craft the final in bill in Congress.

The next step for the program was the publication of performance by nursing homes nationwide on 10 measures ranging from the percentage of residents with pressure sores to those in physical restraints.

Critics of the program complained that nursing homes were being asked to do additional work in order to report the measures while they were dealing with funding cutbacks.

Scully also initiated a broad public education campaign to improve seniors’ awareness and utilization of their Medicare benefits.

On July 1, 2001, Scully presided over his agency's name change: the Health Care Financing Administration would now be called the Centers for Medicare and Medicaid Services, or CMS.

In 2015, Scully led the investment and development in Innovage, the country's largest and leading Program of All-Inclusive Care for the Elderly (PACE).

He also serves on the boards of InnovAge, Health Management Academy, Emerus, Select Medical, and the Columbus School of Law at Catholic University.
