Mostashari stopped short of supporting alterations to the 2014 final rules or deadlines laid out in the final rules published in 2012.
"There's no legal way to change a final rule without doing a pretty involved process," Mostashari told the CHIME audience. "It takes about nine to 12 months of proposing the new rule, getting that cleared through OMB, getting public comment on it, and all the stuff you guys have been through with Stage 1 and Stage 2. It would be total chaos."
Delaying implementation of the Meaningful Use 2014 and Stage 2 rules would also negatively impact programs such as the IQR, PQRS, and ACO initiatives at CMS. "We've worked really hard to align them, and if you take this out, that alignment falls apart," Mostashari said.
"You can't then use the Meaningful Use quality reporting to count towards PQRS and IQR and ACO… I think folks should assume that the timelines stick."
On Oct. 3, Mostashari accepted a position as visiting fellow and vice president and director of economic studies at the Engelberg Center for Health Care Reform at The Brookings Institution, a Washington D.C.-based think tank.
