CMS did not change the logic for comprehensive APCs (C-APC) or complexity adjustments in the 2016 OPPS final rule, but did add 10 new C-APCs for 2016 in addition to the 25 established for the first time for 2015.
I first attended a lecture on the "upcoming" ICD-10 changes that were expected in 1991 (when the rest of the world started transitioning). On October 1, 2015, a mere 24 years and countless lectures later, the U.S. finally adopted ICD-10 (via ICD-10-CM and PCS, which are both unique to the U.S. at this time).
CMS finalized its proposals regarding the 2-midnight rule, including moving responsibility for rule enforcement and education from Recovery Auditors to Quality Improvement Organizations (QIO). This latter change occurred October 1, 2015.
Providers often struggle with modifiers‑even those they've had available to report for many years‑due to the unique scenarios they face at their facilities, staffing changes, and/or unclear or lacking authoritative guidance.
The 2016 OPPS final rule includes the first negative payment update for the system, but CMS also listened to commenters' suggestions to make a variety of proposals less onerous either operationally or financially.
