When can we start using the new E/M rules for new and established patient visits? And, are all payers going to follow them?
The revised definitions for codes 99202—99215 are effective until January 1 2021. These new definitions are now in the 2021 CPT book.
CMS and the AMA have joined hands (figuratively speaking) in these new definitions for new and established outpatient services.
The AMA says that commercial payers are on board with these changes. Use them for all payers.
