New York State announced that most Health Commerce System (HCS) functions will require supported operating systems and browsers as of June 1, 2017. Specifically, as of June 1, Windows XP and/or Internet Explorer ver. 9 (and older) will no longer have access to the HCS. The NYS HCS is used for the I-Stop and PMP (Prescription Monitoring Program), for which access is required when prescribing controlled substances.
Newer Microsoft Windows operating systems and Internet Explorer versions may be used after June 1, as can alternate operating systems and browsers (including Apple Mac OS, and Google Chrome).
