First, there are many different jurisdictions. CMS (Medicaid and Medicare) is a federal jurisdiction. Your state is also a separate jurisdiction. Your county and city are separate jurisdictions. You may have to deal with Joint Commission for accreditation, the Veteran’s Administration, or others.
Each jurisdiction and every funding organization may have their own rules for you to follow. Fortunately, most require compliance with the same NFPA standards as are required by CMS, albeit later editions.
This can be an advantage for you. Most cities require compliance with International Building Code and International Fire Code. Usually these codes will be 2006 editions or later. That means the NFPA 101, 110, 70, 70E, 110, 99, and 37 standards IBC and IFC require are the same as the CMS requirements just later editions. As a result, if your system was installed according to local municipal law you will be in compliance with CMA requirements as far as the physical equipment and installation are concerned.
Because of the IBC and IFC, if you are cited for a violation of installation or equipment, you may have recourse against your contractor or engineer. In other words, they may have to help you pay for the corrections.
If you are cited for an inspection, testing, or performance problem that will probably be something you will have to correct and pay for in-house.
