The Us Core 3.1.1. Profile for implantable devices is too restrictive in its scope (implantable devices) for use by Payer in reporting devices (not just implantables) to members or other payers as part of the CMS Interoperability Final Rule and to providers (as part of the scope of PDex).  We have created a profile on the base Device resource that follows the US Core profile as closely as possible.  We request an exception regarding the use of US Core Profiles for this specific use case.
