Received following response in regards to MA providers: "Good Afternoon,  As previously advised Stacie and I can address questions regarding RI only and as stated you are able to bill Prisca Hefti for Supervisory Protocol. Please be aware that all claims billed by non-licensed providers should be billed under the applicable supervisor (which may not necessarily all be under Prisca Hefti ). If you have additional providers to be credentialed in the roll of Supervisor that have yet to be for RI please let us know.
