Found my issue, I had the execute query command in the code twice. Found that and resolved the issue.

got it to work, but there might be a better solution, if so, please comment

ClassMethod EditSurgery() As %Status
{
    S EditData={}.%FromJSON(%request.Content)
    w !,EditData.SurgeryCase,!
    #Dim otherProc As %DynamicObject
    s otherProc=EditData.OtherProcedures
    s iterator=otherProc.%GetIterator()
    while iterator.%GetNext(.key, .OtherProcedure) {
        set type = otherProc.%GetTypeOf(key)
        s name=otherProc.%Get(key).OtherProcedure
        s cpt=otherProc.%Get(key).PlannedOtherProcCPTCode
        s comment=otherProc.%Get(key).ProcedureCodeComments
        w !," name= ",name," cpt= ",cpt," comments= ",comment
    }

    q 200
}
