the new DN codes are 20560 for 1-2 muscles and 20561 for 3 or more. These are the codes to be used with DN but are not yet reimbursed by Medicare and many if not all of the commercial carriers. Elec. stim with needles is the same thing and not reimbursable I would suggest cash payment be taken. At some point they will assign a RVU to it and begin to reimburse but not sure what that amount will be and right now cash is not a bad option. I would not do needle Elect. Stim unattended.
