I noticed that you have suggested coding appliances (sleep apnea, etc.) using 21089 for the appliance and 99002 for the handling. Per the CPT- 21089 should only be used when the physician actually designs and prepares the prosthesis (no outside lab)while 99002 is used for the handling, fitting & adjustment of an appliance fabricated by an outside lab (submitted with lab fee box 20). These codes are mutually exclusive. Please explain. Thanks!
Yes, you are correct. This answer was for an office that has a lab in house.
If you are sending the impression to an outside lab you will only utilize CPT 99002, however, if you have a lab in house you will utilize 21089.
Thank you for your correction.
