Question: The podiatrist treated mallet toe with an open flexor tenotomy at the plantar aspect of the proximal interphalangeal joint (PIPJ). Which procedure code should we report? Tennessee Subscriber Answer: Since the podiatrist addressed one tendon and one toe, you should report 28232 (Tenotomy, open, tendon flexor; toe, single tendon (separate procedure)). Caution: There are several tenotomy codes to choose from, so make sure you pick the correct one. You would report 28232 for an open procedure, but if it was percutaneous, you could look to a code like 28010 (Tenotomy, percutaneous, toe; single tendon). Also, 28232 involves a tendon in the toe, not the foot like 28230 (Tenotomy, open, tendon flexor; foot, single or multiple tendon(s) (separate procedure)). Mallet toe definition: Mallet toe is a supple or fixed contracture (curling) of the DIPJ (end joint) of a lessertoe.
