Ulcer

​​​​​​​“I have a Medicare patient that has healed a neuropathic ulcer (L97.522, E11.62) at the plantar base of his 5th metatarsal. He needs paring of the hyperkeratotic tissue, frequently with hemorrhagic changes, every four weeks or he re-ulcerates at this location. Should this be coded as: CPT 11055 using a GY modifier every other visit? Debriding devitalized tissue CPT 97597 or am I evaluating and managing an ulcer CPT 9921X?”

“How would you code this? I’m stumped. Operation 1. Attention was directed to the medial aspect of left great toe where an incision was made overlying the interphalangeal joint. The incision measured about 3-4 cm in length, the incision was deepened via sharp and blunt dissection, careful attention paid to all neurovascular structures appropriately retracted as necessary. The incision was carried down to bone, the soft tissue was freed from the medial side of the bone at the IPJ. The long flexor tendon was reflected plantarly. The accessory bone was found on the left and seemed to be adherent to the phalanx. It was removed and sent to pathology. The wound was flushed. C-arm radiograph taken pre and post to be sure that the bone had been removed. It was. The flexor tendon was reapproximated and maintained using 2-0 Vicryl, skin closure with 2-0 Vicryl. 4-0 Prolene. Operation 2. Same, right foot Operation 3. Attention was directed to the ulcer of the left great toe, 2 converging semielliptical incisions made surrounding the ulcer, excised and sent to pathology. There was necrotic tissue and debris within it. This was sent as well. The wound was flushed and closure performed using 2-0 Vicryl, 4-0 Prolene. Operation 4. Same, right great toe The doctor coded it as follows: CPT 28315-50, CPT 11422-TA, CPT 11422-T5.”

“I have a patient that has bilateral ulcers with same depth on both feet, and I billed CPT 11042 -RT and CPT 11042 -LT, -59. Insurance has denied the second procedure as a duplicate. How else does this need to be billed as far bilateral ulcer procedures?”

“Can one appropriately bill a debridement code, such as CPT 11042, each time when applying a skin substitute if indicated in a hospital, outpatient wound care clinic?”

“What code would you recommend for the excision of a pressure ulcer? Here is an excerpt from the operative report: “Attention was directed to the left plantar medical foot at the level of the arch where an approximately 3 cm round chronic ulceration with underlying bursa formation was noted. At this time, an elliptical incision was made in a 3:1 fashion running in line with the foot from toe to heel. This incision was deepened through subcutaneous tissues with care being taken to identify and retract all vital neurovascular structures. At this time, dissection scissors were utilized in order to remove the chronic ulceration with underlying bursa. The skin margins were then separated in order to free up and allow for skin closure.”
