Removal of Eschar

Question:

My plastic surgery saw a patient who sustained an approximately 40% total body surface area burn in a fire. He has previously undergone excision and allograft placement of his extremities. He now came back for removal of the eschar that remains present on his torso and bilateral thighs. The total area excised was 5275 sq cm. How would I code this?

Answer:

You will report CPT code 15002 (surgical preparation) for the first 100 sq cm and 15003 for each additional 100 sq cm. CPT code 15003 is reported with 52 units.
