A cut through the skin and cartilage is made on the medial side of the tragus, leaving 2 mm of cartilage in the dome of the tragus for cosmesis. The tragal cartilage is harvested together with the perichondrium.
Can CPT 21235 be billed with CPT 69631?
If a physician uses a separate incision for a graft during tympanoplasty, the coder should bill for the tympanoplasty (CPT 69631) code and for the corresponding graft code, such as a tissue graft (CPT 20926) or a cartilage graft (CPT 21235).
What are the types of skin grafts?
