Pilonidal Disease Excision

Question:

I frequently perform adjacent tissue transfers (CPT 14000, 14001, 14020). When I excise pilonidal disease (CPT 11770, 11771, 11772) and then perform an adjacent tissue transfer, can I report both the excision and the tissue transfer codes, or is only the tissue transfer separately billable?

Additionally, in cases where I excise a malignant lesion (CPT 11604, 11606) and close the defect with an adjacent tissue transfer, my understanding is that only the adjacent tissue transfer code (e.g., 14000) is reportable, and the excision is considered included. Is this correct?

Answer:

This is a great question. Even though pilonidal excision is a “disease excision” rather than a lesion excision, CPT still treats the excision as included in the ATT. If you excise pilonidal disease and close with an adjacent tissue transfer (e.g., Limberg flap, Karydakis flap, Z-plasty), you bill only the ATT code (14000–14001–14020 etc.). Keep in mind when you perform an adjacent tissue transfer to close a defect, you do NOT separately bill the excision of a lesion (benign or malignant).

The ATT includes:

• Creating the defect (whether by trauma or excision)

• Preparing the wound bed

• Closing the defect with the flap

The excision is considered included in the ATT code.

This applies to:

• Benign lesion excision (11400 series)

• Malignant lesion excision (11600 series)

• Benign cyst excision (e.g., pilonidal disease 11770–11772)

• Scar revision excision

• Any excision that results in the defect you are closing with ATT
