Part 5 | CPT Breast Education | Breast Reconstruction Using Autologous Tissue Flaps

This is Part 5 of a 6-part series focusing on CPT coding of breast procedures. There are many different types of breast procedures, each having potential stumbling-blocks for coders. This series will address several of the more confusing topics. Part 5 focuses on the coding of different types of autologous tissue breast reconstruction procedures.

 

There are two ways reconstruction with a tissue flap may be done: pedicle or free flap.

Pedicled flap – The flap remains attached at one end to its blood vessels and the rest of the flap is tunneled beneath the skin to the chest site.

Examples:  TRAM (Transverse rectus abdominis muscle – abdomen); Latissimus dorsi (back)

Free flap – The flap is completely detached from the body along with its blood vessels and reattached by microsurgery in the position of the reconstructed breast

Examples:  TRAM (Transverse rectus abdominis muscle – abdomen); DIEP (Deep inferior epigastric perforator- abdomen); SIEA (Superficial inferior epigastric artery – abdomen); Gluteal (buttock)

In CPT there are five different codes that may be assigned for a breast reconstruction using an autologous flap.  Free flaps are all grouped under 19364, regardless of the specific type of flap.

 


 

19364

Breast reconstruction with free flap

 


 

Pedicled autologous flaps are specific for the type of flap – either TRAM or latissimus dorsi.

 


 

19361

Breast reconstruction with latissimus dorsi flap, without prosthetic implant

19367

Breast reconstruction with transverse rectus abdominis myocutaneous flap (TRAM), single pedicle, including closure of donor site;

19368

with microvascular anastomosis (supercharging)

19369

Breast reconstruction with transverse rectus abdominis myocutaneous flap (TRAM), double pedicle, including closure of donor site

 


 

All the flap reconstruction codes include:

  • Elevation and transfer of the flap
  • Muscle dissection
  • Closure of the donor site
  • Breast contouring
