Component Seperation

Question:

Our provider has documented abdominal closure by component separation, is there a separate CPT code for this closure or is it included in the main procedure?

Answer:

Component separation, sometimes referred to as a rectus advancement flap, refers to a myocutaneous flap of the trunk (a flap of subcutaneous tissue, fascia and muscle with an intact vascular supply) represented by CPT code 15734. To report this code the providers documentation must demonstrate that the oblique, transversalis or transverse abdominus and rectus abdominus muscles have been incised and mobilized toward the midline with an intact vascular supply. This code can be reported only once for each side and bilateral modifier does not apply, so when performed bilaterally report as 15734, 15734-59.​
