Good morning Fellow Coders,

Question about Closure with adjacent tissue transfer of myofascial gluteus flaps, 110 square cms x 2 sides 220 sq cms total would cpt code would cpt 15734 be appropriate see op note below.

The patient was found have a large pilonidal cyst with multiple sinus openings.
The cyst extended down to the presacral fascia in the midline.

The patient was brought to the operating room, and after the induction of
general anesthesia, was placed in the prone jack-knife position upon the
operating table. Each of the sinus openings was probed with a blunt malleable
probe. The cyst openings were then injected with 50% dilute methylene blue dye
to help identify the cyst wall intraoperatively. The skin was infiltrated with 0.5% Marcaine with epinephrine to aid in post-operative analgesia.
A longitudinal elliptical incision was made in the midline encompassing all of
the sinus openings. Bovie electrocautery was used to carry the incision
full-thickness through the skin and subcutaneous tissues, excising the cyst in
its entirety. The dissection was carried down to the presacral fascia where the
cyst was is seen to extend. The cyst was excised in its entirety en bloc with its overlying ellipse of skin. It was passed off the table as specimen. Hemostasis was obtained using Bovie electrocautery. The wound was irrigated with sterile saline and then dried.
At this time, we detached both the right and left gluteus muscles from their
insertion on the sacrum using Bovie electrocautery. The myofascial flaps were
raised approximately 5 cm laterally for each flap. This included development of the flaps by dividing tissue deep to and superficial to the muscle. The midline defect, which
consisted of only presacral fascia and the midline sacrum in the middle was
approximately 11 x 10 cms. We used these muscle flap to cover this area by
suturing the 2 advanced myofascial flaps to one another using a running 0
Vicryl suture in the midline. Once these were sutured
together, the presacral fascia and sacral bone were completely covered with the
myofascial flaps in the midline, allowing for better blood supply for healing of
the large wound and decreased depth of the gluteal cleft.
The wound was again irrigated with sterile saline and then dried. Hemostasis
was excellent. A 10 flat JP drain was placed in the subcutaneous space and run out through a separate stab incision in the left buttock.
The drain was sutured to the skin with a 3-0 Nylon stitch. The subcutaneous tissue was reapproximated using 2-0 Vicryl in a
running stitch. The skin was closed using 4-0 Monocryl in a running
subcuticular stitch. Mastisol, Steri-Strips, and then a sterile dressing were
applied. All sponge, needle, and instrument counts were correct at the end the
case. The patient tolerated the procedure well, was extubated, and brought to
the recovery room, awake and in stable condition.

Hi, I agree with your code 15734 for the gluteus muscle flap. Because the physician states that he creates two separate flaps (one on the left and one on the right) and then advances them and brings them together to close the defect, you can actually code 15734, 15734.59 (to give credit for both flaps).
