Occlusion of the fistula glue

[Shirleybala]

Can I use 46706 for this occlusion with glue

History: Persistent fistulous communication between pelvic
collection and bowel, status post drainage of a pelvic collection

Procedure: Patient was appropriately consented and placed supine
on angiographic table. Contrast was injected into the inside the
drainage catheter. Again, the study demonstrated small amount of
collection in the pelvis communicating with the bowel. The in situ
drainage catheter was replaced with a 7-French sheath over a stiff
wire. Using a combination of a 4-French Bernstein catheter and a
Glidewire access was gained into the bowel through the fistulous
communication. Position of the catheter was confirmed by
injection of contrast. 100 cc of Fibrin glue was then injected as
the catheter was withdrawn through the fistulous channel under
fluoroscopic guidance. The sheath was removed

Conclusion: Occlusion of the fistulous communication between the
pelvic collection and bowel with fibrin glue. Draining catheter
was removed.

I see 76080/49424 for the initial injection through the existing tube. As for the glue, I'm leaning towards an unlisted code. 46706 is for an anal fistula, this sounds more like a pelvic/bowel fistula.
