CPT code for stenting of the RV-PA homograft conduit
Question:
Our providers are stenting stenotic areas of the RV-PA conduit in patients with TOF repairs. Here is a snip of what is being done: The conduit is balloon dilated with a 12 mm Atlas (18 atms), 14 mm Atlas (18 atms), and 16 mm Atlas (18 atms) with simultaneous RCA angiography.
"A 10 mm x 40 mm Palmaz XL transhepatic biliary stent is placed across the conduit on a 16 mm BIB. Post-stenting, RVOT angiography shows an unobstructed distal stent with proximal narrowing at the previously placed stent. The stented conduit measures 14 mm distally and 11.8 mm at the proximal conduit where the previous stents were placed."
What would be the appropriate code in these cases, 33745 or 37236? Or another code altogether?
