Mitral Valve-in-Valve replacement

Date: Dec 27, 2022

Question:

A previous question in 2018 (ID 11764) asked about mitral valve replacement on an existing prosthetic valve. Your advice was to use either 0483T or 0484T depending on approach. Do you still recommend these codes? Some vendors and insurance carriers are now recommending unlisted code 33999. We cannot find any official coding updates that state 33999 is the correct code to be assigned.
