Q & A with Dr. Z – WavelinQ System

by David Zielske, MD, CIRCC, COC, CCVTC, CCC, CCS, RCC

Question: WavelinQ System
We have implanted a WavelinQ device but are not sure how to code this procedure. There is a supply C-code available, but we don’t know which CPT code to use.

The WavelinQ is fairly new technology for creating an AV dialysis fistula. It requires separate percutaneous venous and arterial access and uses two catheters with a built in magnet to position the catheters. RF energy is then used to create the fistula.

The C-code you refer to as a supply code is probably the procedure code. The procedure is reported with HCPCS level II code, C9755, with a national APC payment of $9,669.04. This code became effective on 1/1/2019. Payment at an ASC is about half as much as APC payment. For physician billing, there is no specific code. Physicians report unlisted code 37799 for the procedure.

Another new method for AV fistula creation uses the Ellipsys device, which is reported with code C9754.
