50432 vs. 50435 for dislodged Nephrostomy caths

Date: Feb 26, 2018

Question:

We occasionally have patients who have had nephrostomy catheters placed. The catheter becomes dislodged at home, and they return to have it replaced. Upon arrival, there isn't a catheter present. The nephrostomy tract is still open, and a catheter is easily reinserted. Do you consider this a nephrostomy placement (50432) or an exchange (50435)?
