New access nephrostomy after failed exchange

Date: Jul 25, 2022

Question:

A patient has an existing nephrostomy tube. Contrast is injected, which confirms that the nephrostomy tube is malpositioned. The tube is removed. The physician attempts to place a new nephrostomy tube via the existing access but is unsuccessful. He then places the new nephrostomy tube via a new access. Would this be coded as 50435 for an exchange? Or would it be 50432 since it is via a new access?
