Call On Mod 52, 53 for Rescue in Incomplete ERCP Procedures

Question: I’m coding an ERCP, and the doctor made numerous attempts with the catheter tip and with the guidewire -- but these failed. Then he used the standard Hydratome, but over the course of an hour, the physician did not perform a single direct cannulation of either the common bile duct or pancreatic duct, nor did he insert the wire or contrast. What modifier should I use for this?

Answer: During an ERCP (endoscopic retrograde cholangiopancreatography), visualization of the bile ducts and the pancreatic ducts is an integral part of the standard procedure. If your gastroenterologist runs into problems visualizing any of the ducts (bile and pancreatic), he has performed an incomplete procedure.

You should report the session with CPT® code 43260 (Endoscopic retrograde cholangiopancreatography (ERCP); diagnostic, including collection of specimen[s] by brushing or washing, when performed [separate procedure]) and append the code with an appropriate modifier.

You have two modifiers that you could attach to the ERCP code to indicate an incomplete procedure: modifier 52 (Reduced services) or modifier 53 (Discontinued procedure).

Commercial payers that strictly follow CPT® coding principles will most likely require modifier 52. CPT® states that you should use this modifier when “under certain circumstances a service or the procedure is partially reduced or eliminated at the physician’s discretion.”

Because the CPT® definition for modifier 53 states that you should use it when extenuating circumstances threaten the patient’s well-being, you may need to indicate that the physician started the ERCP but discontinued it. Some Medicare carriers may accept this method.

The catch: Some carriers may require modifier 53 as they do for an incomplete colonoscopy. The only way to know for sure is to check with your carrier.

  • Because the visualization of the ducts is the purpose of the ERCP procedure, however, you should be prepared to receive no reimbursement or a significantly reduced payment for a procedure when your physician merely attempted but did not achieve the full procedure -- no matter how long the attempted procedure lasted.
