ICD-10-PCS Code For Gallbladder: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0FM4 includes procedures performed to reattach the gallbladder in the hepatobiliary system and pancreas. These ICD-10-PCS codes are used for inpatient documentation when a previously separated gallbladder is placed back in or on to its normal location or another suitable site. Accurate coding within the ICD-10-PCS 0FM4 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Gallbladder Reattachment Procedure Overview

This procedure group covers reattachment procedures involving the gallbladder within the hepatobiliary system and pancreas. Procedures involve putting a separated gallbladder back in or on to its normal or a suitable location. Accurate ICD-10-PCS coding matters for inpatient reimbursement because codes document the specific reattachment performed and support appropriate case mix and payment.

Typical Clinical Scenarios

An adult patient is brought to the emergency department after blunt abdominal trauma with radiographic evidence of gallbladder detachment from its hepatic bed and persistent bile leak. The patient is hemodynamically stable but requires inpatient surgical management to reestablish the gallbladder to its anatomic position to control bile leakage and preserve biliary continuity. An open surgical reattachment is chosen due to associated abdominal injuries and need for abdominal exploration. Typical codes: 0FM40ZZ
A middle-aged patient with a prior hepatic surgery presents electively for planned reattachment after a previously separated gallbladder was preserved in situ during an earlier operation. There is no active infection or hemodynamic instability; the procedure is scheduled in an inpatient setting to restore normal biliary anatomy and function. A minimally invasive percutaneous endoscopic approach is attempted to reapproximate and secure the gallbladder to its normal location. Typical codes: 0FM44ZZ
A patient previously managed nonoperatively for partial avulsion of the gallbladder now presents with recurrent biliary colic and imaging showing malpositioned but viable gallbladder causing intermittent obstruction. Inpatient reattachment is performed to correct the malposition and prevent ongoing symptoms and complications. Because visualization and instrument access can be achieved endoscopically through a percutaneous route, a percutaneous endoscopic reattachment is performed. Typical codes: 0FM44ZZ
