ICD-10-PCS Code For Parotid Duct: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0CTB includes procedures performed to remove all of a specified body part in the mouth and throat. These ICD-10-PCS codes are used for inpatient documentation when a resection of the parotid duct is performed via an open approach. Accurate coding within the ICD-10-PCS 0CTB group is essential for proper inpatient reimbursement, as it captures the specific procedure performed and supports clinical documentation accuracy.

Typical Clinical Scenarios

An adult presents to the emergency department with a large, rapidly expanding infected salivary fistula and uncontrolled purulent drainage from the right preauricular region following prior sialolithiasis; systemic signs of sepsis and failed conservative management prompt inpatient admission for source control. Because the entire right parotid duct is diseased and nonfunctional, open surgical resection of the right parotid duct is performed to remove the infected tract and control ongoing sepsis. Typical codes: 0CTB0ZZ
A middle-aged patient with recurrent obstructive sialadenitis of the right parotid duct causing chronic pain, recurrent swelling, and multiple unsuccessful endoscopic stone extractions is scheduled for an elective inpatient procedure for definitive management. The planned inpatient operation involves open resection of the right parotid duct to eliminate the recurrent obstruction and prevent further episodes. Typical codes: 0CTB0ZZ
A patient who previously underwent partial duct surgery presents with persistent ductal stricture and recurrent mucocele formation on the right side, resulting in progressive dysfunction and recurrent admissions for intravenous antibiotics and drainage. Surgical management requires open resection of the entire right parotid duct to remove the damaged ductal segment and resolve the chronic complication. Typical codes: 0CTB0ZZ
