Auditory Ossicle, Left Resection Procedure Overview

This procedure group includes inpatient resections of the left auditory ossicle, targeting the ossicular chain within the ear, nose, sinus body system. Procedures involve surgically cutting out all of the specified auditory ossicle on the left side without replacement to remove diseased, damaged, or nonfunctional ossicular tissue. Accurate ICD-10-PCS coding ensures the inpatient record reflects the extent of resection and supports appropriate case mix grouping and reimbursement.

Typical Clinical Scenarios

An adult patient is admitted urgently with chronic, destructive cholesteatoma of the left middle ear causing erosion and nonviable ossicular chain elements with persistent conductive hearing loss and recurrent otorrhea despite prior medical therapy. Inpatient resection is performed to remove the entire left auditory ossicle that is diseased and nonfunctional, with no prosthesis placed during the same admission to control infection and prevent further complications. The goal is complete removal of the affected ossicle to eradicate disease and allow for staged reconstruction later if indicated. Typical codes: 09TA0ZZ
A patient with long-standing severe otosclerosis of the left ear and progressive conductive hearing loss elects to undergo staged surgical management. During the planned inpatient procedure, the nonfunctional left auditory ossicle is totally removed via an open surgical approach without insertion of a prosthesis to prepare the middle ear for future reconstruction. The procedure is elective and performed to eliminate the pathologic ossicle as part of a planned multi-stage treatment strategy. Typical codes: 09TA0ZZ
A patient returns to the hospital with persistent pain and chronic drainage after prior middle ear surgery; intraoperative findings show infected, necrotic residual ossicular tissue on the left side. To control ongoing infection and remove the source of inflammation, the entire left auditory ossicle is resected endoscopically via a natural orifice approach without replacement during the same admission. This revision procedure aims to eradicate infected tissue and optimize conditions for later definitive reconstruction. Typical codes: 09TA8ZZ
