Typical Clinical Scenarios

An adult patient presents urgently with acute mastoiditis complicated by extension of infection into the right middle ear with necrotic tissue and persistent purulence despite IV antibiotics. The otologic surgeon performs an open surgical resection to remove all infected middle ear mucosa and involved tissue to control the infection and prevent intracranial spread. This inpatient procedure is recorded because the entire targeted right middle ear tissue is removed without placement of any prosthesis or graft. Typical codes: 09T50ZZ
A middle-aged patient with chronic, refractory otitis media and cholesteatoma of the right middle ear is electively admitted for definitive surgical management after failed medical therapy and hearing deterioration. The planned operation is complete resection of the diseased right middle ear structures via endoscopic transcanal access to eradicate the cholesteatoma while avoiding an external incision. The procedure removes all targeted middle ear tissue without implantation of a replacement device. Typical codes: 09T58ZZ
A patient who previously underwent partial middle ear debridement develops recurrent symptomatic disease with persistent drainage and granulation tissue in the right middle ear, necessitating a more extensive inpatient procedure to remove all remaining diseased middle ear tissue. Because prior surgery altered anatomy and prior conservative measures failed, the surgeon performs an open resection to excise the residual pathologic right middle ear tissue completely, without inserting any replacement materials. This is documented as a resection of the right middle ear during a revision setting. Typical codes: 09T50ZZ
