Typical Clinical Scenarios

An adult presents to the emergency department with acute, painful right external ear canal obstruction after inserting a foreign body (bead) deep in the canal; failed bedside removal and persistent pain with risk of canal trauma lead to inpatient operative removal under direct visualization. A surgical extirpation is performed to remove the solid foreign matter from the right external ear canal using an open approach when bedside techniques are unsafe. Typical codes: 09C00ZZ
An elderly inpatient with severe cerumen impaction on the right side causing conductive hearing loss and persistent dizziness after conservative outpatient attempts undergoes a planned operative procedure in the hospital to remove hardened cerumen under visualization and irrigation; the procedure is done percutaneously without endoscopic equipment. Typical codes: 09C03ZZ
A patient hospitalized for multiple facial fractures has retained particulate debris and granulation tissue within the right external ear after prior trauma; the otologic team performs a percutaneous endoscopic extirpation to debride and remove solid matter from the right external ear to reduce infection risk and promote healing. Typical codes: 09C04ZZ
