Typical Clinical Scenarios

A middle-aged patient presents after a motor vehicle collision with bilateral traumatic avulsion of the external ears with extensive soft tissue loss and exposed cartilage; the injuries require inpatient surgical reconstruction using the patients own tissue to recreate the auricular structure and restore form, performed via open operative techniques to secure grafts and flaps. Typical codes: 09R207Z
An older adult with bilateral congenital microtia undergoing a planned, staged inpatient surgical reconstruction where prosthetic (synthetic) auricular implants are placed to replace the absent external ears; the operation is elective and completed via an open approach to seat and secure the prosthetic constructs. Typical codes: 09R20JZ
A patient with prior ear reconstruction who develops recurrent infection and failure of a previous biologic graft bilaterally, necessitating inpatient removal of failed tissue and replacement with nonautologous (allogeneic) tissue substitute using an open approach to control infection and reestablish external ear integrity. Typical codes: 09R20KZ
