A patient presents to the office with a visible lesion or abnormality on the external ear. The provider, typically an otolaryngologist, dermatologist, or family medicine physician, evaluates the area and determines that a biopsy is necessary to rule out benign or malignant neoplasms, or to further investigate persistent symptoms such as chronic otitis externa or unexplained masses. The procedure is performed in the office setting (Place of Service 11), where a small tissue sample is taken from the external ear for pathological examination. The workflow includes pre-procedure assessment, local anesthesia, biopsy, specimen handling, and post-procedure instructions.
