Cauliflower ear, unspecified ear

This code represents a deformity of the external ear characterized by thickening and scarring of the cartilage, giving it a lumpy or cauliflower-like appearance. It typically results from repeated trauma or hematoma to the auricle, often seen in contact sports. This specific code is used when the affected ear (left, right, or bilateral) is not specified in the documentation.

Use this code when documentation clearly indicates a diagnosis of cauliflower ear without specifying laterality. This often occurs in initial diagnostic encounters or when the physician simply states "cauliflower ear" without further detail. Supporting documentation includes physician notes describing the characteristic ear deformity.

• Do not use this code if the documentation specifies laterality (e.g., "cauliflower ear, left ear"). In such cases, a more specific code should be selected.
• Distinguish from other ear deformities like microtia or macrotia, which have different etiologies and appearances.
• Ensure the documentation supports a current diagnosis of cauliflower ear, not just a history of ear trauma.
