Hematoma of pinna, unspecified ear

This code signifies a localized collection of blood within the cartilage and perichondrium of the external ear (pinna), where the specific ear affected is not documented. It represents a bruise or contusion of the outer ear that has resulted in a hematoma formation.

Use this code when the medical record clearly indicates a hematoma of the pinna, but the documentation does not specify whether it is the right or left ear. This typically occurs following trauma to the ear, such as a direct blow or friction. Documentation should include the presence of a hematoma on the external ear and a lack of laterality specification.

• Avoid using this code if the laterality (right or left ear) is documented; instead, choose the more specific code.
• Ensure the documentation differentiates a simple contusion from a hematoma, which involves a distinct collection of blood.
• Consider external cause codes (V, W, X, Y categories) to describe the circumstances of the injury, if known.
