Hematoma of pinna, bilateral

This code signifies the presence of a localized collection of blood, typically clotted, within the tissue of both external ears (pinnas). It results from trauma causing hemorrhage into the auricular cartilage and perichondrium. This condition can lead to swelling, pain, and potential deformity if not treated.

Apply this code when documentation explicitly states a hematoma affecting both pinnas. This often occurs following direct blunt trauma to both ears, such as from sports injuries or altercations. Supporting documentation should detail the bilateral involvement and the nature of the hematoma.

• Ensure documentation clearly specifies "bilateral" involvement; otherwise, use a unilateral code (H61.121 or H61.122) or unspecified (H61.129).
• Do not confuse with seroma of pinna (H61.11-) or other specified disorders of the external ear.
• Consider an external cause code (V00-Y99) if the cause of the trauma is known and documented.
