Acquired deformity of pinna, right ear

This code signifies a non-congenital malformation or distortion of the external ear's cartilaginous structure on the right side. This deformity can result from various causes, including trauma, infection, or inflammatory processes, leading to an altered shape of the auricle.

Use this code when documentation specifies an acquired, rather than congenital, deformity affecting the right pinna. This is appropriate for conditions like cauliflower ear (perichondrial hematoma), keloids, or other structural changes to the external ear resulting from injury or disease. Ensure the medical record clearly identifies the laterality as the right ear.

• Always confirm laterality (right, left, or bilateral) from the physician's documentation.
• Distinguish between acquired deformities and congenital malformations (Q17.x series).
• Consider an external cause code (V00-Y99) if the deformity is due to a specific injury or trauma.
