External constriction of left ear, subsequent encounter

This code describes an injury to the left ear caused by an external force that restricts blood flow or compresses the tissue. This typically results from tight headwear, jewelry, or other objects that encircle or press against the ear. The "subsequent encounter" designation indicates that the patient is receiving follow-up care for this previously diagnosed injury.

Use this code when a patient presents for ongoing treatment, monitoring, or healing of an external constriction injury to their left ear. Documentation should clearly state the laterality (left ear), the nature of the injury as an external constriction, and indicate that this is not the initial visit for this specific condition. Examples include wound care, infection management, or assessment of healing progress after the initial injury.

• Ensure documentation specifies "left ear" to support laterality.
• Verify the encounter type; "D" for subsequent encounter is crucial and distinguishes it from initial (A) or sequela (S) encounters.
• Consider an external cause code (V00-Y99) to describe the circumstances of the injury, if known and documented.
