External constriction of right ear, subsequent encounter

This code describes an injury to the right ear caused by external compression or constriction, such as from a tight headband, earplug, or other object. It indicates that the patient is in the healing phase of this injury, receiving follow-up care after the initial treatment.

Use this code for subsequent encounters when a patient presents for ongoing management, wound care, or evaluation of a previously diagnosed external constriction of the right ear. Documentation should clearly state the laterality (right ear) and the nature of the constriction, along with the "subsequent encounter" status.

• Ensure documentation specifies "right ear" and that the encounter is not the initial treatment for the injury.
• Distinguish from initial encounters (S00.441A) or sequela (S00.441S) of the same injury.
• Code any associated complications (e.g., infection, necrosis) separately.
