Bitten by mouse, initial encounter

This code signifies an injury sustained from a mouse bite, specifically during the initial presentation for care. It indicates direct physical trauma caused by the animal's teeth breaking the skin.

Apply this code when a patient presents to a healthcare facility for the first time following a mouse bite. This includes emergency department visits, urgent care, or initial physician office consultations for evaluation and treatment of the wound.

• Ensure documentation clearly states the injury was caused by a mouse, not another rodent.
• Always append the appropriate seventh character for the encounter type (A for initial, D for subsequent, S for sequela).
• Code any associated infections or other complications separately.
