Open wound of pharynx, without mention of complication

This code signifies an acute, unhealed break in the skin or mucous membrane of the pharynx, resulting from trauma. It indicates that the wound is open to the external environment and has not yet developed complications such as infection or delayed healing.

Apply this code for traumatic injuries to the pharynx documented as an open wound, laceration, or puncture, without any mention of infection, foreign body, or other complications. Documentation should clearly specify the pharynx as the anatomical site of the open wound.

• Differentiate from superficial injuries like abrasions or contusions of the pharynx.
• Do not use if documentation indicates infection, foreign body, or delayed healing; instead, code to a more specific complication.
• Always sequence as a primary diagnosis if it is the reason for the encounter.
