Code Description

ICD-10 S31.4 is a billable code used to indicate a diagnosis of open wound of vagina and vulva.

Key Diagnostic Point:

An open wound of the vagina and vulva refers to a traumatic injury that results in a break in the skin or mucous membrane of the female genitalia. This type of injury can occur due to various mechanisms, including blunt or penetrating trauma, surgical procedures, or childbirth. The clinical presentation may include lacerations, abrasions, or puncture wounds, which can lead to significant bleeding, pain, and risk of infection. In cases of severe trauma, associated injuries may involve the pelvic organs, such as the bladder or rectum, necessitating a thorough evaluation for concurrent genitourinary injuries. Emergency surgical intervention may be required to control bleeding, repair the wound, and prevent complications. The management of these injuries often involves a multidisciplinary approach, including trauma surgeons, gynecologists, and urologists, particularly in cases of complex pelvic injuries or when there is a risk of significant organ damage.
