Code Description

ICD-10 S31.20 is a billable code used to indicate a diagnosis of unspecified open wound of penis.

Key Diagnostic Point:

An unspecified open wound of the penis refers to a traumatic injury that results in a break in the skin or mucous membrane of the penile structure. This type of injury can occur due to various mechanisms, including blunt trauma, lacerations, or penetrating injuries. The clinical presentation may vary from minor abrasions to severe lacerations that could involve deeper structures such as the corpus cavernosum or urethra. The management of such injuries often requires a thorough assessment to rule out associated injuries, particularly in cases of pelvic trauma, where injuries to the genitourinary system may coexist. Emergency surgical intervention may be necessary to repair significant lacerations, control bleeding, or address any potential complications such as infection or urethral injury. Proper documentation of the mechanism of injury, extent of the wound, and any associated injuries is crucial for accurate coding and treatment planning.
