Infected hydrocele

This code signifies a hydrocele that has become infected. A hydrocele is a collection of serous fluid in a body cavity, most commonly within the tunica vaginalis of the testis or along the spermatic cord, and in this case, it is complicated by an infection.

Use this code when documentation clearly indicates an existing hydrocele with signs and symptoms of infection, such as erythema, warmth, tenderness, or purulent discharge from the scrotal area, or systemic signs of infection like fever. This code is appropriate when the infection is directly associated with the hydrocele.

• Ensure documentation specifies both the presence of a hydrocele and an active infection.
• Do not confuse with an uncomplicated hydrocele (N43.3) or other inflammatory conditions of the male genital organs without a pre-existing hydrocele.
• Code any associated systemic infection or specific infectious agent (e.g., bacterial, fungal) as an additional diagnosis, if identified and documented.
