Congenital hydrocele

This code signifies the presence of a congenital fluid collection within the tunica vaginalis of the testis or along the spermatic cord. This condition results from the failure of the processus vaginalis to close completely, allowing peritoneal fluid to accumulate. It is typically observed at birth or shortly thereafter.

Use this code for newborns or infants diagnosed with a hydrocele that is present at birth or clearly identified as congenital in origin. Documentation should explicitly state "congenital hydrocele" or describe a hydrocele identified in the neonatal period without an acquired cause.

• Differentiate from acquired hydroceles, which have different ICD-10-CM codes.
• Ensure documentation specifies laterality (e.g., right, left, bilateral) if known, though P83.5 does not differentiate.
• Do not use this code for hydroceles that develop later in life due to trauma, infection, or other acquired causes.
