Encysted hydrocele

This code represents an abnormal collection of serous fluid within the tunica vaginalis of the testis or spermatic cord, which is enclosed within a sac or cyst. This fluid accumulation is typically localized and distinct, differentiating it from a more generalized hydrocele.

Apply this code when documentation explicitly states "encysted hydrocele" of the testis or spermatic cord. This diagnosis is often made during physical examination or imaging studies (e.g., ultrasound) revealing a well-defined, fluid-filled mass.

• Differentiate from other types of hydroceles (e.g., congenital, infected) which have distinct codes.
• Ensure documentation specifies "encysted" to support this specific code rather than a general hydrocele.
• Consider laterality if specified in the clinical notes, although this particular code does not differentiate laterality.
