Patient EducationClinical

Testicular Disorders

Testicles, or testes, make male hormones and sperm. They are two egg-shaped organs inside the scrotum, the loose sac of skin behind the penis. It's easy to injure your testicles because they are not protected by bones or muscles. Men and boys should wear athletic supporters when they play sports.

Questions About N43Overview

What is the ICD-10 code for hydrocele and spermatocele?

N43 is the ICD-10-CM category for hydrocele and spermatocele, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is N43 (Hydrocele and spermatocele) a billable code?

No. This is a category header that groups the codes for hydrocele and spermatocele, and headers cannot be submitted on claims. Claims for hydrocele and spermatocele need a more specific code from this category, such as N43.0, N43.1, and N43.2.

Can N43 be reported with P83.5?

Not as a rule. The Excludes1 note on N43 lists "congenital hydrocele (P83.5)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
