Hydrocele and spermatocele (N43)

The ICD-10 code section N43 is used specifically for classifying different types of hydrocele and spermatocele, two conditions affecting the male genital area. These codes help identify precise diagnoses such as encysted hydrocele, infected hydrocele, and various forms of spermatocele.

Hydrocele and spermatocele (N43) cover conditions like the encysted hydrocele (N43.0), also known as hydrocele of the spermatic cord, and the infected hydrocele (N43.1), which refers to inflammation in the hydrocele of the testis or tunica vaginalis. Other hydrocele (N43.2) accounts for less common variations, while hydrocele, unspecified (N43.3) includes acquired or post-traumatic hydroceles and hydroceles involving the tunica vaginalis. For cystic masses in the epididymis, spermatocele of epididymis is coded under N43.4, with subcategories specifying unspecified (N43.40), single (N43.41), or multiple (N43.42) spermatoceles. These detailed codes assist coders and healthcare providers in selecting precise diagnoses, supporting accurate medical documentation and communication. Using the ICD-10 code for hydrocele and spermatocele allows clear identification of these male genital conditions, including synonyms like cyst of epididymis and adult hydrocele.

Instructional Notations

Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

  • hydrocele of spermatic cord, testis or tunica vaginalis

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • congenital hydrocele P83.5

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Spermatocele

A cystic dilation of the EPIDIDYMIS, usually in the head portion (caput epididymis). The cyst fluid contains dead SPERMATOZOA and can be easily differentiated from TESTICULAR HYDROCELE and other testicular lesions.
