Testicular dysfunction (E29) ICD-10-CM
The E29 code range covers testicular dysfunction with 5 ICD-10-CM diagnosis codes. 4 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
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.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the E29 range.
Eunuchism
The state of being a eunuch, a male without TESTES or whose testes failed to develop. It is characterized by the lack of mature male GERM CELLS and TESTICULAR HORMONES.
Hypogonadism
Condition resulting from deficient gonadal functions, such as GAMETOGENESIS and the production of GONADAL STEROID HORMONES. It is characterized by delay in GROWTH, germ cell maturation, and development of secondary sex characteristics. Hypogonadism can be due to a deficiency of GONADOTROPINS (hypogonadotropic hypogonadism) or due to primary gonadal failure (hypergonadotropic hypogonadism).
Kallmann Syndrome
A genetically heterogeneous disorder caused by hypothalamic GNRH deficiency and OLFACTORY NERVE defects. It is characterized by congenital HYPOGONADOTROPIC HYPOGONADISM and ANOSMIA, possibly with additional midline defects. It can be transmitted as an X-linked (GENETIC DISEASES, X-LINKED), an autosomal dominant, or an autosomal recessive trait.
Prune Belly Syndrome
A syndrome characterized by abdominal wall musculature deficiency, cryptorchism, and urinary tract abnormalities. The syndrome derives its name from its characteristic distended abdomen with wrinkled skin.
Spinocerebellar Degenerations
A heterogenous group of degenerative syndromes marked by progressive cerebellar dysfunction either in isolation or combined with other neurologic manifestations. Sporadic and inherited subtypes occur. Inheritance patterns include autosomal dominant, autosomal recessive, and X-linked.
About the E29 Code Range
ICD-10 codes under E29 are used specifically to classify various forms of testicular dysfunction, which affect testicular hormone production or function. These codes guide the diagnosis and treatment documentation of conditions related to abnormal testicular activity.
The ICD-10 code for testicular dysfunction (E29) includes distinct subcategories. For example, E29.0 covers testicular hyperfunction, also known as hypergonadism, which involves excessive testicular hormone activity. In contrast, E29.1 addresses testicular hypofunction, with numerous synonyms listed like primary hypogonadism, male hypogonadism, or acquired testicular failure, reflecting reduced hormone production or testicular failure. Other forms, such as E29.8, capture other testicular dysfunctions including Mullerian inhibiting factor deficiency. When specific details are unavailable, E29.9 is used for unspecified testicular dysfunction, covering broad conditions like disorder of testicular differentiation or anemia of gonadal dysfunction.
These codes help medical coders and healthcare professionals accurately document and differentiate between various testicular conditions, ensuring precise communication and appropriate care.
