Male infertility (N46) ICD-10-CM
The N46 code range covers male infertility with 21 ICD-10-CM diagnosis codes. 16 of them are billable and valid for claim submission in fiscal year 2027, 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 N46 range.
Azoospermia
A condition of having no sperm present in the ejaculate (SEMEN).
Infertility, Male
The inability of the male to effect FERTILIZATION of an OVUM after a specified period of unprotected intercourse. Male sterility is permanent infertility.
Oligospermia
A condition of suboptimal concentration of SPERMATOZOA in the ejaculated SEMEN to ensure successful FERTILIZATION of an OVUM. In humans, oligospermia is defined as a sperm count below 20 million per milliliter semen.
About the N46 Code Range
Male infertility means a man cannot fertilize an egg after a specified period of unprotected intercourse. N46 sits among diseases of the male genital organs.
The category has separate branches for azoospermia (N46.0) and oligospermia (N46.1), both forms of male infertility. Each branch distinguishes organic cases from those attributed to causes outside the testes. Those outside causes divide further into drug therapy, infection, blocked efferent ducts, radiation, systemic disease, and other causes. Separate codes identify other male infertility (N46.8) and unspecified male infertility (N46.9).
