Oligospermia due to systemic disease

This code represents a reduced sperm count (oligospermia) that is a direct consequence of an underlying systemic medical condition affecting the entire body, rather than a localized testicular issue. This systemic disease impairs spermatogenesis, leading to insufficient sperm production.

Use this code when documentation clearly links oligospermia to a systemic disease, such as chronic kidney disease, diabetes mellitus, or certain autoimmune disorders. The physician's notes should explicitly state the systemic disease as the etiology for the low sperm count.

• Always code the underlying systemic disease first, followed by this code as a secondary diagnosis.
• Ensure the documentation specifies "due to systemic disease" to differentiate from other causes of oligospermia.
• Do not use this code for oligospermia of unknown origin or due to localized testicular issues; instead, consider N46.11 or N46.19.
