N46.02 Azoospermia due to extratesticular causes

ICD-10-CM Diagnosis Code N46.02: Azoospermia due to extratesticular causes

ICD-10-CM code N46.02 represents the diagnosis of azoospermia due to extratesticular causes, classifying this condition as a disease or syndrome. The terminology is active, falling under the broader parent category of general azoospermia. This code distinguishes extratesticular factors from other specified origins like drug therapy or infections. 1 5

Plain-language overview

Code N46.02 identifies a medical diagnosis of azoospermia due to extratesticular causes, and clinical literature describes obstructive azoospermia as an anatomical obstruction of the extratesticular ductal system. 1 2

What this code represents

The official label for N46.02 is azoospermia due to extratesticular causes, and the terminology record classifies this concept with the semantic type of disease or syndrome. 1

N46.02 is a child concept of N46.0, which is the general code for azoospermia, establishing a direct hierarchical relationship within the diagnosis coding system. 1

Coding details

The N46.02 terminology record currently has no narrower child concepts, and the code is distinct from more specific variants like N46.021 for drug therapy or N46.022 for infections. 1 5

Coding manuals list conditions like obstruction of efferent ducts and other extratesticular causes under this diagnosis family, alongside related oligospermia due to extratesticular causes. 3 4

Documentation considerations

Clinical evaluation of azoospermia involves medical history, physical examination, and serum hormone measurements, with obstructive causes often linked to anatomical blockages in the extratesticular ductal system. 2

Distinguishing obstructive azoospermia from non-obstructive testicular failure relies on parameters like follicle-stimulating hormone levels and testis volume, which guides the clinical documentation. 2

What the sources add

While the terminology authority defines the code hierarchy and active status, clinical literature provides operational context by explaining that extratesticular obstructions can occur between the rete testis and ejaculatory ducts. 1 2
