Diseases of male genital organs (N40-N53)

ICD-10 codes N40-N53 cover a broad spectrum of diseases affecting the male genital organs, including conditions related to the prostate, testes, penis, and associated structures. These codes are used for diagnosing and documenting disorders such as benign prostatic hyperplasia, prostatitis, male infertility, erectile dysfunction, and other inflammatory or structural disorders.

This range includes N40 for various forms of benign prostatic hyperplasia, distinguishing cases with or without lower urinary tract symptoms like urinary urgency or obstruction. Inflammatory diseases of the prostate, including acute and chronic prostatitis (N41), are coded here with synonyms like bacterial prostatitis or granulomatous prostatitis. Disorders such as hydrocele, spermatocele, torsion of the testis, and epididymitis fall under N43-N45. Male infertility, characterized by azoospermia or oligospermia, is detailed under N46 with specific codes reflecting etiology like drug-induced or systemic disease-related causes. N47-N50 address prepuce and penis disorders such as phimosis, balanoposthitis, penile leukoplakia, and priapism; each with relevant synonyms for clarity. Codes N52 and N53 classify male erectile and sexual dysfunctions, including vasculogenic causes, drug-induced impotence, ejaculatory dysfunction, and postprocedural complications. Using these codes enables precise recording and management of male genital conditions including inflammation, structural abnormalities, and sexual health issues.
