Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the N42 range.
Prostatic Intraepithelial Neoplasia
A premalignant change arising in the prostatic epithelium, regarded as the most important and most likely precursor of prostatic adenocarcinoma. The neoplasia takes the form of an intra-acinar or ductal proliferation of secretory cells with unequivocal nuclear anaplasia, which corresponds to nuclear grade 2 and 3 invasive prostate cancer.
About the N42 Code Range
ICD-10 code N42 covers a diverse set of other and unspecified disorders of the prostate. These codes are used to identify various prostate conditions that do not fit into common categories like benign prostatic hyperplasia or prostate cancer.
The section includes N42.0 for calculus of prostate, which refers to prostate stones, and N42.1, addressing congestion and hemorrhage of prostate, often called prostatic congestion or bleeding varices. It also covers a range of dysplasias under N42.3, including prostatic intraepithelial neoplasia (N42.31) and atypical small acinar proliferation (N42.32), which are precancerous changes in prostate tissue. Other specified disorders, like prostatodynia syndrome (N42.81) — pain of the prostate—and prostatic cyst (N42.83) are also included. Code N42.89 covers a broad array of specific prostate issues, such as asymmetry, strictures, infarction, fistulas, and calcification. Lastly, N42.9 is for an unspecified prostate disorder when the exact nature is not detailed. Using these codes helps accurately describe and document less common prostate conditions for diagnosis and treatment purposes, supporting precise medical coding for conditions encountered beyond typical prostate diagnoses.
