ICD-10-CM Code N40
Enlarged prostate

NON-BILLABLE

Non-Billable Code

Non-Billable means the code is not sufficient justification for admission to an acute care hospital when used a principal diagnosis. Use a child code to capture more detail.

| ICD-10 from 2011 - 2016

ICD Code N40 is a non-billable code. To code a diagnosis of this type, you must use one of the four child codes of N40 that describes the diagnosis 'enlarged prostate' in more detail.

N40 Enlarged prostate NON-BILLABLE

The ICD code N40 is used to code Benign prostatic hyperplasia

Benign prostatic hyperplasia (BPH), also called benign enlargement of the prostate (BEP or BPE), adenofibromyomatous hyperplasia and benign prostatic hypertrophy (technically incorrect usage), is a benign (noncancerous) increase in size of the prostate. BPH involves hyperplasia of prostatic stromal and epithelial cells, resulting in the formation of large, fairly discrete nodules in the transition zone of the prostate. When sufficiently large, the nodules impinge on the urethra and increase resistance to flow of urine from the bladder. This is commonly referred to as "obstruction," although the urethral lumen is no less patent, only compressed. Resistance to urine flow requires the bladder to work harder during voiding, possibly leading to progressive hypertrophy, instability, or weakness (atony) of the bladder muscle. BPH involves hyperplasia (an increase in the number of cells) rather than hypertrophy (a growth in the size of individual cells), but the two terms are often used interchangeably, even among urologists. Although prostate specific antigen levels may be elevated in these patients because of increased organ volume and inflammation due to urinary tract infections, BPH does not lead to cancer or increase the risk of cancer.

Coding Notes for N40 Info for medical coders on how to properly use this ICD-10 code

Code Includes Notes: Includes Includes notes further define, or give examples of, conditions included in the section.: Adenofibromatous hypertrophy of prostate; Benign hypertrophy of the prostate; Benign prostatic hyperplasia; Benign prostatic hypertrophy; BPH; Nodular prostate; Polyp of prostate

Code Type-1 Excludes: Type-1 Excludes Type-1 Excludes mean the conditions excluded are mutually exclusive and should never be coded together. Excludes 1 means "do not code here.": Benign neoplasms of prostate (adenoma, benign) (fibroadenoma) (fibroma) (myoma) - instead, use code D29.1

Code Type-2 Excludes: Type-2 Excludes Type-2 Excludes means the excluded conditions are different, although they may appear similar. A patient may have both conditions, but one does not include the other. Excludes 2 means "not coded here.": Malignant neoplasm of prostate - instead, use Code C61
