Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- benign neoplasms of prostate adenoma, benign fibroadenoma fibroma myoma D29.1
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
- malignant neoplasm of prostate C61

Definitions from the National Library of Medicine for conditions coded in the N40 range.
Benign Prostatic Hyperplasia
A non-cancerous nodular enlargement of the prostate gland. It is characterized by the presence of epithelial cell nodules, and stromal nodules containing fibrous and smooth muscle elements. It is the most common urologic disorder in men, causing blockage of urine flow.
Nodular Prostate without Lower Urinary Tract Symptoms

About the N40 Code Range
Benign prostatic hyperplasia is a noncancerous, nodular enlargement of the prostate that can block urine flow.
N40 separates benign prostatic hyperplasia from nodular prostate, then distinguishes each by whether lower urinary tract symptoms are present. N40.0 and N40.1 describe benign prostatic hyperplasia without and with those symptoms. N40.2 and N40.3 make the same distinction for nodular prostate.
