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.
- congenital hydrocele P83.5

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the N43 range.
Spermatocele
A cystic dilation of the EPIDIDYMIS, usually in the head portion (caput epididymis). The cyst fluid contains dead SPERMATOZOA and can be easily differentiated from TESTICULAR HYDROCELE and other testicular lesions.
About the N43 Code Range
Among diseases of male genital organs, hydroceles appear alongside spermatoceles of the epididymis.
The hydrocele codes distinguish encysted (N43.0) and infected (N43.1) hydroceles from other (N43.2) or unspecified (N43.3) hydroceles. Spermatocele of the epididymis (N43.4) is further divided into unspecified, single, and multiple forms.
