Tabular List of Diseases and Injuries

Type 1 Excludes

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.

Patient Education


Penis Disorders

Problems with the penis can cause pain and affect a man's sexual function and fertility. Penis disorders include:

  • Erectile dysfunction - inability to get or keep an erection
  • Priapism - a painful erection that does not go away
  • Peyronie's disease - bending of the penis during an erection due to a hard lump called a plaque
  • Balanitis - inflammation of the skin covering the head of the penis, most often in men and boys who have not been circumcised
  • Penile cancer - a rare form of cancer, highly curable when caught early

Testicular Disorders

Testicles, or testes, make male hormones and sperm. They are two egg-shaped organs inside the scrotum, the loose sac of skin behind the penis. It's easy to injure your testicles because they are not protected by bones or muscles. Men and boys should wear athletic supporters when they play sports.

You should examine your testicles monthly and seek medical attention for lumps, redness, pain or other changes. Testicles can get inflamed or infected. They can also develop cancer. Testicular cancer is rare and highly treatable. It usually happens between the ages of 15 and 40.
