Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the Q53 range.
Undescended Testes
The failure of one or both testes of a male fetus to descend from the abdomen into the scrotum during the late part of pregnancy. If not surgically corrected in early childhood, males may be at increased risk for testicular cancer later in life.
About the Q53 Code Range
These congenital genital organ conditions involve testicles described as undescended or ectopic, meaning out of place.
Q53.0 groups ectopic testis by whether the side is unspecified, unilateral, or bilateral. The undescended testicle groups distinguish unilateral Q53.1, bilateral Q53.2, and unspecified Q53.9 cases. Further unilateral and bilateral subdivisions name abdominal, intraabdominal, inguinal, ectopic perineal, and high scrotal locations.
