From Block Q50-Q56 Congenital malformations of genital organs applies to 91 codes
  • androgen insensitivity syndrome (E34.5-)
  • syndromes associated with anomalies in the number and form of chromosomes (Q90-Q99)

Patient EducationClinical

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.

Questions About Q53Overview

What is the ICD-10 code for undescended and ectopic testicle?

Q53 is the ICD-10-CM category for undescended and ectopic testicle, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is Q53 (Undescended and ectopic testicle) a billable code?

No. This is a category header that groups the codes for undescended and ectopic testicle, and headers cannot be submitted on claims. Claims for undescended and ectopic testicle need a more specific code from this category, such as Q53.00, Q53.01, and Q53.02.

Can Q53 be reported with a code from E34.5?

Not as a rule. The Excludes1 note at block Q50-Q56, which applies to Q53, lists "androgen insensitivity syndrome (E34.5-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
