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 Q55.3Overview

What is the ICD-10 code for atresia of vas deferens?

The ICD-10-CM code for atresia of vas deferens is Q55.3 (sometimes written as Q553). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is Q55.3 (Other congenital malformations of male genital organs) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report atresia of vas deferens on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does Q55.3 group to?

When atresia of vas deferens is the principal diagnosis on an inpatient stay, it groups to MS-DRG 729, 730, with relative weights from 0.6595 to 1.0553 depending on complications. Higher weights mean higher Medicare reimbursement.

Is Q55.3 exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for atresia of vas deferens on inpatient claims. The code appears in the Congenital malformations of genital organs (Q50-Q56) range of the CMS exempt list.

Can Q55.3 be reported with P83.5?

Not as a rule. The Excludes1 note at Q55, which applies to Q55.3, lists "congenital hydrocele (P83.5)". 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).
