Questions About Q55Overview

What is the ICD-10 code for other congenital malformations of male genital organs?

Q55 is the ICD-10-CM category for other congenital malformations of male genital organs, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

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

No. This is a category header that groups the codes for other congenital malformations of male genital organs, and headers cannot be submitted on claims. Claims for other congenital malformations of male genital organs need a more specific code from this category, such as Q55.0, Q55.1, and Q55.20.

Can Q55 be reported with P83.5?

Not as a rule. The Excludes1 note on Q55 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).
