Questions About N46Overview

What is the ICD-10 code for male infertility?

N46 is the ICD-10-CM category for male infertility, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is N46 (Male infertility) a billable code?

No. This is a category header that groups the codes for male infertility, and headers cannot be submitted on claims. Claims for male infertility need a more specific code from this category, such as N46.01, N46.021, and N46.022.

Can N46 be reported with Z98.52?

Not as a rule. The Excludes1 note on N46 lists "vasectomy status (Z98.52)". 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).
