Menstruation

Menstruation, also called a period, is normal vaginal bleeding that happens as part of the monthly cycle in women and girls. Every month, the body prepares for pregnancy. If pregnancy does not happen, the uterus (womb) sheds its lining. This blood and tissue leave the body through the vagina.

Questions About N92Overview

What is the ICD-10 code for excessive, frequent and irregular menstruation?

N92 is the ICD-10-CM category for excessive, frequent and irregular menstruation, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is N92 (Excessive, frequent and irregular menstruation) a billable code?

No. This is a category header that groups the codes for excessive, frequent and irregular menstruation, and headers cannot be submitted on claims. Claims for excessive, frequent and irregular menstruation need a more specific code from this category, such as N92.0, N92.1, and N92.2.

Can N92 be reported with N95.0?

Not as a rule. The Excludes1 note on N92 lists "postmenopausal bleeding (N95.0)". 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).
