About N92

N92 is the ICD-10-CM diagnosis code for excessive, frequent and irregular menstruation. It belongs to block N80-N98 (noninflammatory disorders of female genital tract) and chapter 14 (diseases of the genitourinary system). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: N92.0 (cycle), N92.1 (cycle), N92.2 (puberty), N92.3 (bleeding), N92.4 (period), N92.5 (menstruation) and N92.6 (unspecified).

Don't report N92 together with the conditions in its Excludes1 note: postmenopausal bleeding (N95.0) and precocious puberty (menstruation) (E30.1).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
