There is no single diagnostic code for dysfunc-
tional uterine bleeding. Therefore it was defined in ICD-
9 as 626.2 (other dysfunctional uterine bleeding or
functional uterine haemorrhage not otherwise speci-
fied), 626.8 (other dysfunctional uterine bleeding or
functional uterine haemorrhage not otherwise specified)
or 627.0 (premenopausal menorrhagia). Dysfunctional
uterine bleeding was defined in ICD-10 as N92 (exces-
sive, frequent and irregular menstruation), N93.8 (other
specified abnormal uterine and vaginal bleeding-dys-
functional uterine or vaginal bleeding), or N93-9 (abnor-
mal uterine and vaginal bleeding, unspecified).
