O42.12 is a billable ICD code used to specify a diagnosis of full-term premature rupture of membranes, onset of labor more than 24 hours following rupture. A 'billable code' is detailed enough to be used to specify a medical diagnosis.


The ICD code O42 is used to code Premature rupture of membranes

Premature rupture of membranes (PROM), or pre-labor rupture of membranes, is a condition that can occur in pregnancy. It is defined as rupture of membranes (breakage of the amniotic sac), commonly called breaking of the mother's water(s), more than 1 hour before the onset of labor. The sac (consisting of 2 membranes, the chorion and amnion) contains amniotic fluid, which surrounds and protects the fetus in the uterus (womb). After rupture, the amniotic fluid leaks out of the uterus through the vagina.

Specialty: Obstetrics
MeSH Code: D005322
ICD 9 Code: 658.1

A fetus surrounded by the amniotic sac which is enclosed by fetal membranes. In PROM, these membranes rupture before labor starts.
