Valid for Submission

O42.92 is a billable diagnosis code used to specify a medical diagnosis of full-term premature rupture of membranes, unspecified as to length of time between rupture and onset of labor. The code O42.92 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.

The ICD-10-CM code O42.92 might also be used to specify conditions or terms like premature rupture of membranes in full term pregnancy with onset of labor unknown.

The code O42.92 is applicable to female patients aged 12 through 55 years inclusive. It is clinically and virtually impossible to use this code on a non-female patient outside the stated age range.

Unspecified diagnosis codes like O42.92 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
