In simple words: This code indicates that a pregnant woman went into labor too early, before 37 weeks of pregnancy, but did not deliver the baby at that time.

Preterm labor without delivery refers to the onset of uterine contractions and cervical changes before 37 completed weeks of gestation, but without resulting in delivery at the time of diagnosis.

Example 1: A pregnant woman at 32 weeks gestation presents with regular uterine contractions and cervical dilation, but delivery is successfully postponed with tocolytic medication., A pregnant woman at 35 weeks gestation experiences contractions and cervical changes. She is admitted for observation and monitoring, but labor eventually stops without delivery., A pregnant woman at 36 weeks gestation has regular, painful contractions and a shortened cervix.She is given medication to slow or stop labor, and delivery does not occur at that time.

Documentation should include gestational age, frequency and duration of contractions, cervical examination findings (dilation and effacement), and any interventions provided (e.g., tocolytic therapy).

** Use additional code from category Z3A, Weeks of gestation, to identify the specific week of the pregnancy, if known. This code is for use only on maternal records, never on newborn records.
