Preterm labor third tri w preterm delivery third tri, unsp

This diagnosis code signifies the onset of labor before 37 weeks of gestation, specifically occurring during the third trimester, which results in a preterm delivery also within the third trimester. It indicates that the patient experienced uterine contractions leading to cervical changes and delivered prematurely.

This code is appropriate when a pregnant patient in her third trimester (28 weeks 0 days to 40 weeks 6 days) presents with signs and symptoms of preterm labor and subsequently delivers the infant prematurely. Documentation should clearly state both preterm labor and preterm delivery occurring in the third trimester.

• Ensure documentation specifies both "preterm labor" and "preterm delivery" in the third trimester.
• Do not use this code if the delivery occurs in the second trimester; refer to codes in the O60.12x series.
• Always sequence this code as the principal diagnosis when it is the reason for the admission.
