Preterm labor second tri w preterm del second tri, fetus 5

This code signifies the onset of labor before 37 completed weeks of gestation, specifically occurring and resulting in delivery during the second trimester (weeks 14 through 27+6 days), and pertains to the fifth fetus in a multiple gestation pregnancy. It indicates that the uterine contractions led to cervical changes and subsequent delivery within this gestational window.

Apply this code when a pregnant patient experiences labor that begins and culminates in delivery during the second trimester. Documentation should clearly state "preterm labor" and "preterm delivery" within the second trimester, along with the specific fetal number (e.g., "fetus 5"). This code is appropriate for cases where the delivery of the specified fetus occurs preterm.

• Ensure the documentation explicitly states both "preterm labor" and "preterm delivery" occurred in the second trimester.
• Verify the fetal number (e.g., fetus 5) is clearly identified in the medical record for correct character assignment.
• Sequence this code as the principal diagnosis when the reason for the encounter is the preterm labor leading to delivery.
