Preterm labor third tri w preterm del third tri, fetus 2

This code signifies the onset of labor before 37 completed weeks of gestation, specifically occurring during the third trimester, which results in a preterm delivery. The "2" in the seventh character indicates that this diagnosis pertains to the second fetus in a multiple gestation pregnancy.

Apply this code when a pregnant patient in her third trimester experiences documented preterm labor contractions leading to the birth of the second fetus prior to 37 weeks. Documentation should clearly state the gestational age at delivery, the occurrence of preterm labor, and that it is the second fetus being delivered.

• Always confirm the specific fetus number in multiple gestations; a different seventh character applies to other fetuses.
• Ensure documentation specifies both preterm labor and preterm delivery; if only one is present, a different code may be appropriate.
• Sequence this code as the principal diagnosis when it is the reason for the admission/encounter.
