Preterm labor third tri w preterm del third tri, fetus 1

This code signifies the onset of labor contractions before 37 completed weeks of gestation, occurring during the third trimester, which results in a preterm delivery. It specifically applies to the first fetus in a multiple gestation or the only fetus in a singleton pregnancy.

Apply this code when documentation confirms a patient in her third trimester experiences preterm labor leading to a preterm birth. Supporting documentation includes physician notes detailing preterm contractions, cervical changes, and the actual delivery occurring before 37 weeks, specifically for fetus 1.

• Ensure the documentation clearly specifies "preterm delivery" in addition to "preterm labor."
• Verify the gestational age at the time of delivery to confirm it falls within the preterm range (before 37 completed weeks).
• This code is for the first fetus; use appropriate codes for subsequent fetuses in a multiple gestation.
