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

This code signifies the occurrence of labor contractions leading to cervical changes and delivery of the fifth fetus during the third trimester of pregnancy, prior to 37 completed weeks of gestation. It specifically identifies a preterm birth event for a multifetal pregnancy where the fifth fetus is delivered prematurely.

Apply this code when documentation clearly indicates preterm labor resulting in the delivery of the fifth fetus in a multifetal pregnancy during the third trimester. Supporting documentation should include gestational age at delivery, confirmation of preterm labor, and the specific fetal number delivered.

• Ensure the documentation specifies "fetus 5" for accurate assignment, as separate codes exist for other fetal numbers.
• Always sequence this code as a secondary diagnosis following the primary obstetric complication or outcome.
• Verify the gestational age at delivery falls within the third trimester (28 weeks 0 days to 36 weeks 6 days) and is less than 37 completed weeks.
