False labor before 37 completed weeks of gest, second tri

This code signifies the occurrence of irregular uterine contractions that do not lead to cervical change in a pregnant patient who is between 14 weeks 0 days and 27 weeks 6 days of gestation. These contractions are often uncomfortable but do not progress to true labor.

Apply this code when a pregnant patient in her second trimester presents with symptoms of false labor, such as Braxton Hicks contractions, that are not associated with cervical dilation or effacement. Documentation should clearly indicate the gestational age and the absence of true labor signs.

• Ensure documentation specifies "false labor" or "Braxton Hicks" and the gestational age falls within the second trimester.
• Do not use this code if there is any evidence of cervical change, as this would indicate true preterm labor.
• Distinguish from O47.00 (false labor, unspecified trimester) and O47.03 (false labor before 37 completed weeks of gestation, third trimester).
