Personal history of pre-term labor

This code indicates a patient's past medical history of having experienced labor and delivery before 37 completed weeks of gestation. It signifies a prior pregnancy that ended prematurely, regardless of the outcome of that pregnancy.

Assign this code when documenting a patient's history of preterm labor in a non-pregnant state, or when the current encounter is not related to a current pregnancy. It is often used for risk assessment and counseling for future pregnancies.

• Do not use this code if the patient is currently pregnant and has a history of preterm labor; refer to the O09.21- series.
• This code is typically a secondary diagnosis, supporting the medical necessity of services related to reproductive health or risk assessment.
• Ensure documentation clearly states a history of preterm labor, not a current episode or complication.
