36 weeks gestation of pregnancy

This code indicates that a pregnant patient has reached 36 completed weeks of gestation. It signifies a specific point in the third trimester, close to term, and is used to track the progression of the pregnancy.

This code is used when documenting the gestational age of a pregnancy at 36 weeks. It is frequently applied during routine prenatal visits, hospital admissions for pregnancy-related conditions, or when assessing fetal development and maternal health at this specific stage.

• Always use in conjunction with a code from category O09 (Supervision of high-risk pregnancy) or O80 (Encounter for full-term uncomplicated delivery) if applicable.
• Ensure the gestational age documented in the medical record precisely matches 36 weeks for accurate coding.
• Do not use if the gestational age is estimated to be 35 weeks 6 days or less, or 36 weeks 1 day or more; use the appropriate Z3A code for that specific week.
