27 weeks gestation of pregnancy

This code indicates that a pregnant patient is precisely 27 weeks into her gestational period. It is used to track the progression of the pregnancy and is based on the estimated date of conception or last menstrual period.

This code is used for routine prenatal visits, particularly when documenting the gestational age at the time of the encounter. It is also applicable when a specific gestational age is required for medical decision-making, such as scheduling tests or procedures.

• Always confirm the gestational age with the provider's documentation, typically from the last menstrual period (LMP) or ultrasound.
• Do not use this code if the gestational age is expressed as a range or is not precisely 27 weeks.
• This code is often used in conjunction with other codes describing the reason for the encounter or any complications.
