22 weeks gestation of pregnancy

This code indicates that a pregnancy has reached 22 completed weeks of gestation. It is used to precisely document the duration of a pregnancy at a specific point in time, typically during an encounter.

This code is appropriate for any encounter where the gestational age of a pregnancy is being documented as 22 weeks. This includes routine prenatal visits, assessments for pregnancy-related conditions, or when reporting the gestational age for laboratory or imaging studies.

• Always confirm the gestational age from the physician's documentation, typically based on the last menstrual period (LMP) or ultrasound.
• Do not use this code as a primary diagnosis unless it is the sole reason for the encounter (e.g., for gestational age confirmation).
• Pair this code with other relevant codes describing the reason for the encounter or any complications of pregnancy.
