Quad preg, unsp num plcnta & amnio sacs, first trimester

This code signifies a pregnancy involving four fetuses during the first trimester. It indicates that the specific number of placentas (chorionicity) and amniotic sacs (amnionicity) has not yet been determined or documented. This is an early-stage diagnosis of a high-order multiple gestation.

Apply this code when documentation explicitly states a quadruplet pregnancy in the first trimester, and there is no further specification regarding chorionicity or amnionicity. This is typically used following initial ultrasound confirmation of four gestational sacs or fetuses.

• Ensure the documentation clearly specifies "quadruplet" and "first trimester."
• Do not use this code if chorionicity or amnionicity is known; instead, select a more specific O30.2- subcategory.
• Sequence this code as the primary diagnosis when the quadruplet pregnancy is the focus of the encounter.
