Placentitis, unspecified trimester, fetus 2

This code signifies inflammation of the placenta occurring at an unspecified point during pregnancy, specifically affecting the second fetus in a multiple gestation. Placentitis can lead to adverse pregnancy outcomes, including preterm labor, fetal distress, and infection.

Apply this code when documentation clearly indicates placentitis in a multiple gestation pregnancy, and the specific trimester of onset is not recorded. The medical record must specify that the condition affects the second fetus. Supporting documentation includes pathology reports, physician notes detailing placental inflammation, and ultrasound findings.

• Ensure the documentation explicitly identifies "fetus 2" in a multiple gestation to differentiate from other fetuses.
• Avoid using this code if the trimester of placentitis is known; instead, select the appropriate trimester-specific code.
• Confirm that the diagnosis is indeed placentitis and not another placental condition like placental abruption or previa.
