Placental infarction, second trimester

This code signifies the presence of an area of ischemic necrosis within the placenta during the second trimester of pregnancy. This condition can impair placental function, potentially leading to fetal growth restriction, pre-eclampsia, or other adverse pregnancy outcomes.

Assign this code when documentation clearly indicates a diagnosis of placental infarction identified during the second trimester (weeks 14 through 27+6 days of gestation). Supporting documentation typically includes ultrasound findings, pathology reports from placental examination, or clinical notes detailing the diagnosis.

• Ensure the trimester is explicitly documented as "second trimester" to support this specific code.
• Do not confuse with placental abruption or placenta previa; these are distinct conditions with different codes.
• Code any associated maternal or fetal conditions, such as intrauterine growth restriction (IUGR), as secondary diagnoses.
