Other venous complications in pregnancy, second trimester

This code signifies a pregnant patient in her second trimester experiencing venous complications not otherwise specified, such as pelvic vein thrombosis, ovarian vein thrombosis, or other unusual venous issues. It excludes common conditions like deep vein thrombosis (DVT) or superficial thrombophlebitis, which have their own specific codes.

Apply this code when documentation clearly indicates a venous complication during the second trimester that doesn't fit more specific ICD-10-CM codes for venous issues in pregnancy. This often involves conditions identified through imaging studies like ultrasound or MRI, or based on clinical signs and symptoms not attributable to DVT or superficial phlebitis.

• Always ensure the documentation specifies the second trimester for accurate code assignment.
• Distinguish from O22.3- (Deep phlebothrombosis in pregnancy) and O22.2- (Superficial thrombophlebitis in pregnancy).
• Code any associated specific venous condition (e.g., I82.21- for superior vena cava thrombosis) as a secondary diagnosis if known and not fully encompassed by O22.8X2.
