Other venous complications in pregnancy, unsp trimester

This code signifies the presence of various venous complications during pregnancy that are not specifically categorized elsewhere. It encompasses conditions such as superficial thrombophlebitis, venous insufficiency, or varicose veins that develop or are exacerbated during gestation, where the specific trimester is not documented.

Apply this code when documentation indicates a venous complication in a pregnant patient, but the specific type of complication is not detailed enough to assign a more precise O22 subcategory (e.g., O22.0 for varicose veins of lower extremity, O22.2 for superficial thrombophlebitis). It is also used when the medical record fails to specify the trimester of pregnancy.

• Always attempt to query for a more specific diagnosis and trimester if possible to allow for more precise coding.
• Do not use this code if a more specific O22 subcategory (e.g., deep vein thrombosis, phlebitis, or specific varicose vein locations) is documented.
• This code should be sequenced as a secondary diagnosis following the code for the pregnancy itself (e.g., Z3A.xx for weeks of gestation).
