Venous complication in pregnancy, unsp, first trimester

This code signifies any unspecific venous complication occurring during the first trimester of pregnancy. This could encompass a range of issues such as deep vein thrombosis (DVT), superficial thrombophlebitis, or varicose vein complications, where the specific type of venous issue is not documented.

This code is appropriate when a pregnant patient in her first trimester presents with symptoms of a venous complication, but the medical record does not specify the exact nature of the complication. Documentation supporting its use would include notes indicating "venous complication," "phlebitis," or "thrombosis" without further detail on the specific vessel or type, and clearly stating the first trimester of pregnancy.

• Always attempt to query for a more specific diagnosis if the documentation is unclear regarding the type of venous complication.
• Ensure the documentation explicitly states "first trimester" to justify the 7th character "1".
• Do not use this code if the venous complication is specified (e.g., DVT of lower extremity); instead, code the specific condition with an O-code indicating pregnancy.
