Phlbts and thombophlb of superfic vessels of unsp low extrm

This code describes inflammation of a superficial vein, often accompanied by thrombus formation, occurring in an unspecified lower extremity. It signifies a non-deep vein thrombosis (DVT) process affecting veins closer to the skin surface.

Use this code when documentation indicates phlebitis or thrombophlebitis of a superficial vein in the lower limb, but the specific leg (right or left) is not documented. This typically presents with localized pain, redness, warmth, and a palpable cord along the affected vein.

• Avoid using this code if the laterality (right or left lower extremity) is specified in the medical record; instead, use a more specific code from the I80.0- series.
• Do not confuse superficial thrombophlebitis with deep vein thrombosis (DVT); DVT codes are found in the I82.xx series.
• Ensure documentation clearly states "superficial" to differentiate from unspecified phlebitis or thrombophlebitis of other vessels.
