Phlebitis and thrombophlebitis of lower extremities, unsp

This code signifies inflammation of a vein (phlebitis) or inflammation of a vein with associated clot formation (thrombophlebitis) occurring in the lower limbs. It is used when the specific vein affected (e.g., superficial, deep) is not documented.

Apply this code when documentation indicates phlebitis or thrombophlebitis of the lower extremity without further specification of the vessel involved. This code is appropriate when the provider's assessment is limited to "lower extremity thrombophlebitis" or "phlebitis of leg" without additional detail.

• Avoid using this code if the documentation specifies a superficial or deep vein; instead, use more specific codes from the I80 series.
• Always review documentation for laterality (right, left, bilateral) and specific vein involvement to ensure the most precise code is selected.
• This code does not differentiate between acute and chronic conditions; if acuity is documented, consider if a more specific code is available.
