What it is
This code identifies an acute blood clot or embolus in the deep veins of the left upper arm, forearm, or related deep venous system. Use it when documentation clearly states an acute deep vein thrombosis in the left upper extremity.
Clinical signs
Typical findings include unilateral arm swelling, pain, tenderness, warmth, or visible venous distention. Clinical features vary; refer to documentation, imaging, and provider assessment for confirmation of deep venous involvement.
When to use this code
Use I82.622 when the record specifies acute embolism and thrombosis affecting deep veins of the left upper extremity. This includes cases documented as acute left upper extremity DVT, provided the laterality and acuity are clear. If the note is vague, check documentation before assigning this code.
Do not use for
Do not use this code for superficial vein thrombosis, chronic or old thrombosis, or clots in other body sites. If the laterality, acuity, or venous location is not documented, check documentation.
Coding tip
Confirm both acuity and left-sided upper-extremity location in the provider note before coding I82.622.
