Unsp inj blood vessels at wrs/hnd lv of left arm, sequela

This code signifies a long-term complication or late effect resulting from an unspecified injury to a blood vessel, other than a major artery or vein, in the wrist or hand region of the left arm. It indicates that the initial injury has healed, but residual symptoms or conditions related to that injury are still present.

Use this code when documenting a patient presenting with a chronic issue, such as persistent pain, numbness, or impaired circulation, that is directly attributable to a past, unspecified blood vessel injury in the left wrist or hand. This applies when the acute phase of the original injury has passed, and the current encounter addresses the lasting consequences.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a previous blood vessel injury in the specified anatomical area.
• Do not use this code for acute injuries; instead, select an appropriate acute injury code from the S60-S69 range.
