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

This code signifies a long-term or late effect of an unspecified injury to blood vessels in the wrist or hand, where the specific vessel involved is not documented, and the affected arm is also not specified. It indicates that the initial injury has resolved, but its lasting consequences are still present.

Use this code when a patient presents with a chronic condition or complication directly attributable to a past, unidentifiable blood vessel injury of the wrist or hand, and the laterality of the arm was not recorded. This applies to situations where the original injury is no longer acute but has left a permanent mark, such as chronic pain, diminished circulation, or nerve damage secondary to the vascular insult.

• This code is for sequelae only; do not use for acute injuries.
• Always strive for a more specific code if the blood vessel, type of injury, or laterality is documented.
• Requires an external cause code (V, W, X, Y) to fully describe the circumstances of the original injury, if known.
