Unsp injury of blood vessels at forarm lv, unsp arm, sequela

This code signifies a long-term complication or late effect resulting from an injury to an unspecified blood vessel in the forearm, where the specific arm (left or right) was not documented. This could include issues like chronic pain, nerve damage, or impaired circulation that persist after the initial injury has healed.

Apply this code when documenting a sequela of a forearm blood vessel injury where the type of vessel and the affected arm are not specified in the medical record. This is appropriate for follow-up encounters addressing residual problems from a past, poorly documented vascular trauma.

• Always strive for more specific codes if the type of blood vessel (e.g., artery, vein) or the affected arm (left/right) is known.
• This "S" code indicates a sequela; ensure the documentation clearly supports a late effect of a previous injury.
• Avoid using this code for acute injuries; it is exclusively for long-term complications.
