Unsp injury of blood vessel of left ring finger, sequela

This code signifies a long-term or late effect resulting from an unspecified injury to a blood vessel in the left ring finger. The initial injury has healed, but the patient continues to experience residual symptoms or complications directly attributable to that past vascular trauma.

Apply this code when documenting a patient presenting with ongoing issues such as chronic pain, numbness, altered sensation, or impaired circulation in the left ring finger, and the medical record clearly links these symptoms to a previously sustained, unspecified blood vessel injury. This code is appropriate when the acute phase of the original injury has passed, and the current encounter addresses the lasting consequences.

• Ensure documentation explicitly states the condition is a "sequela" or "late effect" of a prior injury.
• Verify the affected digit is specifically the left ring finger and the injury involved a blood vessel.
• Do not use for acute injuries; this code is exclusively for chronic or residual conditions.
