Unsp injury of blood vessel of unspecified finger, sequela

This code signifies a long-term or late effect resulting from an unspecified injury to a blood vessel in any finger, where the specific finger or type of blood vessel is not documented. It indicates that the initial injury has resolved, but residual symptoms or conditions persist.

Apply this code when a patient presents with a current condition directly attributable to a past, unspecified blood vessel injury of an unspecified finger. This is appropriate for follow-up encounters where the sequela is being treated or evaluated, and the original acute injury is no longer active.

• Always sequence this code after the code(s) describing the specific sequela being treated (e.g., chronic pain, nonunion, nerve damage).
• Avoid using this code if the specific finger or blood vessel is known; instead, use a more precise code from the S65.5 category.
• Ensure documentation clearly links the current condition to a previous blood vessel injury of the finger.
