Lacerat ulnar artery at wrs/hnd lv of unsp arm, sequela

This code describes the long-term effects or complications resulting from a previous laceration to the ulnar artery in the wrist or hand of an unspecified arm. These sequelae could include chronic pain, nerve damage, impaired circulation, or functional limitations that persist after the initial injury has healed.

Use this code when documenting conditions that are residual effects of a past ulnar artery laceration at the wrist or hand level, where the specific arm (left or right) is not documented. This applies to follow-up encounters for ongoing management of these chronic issues, not for the initial acute injury.

• Always assign a secondary code to specify the exact nature of the sequela (e.g., chronic pain, nonunion, nerve deficit).
• Ensure documentation clearly links the current condition to the previous ulnar artery laceration.
• Do not use this code for acute or active lacerations; those require an acute injury code.
