Unsp injury of ulnar artery at wrs/hnd lv of unsp arm, subs

This code signifies an unspecified injury to the ulnar artery in the wrist or hand region of an unspecified arm, occurring during the healing phase after initial treatment. The nature of the arterial damage is not specified, indicating a lack of detailed documentation regarding the type of injury (e.g., laceration, contusion, transection).

Apply this code when a patient presents for follow-up care, such as wound checks, dressing changes, or physical therapy, for an ulnar artery injury at the wrist or hand level where the specific arm (left or right) was not documented at the initial encounter. This is appropriate when the initial treatment has concluded, and the patient is in the recovery phase.

• Ensure documentation clearly indicates a subsequent encounter for an unspecified ulnar artery injury.
• Avoid using this code if the specific arm (left or right) is known; instead, use the more specific codes (S65.01-S65.02-).
• If the type of ulnar artery injury is specified (e.g., laceration), a more precise code from the S65.0- category should be selected.
