Inj ulnar artery at wrist and hand level of unsp arm, subs

This code signifies a follow-up encounter for an injury to the ulnar artery in the wrist or hand, where the specific type of injury is not further detailed (e.g., not a laceration or puncture). It indicates that the patient is receiving active treatment or follow-up care for a previously diagnosed "other specified" ulnar artery injury.

Use this code for subsequent visits related to the treatment of an ulnar artery injury at the wrist or hand that doesn't fit more specific injury codes. This includes scenarios like wound care, monitoring for complications, or physical therapy following the initial injury. It is appropriate when the arm laterality was not documented or is unknown.

• Ensure the encounter is for active treatment or follow-up care, not for sequelae.
• Always attempt to identify the specific type of ulnar artery injury (e.g., laceration, puncture) and the affected arm (left or right) if documented, to use a more specific code.
• If the injury is to a different artery or location, select the appropriate code from the S65 series.
