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

This code signifies an injury to the ulnar artery within the wrist or hand region, where the specific nature of the injury (e.g., laceration, contusion) is not documented. It also indicates that the affected arm is not specified and that this is the first time the patient is receiving care for this particular injury.

This code is appropriate for initial encounters when a patient presents with signs and symptoms of ulnar artery damage in the wrist or hand, but the physician's documentation does not specify the exact type of injury or the laterality. This might occur in emergency department settings where a definitive diagnosis is pending further investigation.

• Always seek clarification from the provider if the specific type of ulnar artery injury or the affected arm can be determined.
• If a more specific injury (e.g., laceration, puncture) is documented, use the appropriate specific code from the S65.0- series.
• Ensure the "A" for initial encounter is correct; subsequent encounters will use "D" or "S" as appropriate.
