Subluxation of distal end of right ulna, initial encounter

This diagnosis code indicates a partial dislocation of the right ulna bone at its furthest point from the body, where it connects with the wrist. This means the joint surfaces are no longer perfectly aligned but still maintain some contact.

This code is appropriate for documenting an initial presentation or treatment for a patient experiencing a subluxation of the distal right ulna, often following a fall or direct trauma to the wrist. It is used when the patient is receiving active treatment for the injury.

• Ensure documentation specifies the right side and that it's a subluxation, not a complete dislocation.
• Confirm this is the initial encounter for this specific injury; subsequent encounters will require a different seventh character.
• Look for associated injuries, such as fractures or ligamentous tears, which would require additional codes.
