Sublux of unsp interphaln joint of l little finger, init

This code signifies a partial dislocation of an interphalangeal joint within the left little finger, where the specific joint (proximal or distal) is not documented. It indicates that the joint surfaces are no longer in proper alignment but remain in partial contact. This is the first time the patient is being treated for this specific injury.

Apply this code when documentation clearly states a subluxation of the left little finger's interphalangeal joint, but the physician does not specify whether it's the DIP or PIP joint. This code is appropriate for the initial visit or encounter for this injury, including emergency room visits or the first orthopedic consultation.

• Ensure "unspecified" is explicitly or implicitly stated for the interphalangeal joint.
• Verify the laterality is "left" and the digit is the "little finger."
• The 7th character "A" is crucial for an initial encounter; subsequent care will require different 7th characters.
