Trigger finger, left little finger

This code signifies stenosing tenosynovitis affecting the flexor tendon of the left little finger, characterized by a catching or locking sensation during finger flexion and extension. It results from inflammation and thickening of the tendon sheath, impeding smooth tendon gliding.

Apply this code when documentation clearly indicates a diagnosis of trigger finger specifically affecting the little finger of the left hand. Supporting documentation should include physical exam findings such as palpable nodule, tenderness, or the characteristic locking phenomenon.

• Ensure the documentation specifies "left little finger" to avoid laterality and digit-specific coding errors.
• Do not confuse with other types of tenosynovitis or other finger conditions like Dupuytren's contracture.
• Consider sequencing this code after any underlying systemic conditions that may contribute to trigger finger, if applicable.
