Trigger finger, unspecified finger

This code describes a stenosing tenosynovitis affecting an unspecified flexor tendon of the hand, leading to a catching or locking sensation during finger flexion and extension. It is characterized by inflammation and thickening of the tendon sheath, impeding smooth gliding of the tendon.

Apply this code when documentation indicates a diagnosis of trigger finger without specifying the affected digit. This is appropriate when the physician's notes confirm the condition but do not identify which finger is involved. Supporting documentation would include clinical notes detailing symptoms consistent with trigger finger, such as catching, locking, or pain with movement, but lacking specific finger identification.

• Do not use this code if the specific finger affected by trigger finger is documented (e.g., thumb, index finger).
• Always query the provider for clarification on the specific digit if not documented, to allow for more precise coding (e.g., M65.31-M65.39).
• Consider laterality if specified in the documentation, as more specific codes exist for right, left, or bilateral involvement.
