Trigger finger, unspecified ring finger

This code represents an unspecified type of trigger finger affecting the ring finger, where the specific hand (right or left) is not documented. Trigger finger, or stenosing tenosynovitis, is a condition where a finger gets stuck in a bent position due to inflammation and narrowing of the tendon sheath.

Use this code when documentation confirms trigger finger of the ring finger, but the laterality (right or left hand) is not specified. This typically occurs when the physician's notes indicate "trigger finger of ring finger" without further detail on the affected side.

• Avoid using this code if the laterality (right or left) is documented; instead, choose the more specific M65.341 (right) or M65.342 (left).
• Query the provider for laterality if possible to ensure the most specific code is assigned.
• Do not confuse with codes for other fingers (e.g., thumb, index, middle, little finger).
