M65342 - Trigger finger condition affecting the left ring finger

International Classification of Diseases

Last updated: 10/3/2025

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

Trigger finger is a condition where your left ring finger gets stuck in a bent position and may snap straight like pulling and releasing a trigger. This happens when the tendon that bends your finger becomes inflamed or irritated, making it difficult to move smoothly through the tunnel-like sheath that surrounds it. You may experience pain, stiffness, a catching sensation, or a popping sound when trying to straighten your finger. The finger may also feel locked in a bent position, especially in the morning.

Additional Information

This is a common condition that often responds well to conservative treatment. Early intervention typically leads to better outcomes. The condition may be related to repetitive gripping activities, diabetes, or rheumatoid arthritis.
