ICD Code M65.321

ICD code M65321 is used to identify the medical condition known as "trigger finger" specifically affecting the right index finger. Trigger finger, medically referred to as stenosing tenosynovitis, is a condition where one of your fingers gets stuck in a bent position and may straighten with a snap, similar to a trigger being pulled and released. This code is part of the International Classification of Diseases (ICD) system, which is used by healthcare providers to classify and code all diagnoses, symptoms, and procedures recorded in conjunction with hospital care in the United States. The specificity of this code helps in accurately documenting the condition for treatment, billing, and statistical purposes.

When to use the ICD code for Trigger Finger (right index finger):

1. Patient Presentation:

- Patient reports pain or discomfort in the right index finger.

2. Physical Examination Findings:

- Tenderness localized to the palmar aspect of the right index finger.
