ICD Code M65.351

ICD code M65351 is used to identify the medical condition known as "trigger finger" specifically affecting the right little finger. Trigger finger, medically termed stenosing tenosynovitis, occurs when the finger becomes stuck in a bent position and may snap straight suddenly, like a trigger being pulled and released. This condition is caused by inflammation or narrowing of the sheath surrounding the tendon in the affected finger, leading to pain, stiffness, and a sensation of locking or catching when the finger is moved. The code M65351 helps healthcare providers accurately document and communicate this specific diagnosis for treatment planning and billing purposes.

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

1. Patient Presentation: The patient reports difficulty in extending the right little finger.

2. Symptoms:

- Pain or tenderness in the palm or base of the little finger.

- Stiffness in the right little finger, particularly in the morning.

- A sensation of locking or catching when trying to straighten the finger.

- Swelling at the base of the right little finger.

3. Physical Examination Findings:

- Palpable nodule or thickening in the flexor tendon sheath of the right little finger.

- Positive trigger sign during the examination (e.g., the finger locks in a bent position).

4. Duration of Symptoms: Symptoms have persisted for a significant period, typically more than a few weeks.

5. Impact on Daily Activities: The condition affects the patient's ability to perform daily tasks, such as gripping or holding objects.

6. Exclusion of Other Conditions: Other potential causes of finger pain or dysfunction have been ruled out through clinical evaluation or imaging, confirming the diagnosis of trigger finger.
