ICD Code M66.212

ICD code M66.212 is used to classify and document the medical condition known as a spontaneous rupture of extensor tendons in the left shoulder. This code is part of the International Classification of Diseases, 10th Revision (ICD-10), which is a system used by healthcare providers to standardize the diagnosis of medical conditions. A spontaneous rupture of extensor tendons refers to the sudden tearing or breaking of the tendons that help extend or straighten the shoulder without any apparent external trauma or injury. This condition can lead to pain, weakness, and limited range of motion in the affected shoulder, and it often requires medical evaluation and treatment to restore function.

When to use the ICD code for spontaneous rupture of extensor tendons, left shoulder:

1. Clinical Diagnosis: A healthcare provider has clinically diagnosed a spontaneous rupture of the extensor tendons in the left shoulder based on patient evaluation.

2. Patient Symptoms:

- Sudden onset of pain in the left shoulder.

- Inability to extend the fingers or wrist on the affected side.

- Swelling or bruising around the shoulder joint.

- Limited range of motion in the left shoulder.

- Tenderness upon palpation of the shoulder area.

3. Imaging and Diagnostic Tests:

- MRI or ultrasound imaging confirms the rupture of the extensor tendons.

- X-rays may be performed to rule out associated fractures or other injuries.

4. History of Trauma: The patient has a history of recent trauma or injury to the left shoulder that could have contributed to the tendon rupture.

5. Exclusion of Other Conditions: Other potential causes of shoulder pain and dysfunction have been ruled out, ensuring that the diagnosis specifically pertains to the spontaneous rupture of extensor tendons.

6. Treatment Plan: A treatment plan is established that may include surgical intervention, physical therapy, or other management strategies specific to the diagnosis of tendon rupture.

7. Follow-Up Care: Documentation of follow-up care and monitoring of the patient's recovery process, including any changes in symptoms or functional ability.

These criteria should be met to appropriately assign the relevant ICD code for the diagnosis.

For the ICD code M66.212, which pertains to the spontaneous rupture of extensor tendons in the left shoulder, the relevant CPT codes that may be applicable for treatment include:

1. 23410 - Repair of ruptured musculotendinous cuff (e.g., rotator cuff) open; acute.

2. 23412 - Repair of ruptured musculotendinous cuff (e.g., rotator cuff) open; chronic.

3. 23420 - Reconstruction of complete shoulder (rotator) cuff avulsion, chronic (includes acromioplasty).

4. 29827 - Arthroscopy, shoulder, surgical; with rotator cuff repair.

5. 24341 - Repair, tendon or muscle, upper arm or elbow, each tendon or muscle, primary or secondary (excludes rotator cuff).
