ICD Code M66.28

ICD code M66.28 is used to classify and document a medical diagnosis of a spontaneous rupture of extensor tendons at a site other than those specifically listed in other ICD codes. Extensor tendons are responsible for straightening the fingers, wrist, and other joints, and a rupture can lead to significant functional impairment. This code helps healthcare providers accurately record and communicate the condition for treatment planning, billing, and statistical purposes.

When to use the ICD code M6628 for spontaneous rupture of extensor tendons, other site:

1. Clinical Presentation:

- Patient reports sudden onset of pain in the affected area.

- Visible deformity or abnormal positioning of the fingers or toes.

2. Physical Examination Findings:

- Palpable defect or gap in the tendon.

- Inability to extend the affected digit(s) at the proximal interphalangeal joint.

3. Functional Impairment:

- Loss of function in the affected extremity, particularly in extension.

- Difficulty performing daily activities that require hand or foot function.

4. Imaging Studies:

- MRI or ultrasound confirms the diagnosis of tendon rupture.

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

5. History of Trauma:

- Recent history of trauma or injury to the area, such as a fall or direct impact.

- Previous surgical history or conditions that may predispose to tendon rupture.

6. Chronic Conditions:

- Presence of underlying conditions that may weaken tendons, such as rheumatoid arthritis or diabetes.

7. Patient Demographics:

- Consideration of age, as spontaneous ruptures may be more common in certain age groups or populations.

8. Symptom Duration:

- Symptoms have persisted for a duration consistent with acute tendon rupture, typically within days of the injury.

By adhering to these diagnostic criteria and symptoms, healthcare providers can accurately determine the appropriate use of the ICD code M6628.

For the ICD code M66.28, which pertains to the spontaneous rupture of extensor tendons at other sites, the relevant CPT codes that may be applicable for treatment include:

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

2. CPT 25260 - Repair, tendon or muscle, flexor, forearm and/or wrist; primary, single, each tendon or muscle.

3. CPT 25270 - Repair, tendon or muscle, extensor, forearm and/or wrist; primary, single, each tendon or muscle.

4. CPT 26418 - Repair, tendon, extensor, hand, primary or secondary, without free graft, each tendon.

5. CPT 26480 - Transfer or transplant of tendon, carpometacarpal area or dorsum of hand; without free graft, each tendon.

6. CPT 26485 - Transfer or transplant of tendon, carpometacarpal area or dorsum of hand; with free graft (includes obtaining graft), each tendon.

These CPT codes are typically used for surgical procedures related to the repair or transfer of tendons in the upper extremities, which may be necessary for treating the condition associated with ICD code M66.28. It is important for healthcare providers to select the appropriate CPT code based on the specific procedure performed and the site of the tendon rupture.
