ICD Code M66.252

ICD code M66.252 is used to classify and document a medical diagnosis of a spontaneous rupture of extensor tendons in the left thigh. 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 recording of diseases and health conditions. The code specifically indicates that the rupture of the extensor tendons, which are responsible for extending or straightening the leg at the knee joint, occurred without any external trauma or injury, and it is localized to the left thigh. This information is crucial for healthcare providers in managing treatment plans, facilitating communication with insurance companies for billing purposes, and maintaining accurate patient records.

When to use the ICD code for spontaneous rupture of extensor tendons in the left thigh, consider the following diagnostic criteria and symptoms:

1. Patient History
- Recent history of trauma or injury to the left thigh.
- Previous tendon injuries or surgeries in the same area.

2. Physical Examination Findings
- Visible deformity or abnormal positioning of the left thigh.
- Swelling or bruising around the knee or thigh region.

3. Pain Assessment
- Severe pain localized to the left thigh, particularly during movement.
- Pain that worsens with extension or flexion of the knee.

4. Functional Limitations
- Inability to extend the knee or perform normal range of motion.
- Difficulty in weight-bearing activities or ambulation.

5. Imaging Studies
- MRI or ultrasound confirming the rupture of extensor tendons.
- X-rays to rule out associated fractures or other injuries.

6. Symptoms of Complications
- Signs of infection such as fever, redness, or increased swelling.
- Neurological symptoms like numbness or tingling in the lower limb.

7. Response to Conservative Treatment
- Lack of improvement with rest, ice, compression, and elevation (RICE).
- Persistent symptoms despite physical therapy interventions.

These criteria should guide healthcare providers in determining the appropriate use of the ICD code for this specific condition.

For the ICD code M66.252, which pertains to the spontaneous rupture of extensor tendons in the left thigh, the relevant CPT codes that may be applicable for treatment include:

1. 27385 - Suture of infrapatellar tendon.

2. 27386 - Suture of quadriceps or hamstring muscle rupture; primary.

3. 27387 - Suture of quadriceps or hamstring muscle rupture; secondary.

4. 27650 - Repair, primary, open or percutaneous, of ruptured Achilles tendon.

5. 27652 - Repair, primary, open or percutaneous, with graft, of ruptured Achilles tendon.

6. 27654 - Repair, secondary, Achilles tendon, with or without graft.

These CPT codes are examples of procedures that might be considered for addressing tendon ruptures, depending on the specific clinical scenario and the healthcare provider's treatment plan. Always consult with a coding specialist or refer to the latest CPT coding guidelines for the most accurate coding practices.
