ICD Code M66.352

ICD code M66.352 is used to classify and document a medical diagnosis of a spontaneous rupture of the flexor tendons in the left thigh. This condition involves the sudden tearing or breaking of the tendons responsible for bending or flexing the leg at the knee joint, without any apparent external trauma or injury. Such ruptures can occur due to underlying conditions that weaken the tendons, such as degenerative diseases or chronic overuse. Proper coding of this condition is crucial for accurate medical records, billing, and insurance claims processing within the healthcare revenue cycle.

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

1. Patient History:
- Recent trauma or injury to the left thigh.
- History of repetitive strain or overuse of the left thigh muscles.

2. Clinical Symptoms:
- Sudden onset of pain in the left thigh.
- Swelling or bruising in the area of the left thigh.
- Limited range of motion in the left leg.

3. Physical Examination Findings:
- Tenderness upon palpation of the left thigh.
- Palpable defect or gap in the tendon area.
- Weakness in flexion of the left knee or hip.

4. Imaging Studies:
- MRI or ultrasound confirming the rupture of flexor tendons in the left thigh.
- X-rays to rule out associated fractures or other injuries.

5. Functional Impairment:
- Difficulty performing activities that require flexion of the left leg.
- Inability to bear weight on the left leg without pain.

6. Exclusion of Other Conditions:
- Ruling out other causes of thigh pain, such as muscle tears, ligament injuries, or vascular issues.

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

For the ICD code M66.352, which pertains to the spontaneous rupture of flexor tendons in the left thigh, the relevant CPT codes that may be applicable for treatment could 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 (delayed).

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 depending on the specific clinical scenario and the healthcare provider's assessment. It's important for healthcare providers to select the most appropriate CPT code based on the specific details of the patient's condition and the treatment provided.
