ICD Code M66.142

ICD code M66.142 is used to identify a medical condition characterized by the rupture of the synovium in the left hand. The synovium is a specialized connective tissue that lines the inner surface of capsules of synovial joints and tendon sheaths, producing synovial fluid for lubrication. A rupture in this area can lead to pain, swelling, and impaired function of the hand, potentially affecting a patient's ability to perform daily activities. This code is utilized by healthcare providers for accurate documentation, billing, and communication regarding the patient's diagnosis and treatment plan.

When to use the ICD code for a rupture of synovium in the left hand, consider the following diagnostic criteria and symptoms:

1. Clinical Presentation
- Patient reports acute pain in the left hand.
- Swelling or inflammation observed in the affected area.

2. Physical Examination Findings
- Tenderness upon palpation of the left hand.
- Limited range of motion in the affected joints.

3. Imaging Studies
- MRI or ultrasound shows evidence of synovial rupture.
- X-rays may rule out fractures or other bone-related issues.

4. History of Trauma
- Recent injury or trauma to the left hand, such as a fall or impact.
- Previous history of joint disorders or conditions affecting the synovium.

5. Associated Symptoms
- Presence of joint effusion or fluid accumulation in the left hand.
- Signs of infection, such as redness, warmth, or fever, if applicable.

6. Differential Diagnosis
- Exclusion of other conditions that may mimic symptoms, such as arthritis or tendon injuries.

7. Response to Treatment
- Lack of improvement with conservative management (e.g., rest, ice, elevation).
- Need for further intervention, such as aspiration or surgical evaluation.

These criteria should guide healthcare providers in determining the appropriate use of the ICD code for documenting the diagnosis accurately.
