ICD Code M67.362

ICD code M67.362 is used to identify the medical condition known as transient synovitis of the left knee. This condition is characterized by temporary inflammation of the synovium, which is the lining of the joint. It typically results in pain and swelling in the knee, often affecting mobility. The term "transient" indicates that the condition is temporary and usually resolves on its own, although it may require medical attention to manage symptoms and ensure proper recovery. This code is part of the International Classification of Diseases (ICD) system, which is used by healthcare providers to standardize the diagnosis and billing processes.

When to use the ICD code for transient synovitis of the left knee, consider the following diagnostic criteria and symptoms:

1. Acute Onset of Symptoms: The patient presents with a sudden onset of knee pain, typically following a minor injury or without a clear cause.

2. Localized Swelling: Noticeable swelling around the left knee joint, which may be accompanied by warmth and tenderness.

3. Limited Range of Motion: The patient exhibits restricted movement in the left knee due to pain and swelling.

4. Pain on Movement: Increased pain during activities that involve bending or bearing weight on the affected knee.

5. Absence of Fever: The patient does not present with systemic signs of infection, such as fever or chills.

6. Normal Laboratory Results: Blood tests show no significant signs of infection or inflammatory markers, ruling out septic arthritis.

7. Imaging Findings: X-rays or ultrasound may reveal joint effusion but typically show no significant bony abnormalities.

8. Age Consideration: The patient is usually a child or adolescent, as transient synovitis is more common in this demographic.

9. Exclusion of Other Conditions: Other potential causes of knee pain, such as septic arthritis, osteomyelitis, or trauma, have been ruled out through clinical evaluation and diagnostic testing.

These criteria should guide healthcare providers in determining the appropriate use of the ICD code for transient synovitis of the left knee.
