ICD Code M67.361

ICD code M67.361 is used to identify the medical condition known as transient synovitis of the right knee. This condition is characterized by temporary inflammation of the synovial membrane, which is the lining of the joint. It often results in pain and swelling in the affected knee, typically affecting children and adolescents. The "M67" part of the code refers to disorders of synovium and tendon, while the ".361" specifies the transient nature of the synovitis and its location in the right knee. This code is crucial for healthcare providers to accurately document and bill for the diagnosis and treatment of this condition.

When to use the ICD code for transient synovitis of the right knee:

1. Presence of Joint Pain
- Patient reports pain localized to the right knee.

2. Swelling of the Knee
- Observable swelling or effusion in the right knee joint.

3. Limited Range of Motion
- Difficulty in fully extending or flexing the right knee due to discomfort or mechanical blockage.

4. Recent History of Trauma or Infection
- Patient has a recent history of minor trauma to the knee or a preceding infection that may contribute to joint inflammation.

5. Age Consideration
- Typically occurs in children or adolescents, particularly those aged 3 to 10 years.

6. Exclusion of Other Conditions
- Differential diagnosis has ruled out other potential causes of knee pain and swelling, such as septic arthritis, osteomyelitis, or other inflammatory conditions.

7. Normal Laboratory Findings
- Blood tests show no significant signs of infection (e.g., normal white blood cell count) and inflammatory markers are within normal limits.

8. Imaging Results
- X-rays or MRI show no significant bony abnormalities or signs of joint degeneration, confirming the diagnosis of transient synovitis.

9. Response to Conservative Treatment
- Symptoms improve with rest, ice, and anti-inflammatory medications, indicating a transient condition rather than a chronic issue.
