ICD Code M67.242

ICD code M67.242 is used to identify a medical condition known as synovial hypertrophy, not elsewhere classified, specifically affecting the left hand. Synovial hypertrophy refers to the abnormal enlargement or thickening of the synovial membrane, which is the lining of the joints. This condition can lead to joint pain, swelling, and reduced mobility. The code is part of the International Classification of Diseases (ICD) system, which is used by healthcare providers to standardize diagnoses and facilitate billing and insurance processes. By specifying "not elsewhere classified," the code indicates that the condition does not fit into other more specific categories within the ICD system.

When to use the ICD code for synovial hypertrophy, not elsewhere classified, left hand:

1. Presence of Synovial Hypertrophy
- Documented swelling or thickening of the synovial membrane in the left hand.

2. Location Specification
- Symptoms specifically affecting the left hand, with no involvement of the right hand or other joints.

3. Exclusion of Other Diagnoses
- Confirmation that the synovial hypertrophy is not attributable to other classified conditions or diseases affecting the joints.

4. Duration of Symptoms
- Symptoms persisting for a significant period, indicating a chronic condition rather than an acute injury.

5. Associated Symptoms
- Presence of joint pain, stiffness, or limited range of motion in the left hand.

6. Diagnostic Imaging or Tests
- Results from imaging studies (e.g., MRI, ultrasound) indicating synovial thickening without other identifiable causes.

7. Clinical Evaluation
- Findings from a physical examination that support the diagnosis of synovial hypertrophy, such as tenderness or warmth in the affected area.

8. Response to Treatment
- Evaluation of treatment efficacy, where lack of improvement may further substantiate the diagnosis of synovial hypertrophy.

9. Documentation of Medical History
- Relevant past medical history that may contribute to the diagnosis, such as previous joint injuries or inflammatory conditions.

10. Referral to Specialist
- Involvement of a rheumatologist or orthopedic specialist for further evaluation and confirmation of the diagnosis.
