ICD Code M60.021

ICD code M60.021 is used to identify a medical condition known as infective myositis of the right upper arm. This condition refers to an infection that causes inflammation of the muscles in the right upper arm. It can result from bacterial, viral, or other microbial infections and typically presents with symptoms such as pain, swelling, and reduced mobility in the affected area. Proper diagnosis and treatment are essential to manage the infection and prevent further complications.

When to use the ICD code for Infective Myositis, Right Upper Arm:

1. Presence of Symptoms:
- Localized pain in the right upper arm
- Swelling or edema in the affected area
- Muscle tenderness or soreness

2. Clinical Findings:
- Evidence of muscle weakness in the right upper arm
- Palpable warmth or erythema over the affected muscle
- Limited range of motion in the right shoulder or arm

3. Laboratory Tests:
- Elevated creatine kinase (CK) levels indicating muscle damage
- Positive results for infectious agents (e.g., bacteria, viruses) in blood or muscle biopsy
- Elevated inflammatory markers (e.g., C-reactive protein, erythrocyte sedimentation rate)

4. Imaging Studies:
- MRI or ultrasound showing inflammation or edema in the right upper arm muscles
- Abscess formation or other structural abnormalities in imaging results

5. Patient History:
- Recent history of infection or systemic illness
- Previous trauma or injury to the right upper arm
- Immunocompromised status or underlying chronic conditions

6. Differential Diagnosis:
- Exclusion of other causes of muscle pain or inflammation (e.g., autoimmune myositis, trauma, or other infections)

7. Response to Treatment:
- Monitoring of symptoms and clinical findings following initiation of antibiotic or antiviral therapy
- Improvement or worsening of symptoms correlating with treatment efficacy
