ICD Code M61.145

ICD code M61.145 is used to identify the condition known as myositis ossificans progressiva affecting the left finger(s). Myositis ossificans progressiva is a rare disorder characterized by the abnormal development of bone tissue within muscles, tendons, and other soft tissues. This specific code indicates that the condition is localized to the fingers on the left hand, which can lead to stiffness, pain, and restricted movement in the affected area. Proper coding of this condition is crucial for accurate diagnosis, treatment planning, and reimbursement processes within the healthcare revenue cycle.

When to use the ICD code for Myositis Ossificans Progressiva, Left Finger(s):

1. Diagnosis Confirmation: The patient has been clinically diagnosed with myositis ossificans progressiva based on a thorough evaluation by a healthcare provider.

2. Symptoms Present:
- Progressive pain and swelling in the affected finger(s).
- Limited range of motion in the left finger(s).
- Presence of hard lumps or masses in the soft tissue of the left finger(s).

3. Imaging Studies: Radiological evidence (such as X-rays or MRIs) shows abnormal calcification or ossification in the soft tissues of the left finger(s).

4. Exclusion of Other Conditions: Other potential causes of similar symptoms (such as trauma, infection, or other inflammatory conditions) have been ruled out through appropriate diagnostic testing.

5. Family History: A documented family history of myositis ossificans progressiva or related connective tissue disorders may be present.

6. Age Consideration: The patient is typically within the age range where myositis ossificans progressiva is most commonly diagnosed, often in childhood or early adulthood.

7. Progressive Nature: The condition is characterized by a progressive course, with symptoms worsening over time rather than improving.

8. Clinical Evaluation: The healthcare provider has conducted a comprehensive clinical evaluation, including physical examination and assessment of functional limitations related to the left finger(s).

Using the ICD code is appropriate when these diagnostic criteria and symptoms are met, ensuring accurate documentation and billing for the condition.
