ICD Code M61.112

ICD code M61.112 is used to identify the condition known as myositis ossificans progressiva affecting the left shoulder. This condition involves the abnormal development of bone tissue within muscle, leading to stiffness and restricted movement in the affected area. The code specifically indicates that the ossification is occurring in the left shoulder, which is crucial for accurate diagnosis, treatment planning, and billing purposes within the healthcare revenue cycle.

When considering the use of the ICD code for Myositis ossificans progressiva, left shoulder, the following diagnostic criteria and symptoms should be evaluated:

1. Clinical History

2. Physical Examination
