Nontraumatic ischemic infarction of muscle, right shoulder

This code signifies muscle tissue death in the right shoulder due to a lack of blood supply, not caused by trauma. This ischemic event leads to cellular damage and necrosis within the muscle fibers. The condition is characterized by acute onset of pain and dysfunction in the affected shoulder.

Apply this code when documentation explicitly states a nontraumatic ischemic infarction of the right shoulder muscle. This typically occurs in patients with underlying vascular disease or conditions leading to compromised blood flow. Supporting documentation should include imaging findings (e.g., MRI) confirming muscle infarction and a clear absence of traumatic injury.

• Differentiate from muscle strains or tears, which are traumatic in nature.
• Ensure the documentation specifies "nontraumatic" and "ischemic infarction" to avoid miscoding.
• Always verify the laterality (right shoulder) is clearly documented.
