Nontraumatic ischemic infarction of muscle, unsp shoulder

This code signifies the death of muscle tissue in an unspecified shoulder due to a lack of blood supply, not caused by an injury. This condition, also known as muscle infarction or rhabdomyolysis, results from ischemia leading to myonecrosis.

Use this code when documentation clearly indicates a diagnosis of nontraumatic ischemic infarction affecting the shoulder musculature, and the specific shoulder (left or right) is not specified. This typically occurs in patients with underlying vascular compromise or conditions predisposing to muscle ischemia.

• Ensure documentation explicitly states "nontraumatic" and "ischemic infarction" of muscle.
• Avoid using this code if the specific shoulder (left or right) is documented; instead, use the more specific M62.211 or M62.212.
• Consider sequencing this code after a code for the underlying cause of the ischemia, if known and documented.
