Infective myositis, right shoulder

This code signifies an inflammatory condition of the skeletal muscle in the right shoulder, specifically caused by an infectious agent. It indicates the presence of an infection directly affecting the muscle tissue, leading to pain, swelling, and impaired function in the specified anatomical area.

Apply this code when documentation clearly states a diagnosis of myositis of the right shoulder due to an identified or presumed infection. This includes bacterial, viral, fungal, or parasitic causes impacting the muscle. Supporting documentation should include physician notes detailing the infectious etiology and the specific anatomical site.

• Ensure the documentation specifies "infective" myositis; otherwise, consider non-infective myositis codes.
• Verify the laterality (right shoulder) is explicitly stated. If unspecified, an unspecified laterality code would be more appropriate.
• Always sequence an additional code to identify the specific infectious organism, if known and documented.
