Other myositis, right shoulder

This code signifies inflammation of the muscle tissue in the patient's right shoulder, not otherwise specified as infectious, interstitial, or due to another classified cause. It encompasses various forms of myositis affecting this specific anatomical site that don't fit more precise diagnostic categories.

Apply this code when documentation clearly indicates myositis of the right shoulder, and no more specific ICD-10-CM code (e.g., infectious myositis, dermatomyositis, polymyositis) is applicable. This code is appropriate when the provider's diagnosis explicitly states "other myositis" or "myositis, NOS" localized to the right shoulder.

• Ensure laterality is explicitly documented as "right shoulder" to support this specific code.
• Distinguish from M60.812 (left shoulder) and M60.819 (unspecified shoulder) based on provider documentation.
• Always review for more specific myositis codes (e.g., M33.- for inflammatory myopathies) before assigning this "other" category.
