Other hypertrophic osteoarthropathy, right shoulder

This code signifies a non-specific overgrowth of bone and soft tissue in the right shoulder joint, not due to primary or secondary hypertrophic osteoarthropathy. It indicates a localized, abnormal enlargement of the bone and cartilage structures within the shoulder.

Apply this code when documentation specifies hypertrophic osteoarthropathy affecting the right shoulder, but without a definitive diagnosis of primary (e.g., pachydermoperiostosis) or secondary (e.g., associated with lung cancer) forms. This code is appropriate when the hypertrophy is localized to the shoulder and the underlying cause is not fully elucidated or does not fit other specific categories.

• Ensure the documentation clearly specifies "right shoulder" to avoid laterality errors.
• Do not use this code if a more specific type of hypertrophic osteoarthropathy (e.g., primary or secondary) is diagnosed; use the appropriate subcategory instead.
• Code any underlying conditions or associated symptoms separately, if documented.
