Other hypertrophic osteoarthropathy, unspecified shoulder

This code identifies a hypertrophic osteoarthropathy affecting an unspecified shoulder joint, where the specific type of hypertrophic osteoarthropathy is not documented. This condition involves abnormal bone and joint changes, often associated with underlying systemic diseases. It typically presents with pain, swelling, and clubbing of digits.

Use this code when documentation indicates hypertrophic osteoarthropathy of the shoulder, but the physician has not specified the exact type (e.g., primary, secondary, pachydermoperiostosis). This code is appropriate when the laterality of the shoulder is also not specified in the medical record. Supporting documentation should describe the characteristic bone and joint changes consistent with hypertrophic osteoarthropathy.

• Always seek clarification from the provider if the specific type of hypertrophic osteoarthropathy or laterality of the shoulder is not documented.
• Do not use this code if a more specific type of hypertrophic osteoarthropathy (e.g., M89.40, M89.411, M89.412) or laterality is known.
• Code any underlying systemic condition (e.g., lung cancer, inflammatory bowel disease) as a primary diagnosis if it is the cause of the secondary hypertrophic osteoarthropathy.
