Osteitis condensans, unspecified shoulder

This code represents a non-inflammatory sclerosis or condensation of bone, specifically affecting an unspecified shoulder. It is characterized by increased bone density, often appearing as a localized area of increased radiodensity on imaging studies, without evidence of infection or tumor.

Use this code when documentation indicates osteitis condensans affecting the shoulder, and the laterality (left or right) is not specified. This diagnosis is typically supported by radiographic findings showing increased bone density in the glenohumeral joint or surrounding structures, in the absence of other pathological processes.

• Ensure documentation explicitly states "unspecified shoulder" or lacks laterality for accurate coding.
• Differentiate from osteomyelitis (M86.-) which involves bone infection.
• Consider additional codes for any associated symptoms or underlying conditions, if documented.
