Osteolysis, right upper arm

This code signifies the pathological destruction or dissolution of bone tissue in the right upper arm. It indicates a process where bone matrix is being resorbed, leading to bone loss and potential structural weakening. This can be a localized or generalized process affecting the humerus.

Apply this code when documentation explicitly states osteolysis affecting the right upper arm, such as in cases of tumor-induced bone destruction, inflammatory conditions, or metabolic bone diseases. Supporting documentation should include imaging reports (X-ray, MRI, CT) confirming bone resorption in the specified anatomical location, along with a physician's diagnostic statement.

• Ensure laterality is clearly documented (right upper arm).
• Investigate the underlying cause of the osteolysis; a more specific code for the primary condition should be sequenced first, if known.
• Distinguish from osteopenia or osteoporosis, which represent decreased bone density rather than active bone destruction.
