Other specified disorders of bone, upper arm

This code signifies a bone disorder affecting the upper arm that is not otherwise classified or specified by a more precise ICD-10-CM code. It encompasses various non-traumatic, non-infectious, and non-neoplastic conditions impacting the humerus or associated structures, such as osteonecrosis not elsewhere classified, stress fractures, or other metabolic bone diseases localized to the upper arm.

Apply this code when documentation clearly indicates a specific, but uncommon, disorder of the humerus or upper arm bone that doesn't have a dedicated code. This is appropriate for conditions like localized osteopenia, bone cysts, or other structural anomalies of the upper arm bone that are not congenital, traumatic, or inflammatory in nature. Ensure the medical record explicitly states "other specified" or provides a diagnosis that falls into this residual category.

• Always attempt to find a more specific code before resorting to this "other specified" category.
• Ensure the documentation clearly identifies the disorder as affecting the "upper arm" to justify the 7th character '2'.
• Do not use this code for unspecified bone disorders; use the appropriate "unspecified" code if the specific condition is not documented.
