Osteopathy in diseases classified elsewhere, unsp site

This code signifies a bone disorder or condition that is a manifestation or complication of another underlying disease process, where the specific anatomical location of the osteopathy is not documented. It indicates a secondary bone involvement rather than a primary bone disease.

Use this code when documentation clearly links an osteopathic condition to an underlying systemic disease (e.g., endocrine disorders, metabolic conditions, or certain infections), but the specific bone or joint affected is not specified. This code is appropriate when the primary disease is coded separately.

• Always sequence the underlying disease first, as this code represents a manifestation.
• Avoid using this code if a more specific code for the osteopathy (e.g., M90.81-M90.89 for specific sites) is available and documented.
• Query the provider for a more specific site if possible to avoid using an unspecified code.
