Myalgia, other site

This code signifies muscle pain that is not localized to the head, neck, trunk, upper limb, or lower limb. It describes generalized or diffuse muscle aches and pains affecting areas not specified by more granular myalgia codes.

Use this code when the medical record documents myalgia in a location not otherwise specified, or when the pain is widespread and does not fit a more specific anatomical site. Documentation should clearly state "myalgia, other site," "generalized myalgia," or "diffuse muscle pain" without further localization.

• Do not use this code if a more specific anatomical site for the myalgia is documented (e.g., M79.10 for unspecified site, M79.11-M79.17 for specific sites).
• Always review documentation for underlying causes of myalgia (e.g., influenza, fibromyalgia) as these may require additional coding.
• This code is often used when the provider cannot pinpoint a specific muscle group or region for the pain.
