Other polyosteoarthritis

This code signifies a chronic, degenerative joint disease affecting multiple joints throughout the body, but not meeting the specific criteria for generalized (M15.0) or primary erosive (M15.1) osteoarthritis. It indicates the presence of osteoarthritis in several distinct anatomical sites.

Apply this code when documentation specifies osteoarthritis affecting multiple joints, such as the hands, knees, and spine, without a clear designation of generalized or erosive forms. Supporting documentation should clearly list the affected joints and the diagnosis of osteoarthritis for each.

• Do not use this code if the documentation specifies "generalized osteoarthritis," which has its own dedicated code.
• Ensure the medical record clearly identifies multiple affected joints; otherwise, site-specific osteoarthritis codes may be more appropriate.
• Consider sequencing this code as a primary diagnosis if it is the main reason for the encounter, or as a secondary diagnosis if managing other conditions concurrently.
