Arthropathies in oth diseases classd elswhr, multiple sites

This diagnosis code signifies joint diseases (arthropathies) that are a manifestation of, or associated with, other specific underlying systemic conditions, affecting multiple anatomical sites. It indicates that the joint involvement is secondary to another disease process, rather than a primary joint disorder.

Apply this code when documentation clearly links polyarticular arthropathy to an underlying systemic disease not otherwise specified in more specific M14 subcategories (e.g., M14.0 for gouty arthropathy, M14.1 for crystal arthropathy). Examples include arthropathy associated with metabolic disorders, hematological disorders, or other systemic conditions affecting multiple joints. The medical record must specify the underlying disease.

• Always sequence the underlying systemic disease code first, as this code represents a manifestation.
• Ensure documentation specifies "multiple sites" of arthropathy; otherwise, consider a more specific single-site code if applicable.
• Do not use this code if a more specific M14 subcategory exists for the documented underlying disease (e.g., arthropathy in sarcoidosis has a dedicated code).
