Arthropathies in oth diseases classd elswhr, unsp site

This code signifies joint disease (arthropathy) that is a manifestation of another underlying, specified systemic disease, but where the specific joint affected is not documented. It indicates that the joint involvement is secondary to a primary condition classified elsewhere in the ICD-10-CM system.

Use this code when documentation clearly links an arthropathy to an underlying systemic disease (e.g., psoriatic arthropathy, enteropathic arthropathy, arthropathy due to sarcoidosis) but the specific joint(s) affected are not specified. This code is appropriate when the primary disease is known and coded separately.

• Always sequence the underlying systemic disease code first, followed by this code.
• Avoid using this code if a more specific code for the arthropathy (e.g., M07.- for psoriatic and enteropathic arthropathies) or a specific joint site is documented.
• Query the provider if the specific joint(s) affected by the arthropathy are not documented, to allow for more precise coding.
