Other general diseases with articular involvement

This code represents systemic diseases that manifest with joint pain, inflammation, or other articular involvement, but are not specifically classified elsewhere. It covers a broad range of conditions where the joints are affected as part of a more generalized disease process. This includes conditions like sarcoidosis, amyloidosis, or metabolic disorders with secondary arthropathy.

Use this code when documentation indicates articular involvement secondary to a systemic disease that doesn't have a more specific ICD-9-CM code for its arthropathy. This code is appropriate when the physician explicitly links the joint symptoms to an underlying general disease. Supporting documentation should clearly identify both the systemic disease and the associated joint manifestations.

• Always code the underlying systemic disease first, followed by this code to indicate the articular involvement.
• Avoid using this code if a more specific code exists for the arthropathy associated with a particular systemic disease (e.g., arthropathy in psoriasis).
• Ensure the medical record clearly establishes a causal link between the general disease and the articular symptoms; do not assume a connection.
