713.3
ICD-9-CMThis code signifies joint disease (arthropathy) that is directly linked to or a complication of a dermatological condition. It describes inflammatory or degenerative joint changes occurring in conjunction with skin disorders, where the skin condition is considered the primary etiology for the joint involvement.
Apply this code when documentation clearly indicates a causal relationship between a skin disorder and the patient's arthropathy. This is appropriate for conditions like psoriatic arthritis, arthropathy associated with erythema nodosum, or other connective tissue diseases with prominent dermatological manifestations affecting the joints.
