Other psoriasis and similar disorders

This code represents various forms of psoriasis that do not fit into more specific categories, as well as other skin conditions that share clinical similarities with psoriasis. These conditions are characterized by chronic inflammation and epidermal hyperproliferation, often presenting with erythematous, scaly plaques.

Use this code for diagnoses such as inverse psoriasis, guttate psoriasis (when not acute), erythrodermic psoriasis, or psoriatic erythroderma. Documentation should clearly indicate a diagnosis of psoriasis that is not specified as plaque, arthropathic, or other distinct forms, or a similar chronic inflammatory skin disorder.

• Differentiate from more specific psoriasis codes (e.g., 696.0 for psoriatic arthropathy, 696.1 for other psoriasis).
• Ensure documentation specifies the type of psoriasis if not otherwise classifiable, or a psoriasis-like condition.
• Avoid using this code if a more precise ICD-9-CM code for a specific psoriasis variant is available.
