Skin thickening disorders

Medical records that document the percentage of your body surface or exposed areas affected by characteristic lesions are central to this rating. A dermatologist's examination notes that estimate or measure affected skin area — whether on your entire body or on areas typically visible, such as your face, hands, and arms — directly support the body-surface criteria at each level.

Treatment records are equally important. For the 60% level, records showing that systemic therapy such as oral corticosteroids, retinoids, biologics, phototherapy, PUVA, or other immunosuppressive drugs was required constantly or near-constantly over the past 12 months carry significant weight. For the 30% level, pharmacy records, prescription histories, or clinic notes showing at least 6 cumulative weeks of such therapy — though not constant — over the past 12 months support that tier. For the 10% level, similar records showing less than 6 total weeks of intermittent systemic therapy are relevant.

Statements from you or people who know you that describe how your skin condition affects your daily activities — such as limitations in exposure to sunlight, difficulties with physical tasks, or the time burden of treatment — can help show the ongoing nature and severity of your condition alongside the clinical records.
