Erythroderma (widespread skin inflammation)

VA rates erythroderma under Diagnostic Code 7817. The rating reflects two main factors: how widespread the skin involvement is and whether it causes systemic effects such as fever, weight loss, or low protein levels, combined with what kind of treatment you have needed over the past 12 months.

A 100% rating applies when the skin involvement is generalized and accompanied by systemic manifestations, and you have required constant or near-constant systemic therapy over the past 12 months, or you have no current treatment because two or more treatment regimens have failed. A 60% rating applies when the skin involvement is generalized but without systemic manifestations, and you have required constant or near-constant systemic therapy, or one treatment regimen has failed. A 30% rating applies when systemic therapy has been needed for a total of 6 weeks or more, but not constantly, over the past 12 months, regardless of how much skin is involved. A 10% rating applies when systemic therapy was needed for less than 6 weeks over the past 12 months. A 0% rating applies when only topical therapy has been needed. Treatment failure means disease progression or less than a 25% reduction in extent and severity after four weeks of prescribed therapy, as documented by medical records.
