The diagnosis codes for SJS-TEN overlap are L51.3 (Toxic epidermal necrolysis [Lyell]) and T50.4x5A (Adverse effect of other and unspecified drugs, medicaments and biological substances, initial encounter). The code L49.3 (Acquired ichthyosis) represents the skin peeling off. The patient's recent use of allopurinol for gout supports the suspicion that it is the cause of the reaction. Therefore, the code M10.9 (Gout, unspecified) can be added.
