Dress syndrome is classified under the ICD-9 code 695.11, which refers to drug reaction with eosinophilia and systemic symptoms. This condition is characterized by fever, rash, lymphadenopathy, and internal organ involvement following exposure to certain medications. It is important to note that ICD-9 has been largely replaced by ICD-10 coding, so for current coding practices, you may want to refer to the ICD-10 equivalent.
