Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.

Clinical Information
  • A condition caused by the failure of body to dissipate heat in an excessively hot environment or during physical exertion in a hot environment. Contrast to heat exhaustion, the body temperature in heat stroke patient is dangerously high with red, hot skin accompanied by delusions; convulsions; or coma. It can be a life-threatening emergency and is most common in infants and the elderly.
  • Heat stroke caused by exposure to the sun. It is characterized by dangerously high body temperature; red, hot skin; delusions; convulsions; or coma. It can be a life-threatening emergency and is most common in infants and the elderly.
