2021 ICD-10-CM Diagnosis Code T88.3
2021 ICD-10-CM Diagnosis Code T88.3
Malignant hyperthermia due to anesthesia
2016 2017 2018 2019 2020 2021 Non-Billable/Non-Specific Code
- T88.3 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
- The 2021 edition of ICD-10-CM T88.3 became effective on October 1, 2020.
- This is the American ICD-10-CM version of T88.3 - other international versions of ICD-10 T88.3 may differ.

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.

- A rare disorder characterized by rapid rise of the body temperature, accompanied by rhabdomyolysis and, if untreated, by collapse and death. It occurs in susceptible individuals who receive certain drugs for general anesthesia, gas anesthetics, or succinylcholine. It may be inherited in an autosomal dominant pattern.
- Rapid and excessive rise of temperature accompanied by muscular rigidity following general anesthesia.
- Usually inherited reaction to general anesthesia manifested as a sudden, rapid rise in temperature, hypermetabolism, and skeletal muscle rigidity; mutation is in the calcium release channel of skeletal muscle sarcoplasmic reticulum.
