Malignant hyperthermia due to anesthesia, initial encounter

This code signifies a life-threatening, inherited disorder characterized by a rapid and severe rise in body temperature, muscle rigidity, and metabolic acidosis, triggered by exposure to certain anesthetic agents. It represents the initial presentation and management of this acute hypermetabolic crisis.

Apply this code when documenting the first instance of a patient experiencing malignant hyperthermia as a direct adverse reaction to anesthesia. This includes cases identified during or immediately following a surgical procedure where anesthetic agents were administered.

• Ensure documentation clearly links the hyperthermia to anesthetic exposure.
• Confirm this is the patient's first documented episode of malignant hyperthermia.
• Consider additional codes for specific anesthetic agents or other complications, if applicable.
