Answer :

Final answer:

The appropriate ICD-10-CM diagnosis codes for a patient undergoing open herniorrhaphy who has manifested malignant hyperthermia due to inhalation anesthesia are T88.3XXA and K40.90.

Explanation:

In the scenario provided, the patient undergoing an open herniorrhaphy has manifested malignant hyperthermia due to inhalation anesthesia. Malignant hyperthermia is a severe reaction to certain drugs used for anesthesia, which can be a life-threatening emergency. Accordingly, the appropriate ICD-10-CM diagnosis codes to document this situation would be:

  • T88.3XXA for Malignant hyperthermia due to anesthesia during surgery and other procedures, initial encounter.
  • K40.90 for Unilateral inguinal hernia, without obstruction or gangrene, not specified as recurrent, for the primary reason for the surgery, which is the herniorrhaphy.

Both codes are required to fully capture the clinical situation. The first code accounts for the reaction to the anesthesia, and the second code details the surgical procedure being performed.
