His cause of death was previously speculated to be COVID-19 after he was hospitalized.
King died on January 23 in Los Angeles, California, at the age of 87.
Larry King's cause of death has been confirmed nearly one month after he died at age 87.
According to People, the legendary broadcaster's immediate cause of death was sepsis.
Sepsis occurs when " an infection you already have triggers a chain reaction throughout your body" and "is the body's extreme response to an infection," wrote the CDC.
The death certificate reportedly showed that King had two underlying conditions at the time, including hypoxic respiratory failure, which means there was not enough oxygen in his blood.
