On Tuesday, the Los Angeles County Department of Medical Examiner-Coroner said Boyce's cause of death had been determined, calling it a "sudden unexpected death in epilepsy".
A post-mortem was carried out on July 8 but further testing was needed to establish the cause of death.
His manner of death was "natural", the coroner said.
Boyce was born in California and was also known for his humanitarian work.
He played Luke Ross in Jessie, and Carlos in Descendants, the TV movie series.
Appearing on screen from a young age, his other credits included Mirrors, Eagle Eye, and Grown Ups and Grown Ups 2.
Following his death, co-stars including Dove Cameron, Adam Sandler, Salma Hayek and Debby Ryan paid tribute, while his family said they were "utterly heartbroken".
