Mobb Deep star Prodigy died after choking on an egg.
The rapper - whose real name was Albert Johnson - passed away in hospital in Las Vegas in June, where he had been admitted after suffering complications with sickle cell anaemia.
Prodigy, 42, had suffered with the hereditary disease - in which red blood cells are distorted due to low oxygen levels in the blood - since birth, but the Clark County coroner's office has revealed that the star's illness played no part in his death.
TMZ reports that Prodigy's death has been listed as "accidental" after he choked on an egg.
The publicist for the 'Survival of the Fittest' hitmaker announced his death in a statement in June, saying: "It is with extreme sadness and disbelief that we confirm the death of our dear friend Albert Johnson, better known to millions of fans as Prodigy of legendary NY rap duo Mobb Deep. Prodigy was admitted to hospital a few days ago in Vegas after a Mobb Deep performance for complications caused by a sickle cell anaemia crisis. As most of his fans know, Prodigy battled the disease since birth. The exact causes of death have yet to be determined. We would like to thank everyone for respecting the family's privacy at this time."
The hip hop star - who was joined in Mobb Deep with his friend Havoc - was on tour in Las Vegas at the time of his death, following a performance as part of the 'Art of Rap' tour alongside the likes of Ghostface Killah, Onyx, KRS-One, and Ice-T.
Mobb Deep first broke out onto the music scene in the early 1990s, and has been hailed as "one of the most critically acclaimed hardcore East Coast Hip-Hop groups."
Alongside his work with Mobb Deep, Prodigy also had a solo career which he launched in 2000, and his last album 'Hegelian Dialectic', was released in January.
