The track was co-written and produced by Andrew Watt and features guitar from the talented Jeff Beck.
Speaking to Planet Radio, Ozzy said:
"The song is about a mental institution. Having someone like Jeff Beck play on my album is just incredible, a total honour. There's no other guitar player that plays like him and his solo on 'Patient Number 9' is just jaw-dropping."
