In a statement released over the weekend, they said he had a "minor outpatient procedure" at Denver's Rose Medical Center and was "doing well".
The 58-year-old, who is currently headlining the annual Ozzfest tour, is now out of hospital.
He is currently in Missouri, where he is scheduled to perform.
The star, who rose to fame in the 1970s as lead singer with heavy metal group Black Sabbath, is currently headlining the annual Ozzfest tour.
Earlier this month, he became the first artist to be honoured on the Hollywood-style Walk of Fame in his home city of Birmingham.
Osbourne's health has suffered over the years. After battling drug and alcohol abuse, he nearly died in December 2003 following a quad bike accident.
Osbourne's daughter Kelly, 22, is to make her West End debut in the musical Chicago as prison matron Mama Morton.
She will be the youngest actress to take on the role, which has also been played by singers Alison Moyet in the stage production and Queen Latifah in the film.
She came to fame through her family's reality TV show on MTV, The Osbournes, and joins the cast at London's Cambridge Theatre for a seven-week season from 10 September.
