The LOL star injured herself while cooking on Monday and sought treatment at a Los Angeles hospital.
"[She] cut her finger while cooking. [She] had to get a few stitches. She's doing fine," a rep for Cyrus told People.
The 19-year-old, who was photographed leaving the medical facility, was said to be "experiencing a little bit of discomfort, but tear-free".
Cyrus recently responded to rumours that she is suffering from anorexia, insisting that she is healthy, but suffers from a gluten and lactose allergy.
She co-stars with Demi Moore in LOL, which opens on limited release in the US on May 4 and in the UK in June.
