The 55-year-old actor took to Twitter to share a selfie taken on his way home from hospital on February 6.
"This was taken last Friday when I was released from the hospital and on my way home. Freedom!," he wrote.
Kilmer looked healthy in the photo as he smiled widely at the camera. He wore a grey Nike hoodie and his neck was covered amid rumors that he underwent a surgery for a throat tumor.
Kilmer was rushed to UCLA Medical Center in Santa Monica after he allegedly began bleeding from the throat last month.
