Kimmel thanked doctors, nurses and therapists at Children’s Hospital Los Angeles and Cedars-Sinai, saying Billy is doing well thanks to their care. He also encouraged supporters to donate $9 to CHLA through the link in his bio, using #CatchAndRelease to boost the appeal.
Billy, born in 2017 with congenital heart disease, has undergone at least three open‑heart surgeries. Over the years Kimmel has publicly shared updates and praised the hospitals and his wife Molly McNearney for their strength as the family navigated the treatments.
