The 47-year-old actress' husband, actor Kevin Bacon, posted pictures of his wife on his WhoSay account June 29 after the incident, which occurred while she was chopping greens.
In one picture, Sedgwick looked glum on a hospital bed with her finger wrapped in bloody bandages.
Under the emergency room picture, Bacon wrote "Kale isn't always healthy if you chop the end of your finger off."
The second photo shows her giving a thumbs-up sign once back at home. In the caption, Bacon wrote "My baby is fine. All good. Still can't find the tip of that finger."
