Development On April 3, 2025,
ABC renewed the series for a twenty-second season with Meg Marinis' third year as
showrunner. The season consists of 18 episodes, consistent with the episode order of Season 21. It surpassed the 450 episode mark during episode 2, extending its record as the longest-running American primetime medical drama. Filming began on August 1. Season 22 premiered in the United States on October 9, 2025.
Casting Ellen Pompeo will continue to narrate the series and receive star billing, appearing in seven episodes, as she did in Season 21.
Chandra Wilson and
James Pickens Jr. remain the only original cast members confirmed to appear in all 18 episodes. On October 9, 2025,
Trevor Jackson, who guest starred as Dr. Wes Bryant in the last two episodes of
Season 21, was promoted to a series regular. Continuing from last season, the minimum episode guarantee for most series regulars was reduced to 14 out of 18 episodes. However, longtime cast member
Caterina Scorsone's role was further scaled back, resulting in a total of 11 appearances for the season. Following her character's sabbatical in episode two, Scorsone was absent for seven episodes, returning for episode 10 in January 2026. In November 2025, James Pickens Jr. opened up about his
prostate cancer diagnosis, which now mirrors the storyline of his character
Dr. Richard Webber, who revealed he has cancer in the mid-season finale. Subsequently, he announced being cancer-free. In December 2025, it was revealed that
Kate Walsh will reprise her role as Dr. Addison Montgomery in episode 10, titled "
Strip That Down", airing January 29, 2026. The guest appearance was a nod to Sigler's real life MS condition and was also deemed a way of showing her real life condition openly to a television audience. On March 25, 2026, it was announced that series regulars
Kevin McKidd (
Dr. Owen Hunt) and
Kim Raver (
Dr. Teddy Altman) will depart the series after the season finale.{{Cite web |last=Andreeva|first=Nellie | date=March 25, 2026|title= ‘Grey’s Anatomy’ Shocker: Kim Raver & Kevin McKidd Leaving; Creator Shonda Rhimes Teases “Happy Ending” For Teddy & Owen == Future ==
