Maggie Lockwood, played by Marlyne Barrett, left Chicago Med because the actress needed to take a temporary leave from the show for personal reasons. The departure was not due to a storyline but rather to accommodate Barrett stepping back from the series. The show has left the door open for her return, and it is considered a temporary absence rather than a permanent exit. The season 11 premiere referenced Maggie's absence but did not explain the exact reasons for her departure within the storyline. Barrett's leave was announced in August 2025, and the showrunner expressed hope for her eventual return. Marlyne Barrett had been with Chicago Med since its debut and had a significant role as Charge Nurse Maggie Lockwood. Her temporary break aligns with her personal matters, and while there is no specific detailed explanation given publicly, fans have expressed concern and support due to her past health struggles, including a cancer diagnosis from which she is in remission. The show continues without her but retains the possibility of her character coming back in future episodes or seasons.
