Coxsey was appointed Member of the Order of the British Empire (MBE) in the 2016 Birthday Honours for services to climbing.[9][20][21] In late 2016, she suffered a shoulder injury which prevented her from competing in that year's Bouldering World Championships,[11] despite topping the overall rankings in the Bouldering World Cup.[22] She won four IFSC Climbing World Cups in Meiringen (SUI), Kazo (JPN), Innsbruck (AUT) and Sheffield (UK). At the World Cup in Munich (GER) she placed second.[10] In 2017, she again won four Bouldering World Cup stages,[11] in Meiringen (SUI), Kazo (JPN), Mumbai (IND) and Vail (USA). In Munich (GER) she again placed second and secured the overall 2017 title.[3][10] In August 2019, she won two bronze medals at the 2019 IFSC Climbing World Championships in Hachioji, in bouldering and the combined event. During the finals of the combined event, she set a British women's speed climbing record of 9.141 seconds, securing second place in the speed component of the combined ranking by winning races against Futaba Ito and Miho Nonaka before losing to Aleksandra Miroslaw. Additionally, by reaching the finals of the combined event, she secured a qualification spot for Tokyo's 2020 Summer Olympics, the first to include competitive climbing.[23] When the Olympics was finally in 2021, she was recovering from a back injury, surgical treatment and rehabilitation. She came 10th in the competition. She planned to discontinue competitive climbing after the Olympics, but to continue as an elite-level rock climber.[24]
In 2022 she continued climbing on indoor climbing walls while pregnant with her first child. She worked with a specialist physiotherapist, and her husband who is also a climber, to assess the routes as her shape changed.[24]
