Bupa has been named as the official health insurance partner of UK Sport for the next two years, including the London Olympics.
The provider has supported the Athlete Medical Scheme (AMS) for nine years before making the commercial agreement alongside BAE Systems, British Airways and Maxinutrition.
UK Sport's AMS, delivered in partnership with the English Institute of Sport, provides over 1200 of the UK's best athletes on the World Class Performance Programme with specialist medical treatment, when expertise outside of the day to day medical support is required.
This varies from diagnostic tests and MRI scans to surgical procedures.
Liz Nicholl, chief executive of UK Sport, said she was delighted with the agreement, and added: "Providing world class medical support to our top athletes is of paramount importance.
"Early identification, treatment and recovery are all critical in allowing them to compete at the very highest level and prolong their careers."
Natalie-Jane Macdonald, managing director of Bupa Health and Wellbeing, said: "We're very proud of our record over the past nine years in providing Britain's athletes with access to an even wider pool of medical expertise.
"Our partnership with UK Sport means we can continue to provide access to this essential support - ensuring that when our athletes do get injured they're back competing at their very best as soon as possible."
