Lobsang Sherpa, 22, a member of a team guiding a commercial expedition up the 8,848-metre mountain, was returning to the team's campsite when he fell, said Mingma Sherpa of climbing agency Seven Summits Treks.
"He was returning from the height of 8,000 metres after hauling the tents for an 11-member Chinese expedition team," he said, adding that the body had been recovered and was being airlifted to Kathmandu.
Two other climbers have died on the world's highest peak this season.
Last season, six climbers died on Everest, making it one of the deadliest years in recent memory and sparking a debate about whether overcrowding was contributing to the death toll.
More than 3,000 people have climbed Everest and approximately 300 have perished since it was first conquered by Edmund Hillary and Tenzing Norgay in 1953. Every year hundreds more set out in April to attempt the climb.
