Cigna has appointed Phil Austin as managing director of its healthcare benefits business in the UK.
The announcement follows the resignation of James Parker from the role earlier in 2015.
Austin joined Cigna in 2002 as partnership director for the UK business and has since worked in international roles for the insurer.
His new role will be based in Glasgow, and his former role at Cigna's Global IPMI business will be taken by Arjan Toor.
Toor will be moving to the UK from Hong Kong where he was chief marketing officer of Cigna's international division.
Austin said: "I'm delighted to be re-joining Cigna's UK HealthCare Benefits business at a time when the demand for health benefits is growing.
"There's no doubt that private healthcare has a bigger role to play in the overall UK healthcare system.
"And it's our job as an insurer to provide benefit plans that make it easy for employees to access care whilst producing a measurable return for employers."
