Nearly 10,000 civil servants and those who had retired from service were treated in hospital in the first six months of the year after healthcare insurance for these groups came into effect.
The National Social Security Fund said it was registering with more state clinics and hospitals for civil servants to get free treatment.
NSSF director Ouk Sam Vichea said that up until now, the fund had registered 1,325 state hospitals and clinics to provide free healthcare services.
Civil servants who had not yet retired must bring their civil service ID card before getting free treatment. Those who have retired must show their retirement card.
Last year, King Norodom Sihamoni signed a decree establishing a social security healthcare fund for public officials, civil servants and those who had retired.
The edict covers more than 300,000 public servants, including those who work in ministries, institutions and national as well as sub-national units.
They get insurance that covers emergency treatment, pre- and post-natal care, illness consultation and many other services.
“The contribution of a social security fund for labour insurance for public officials is the duty of the state,” the decree says.
The measure also provides health insurance for veterans of the armed forces.
Labour Minister Ith Samheng said all public officials would have the same social security insurance.
The NSSF has set up the system for public officials to get the same services as workers in risky jobs.
Last year, the National Social Security Fund began registering local village officials and their constituents to create a health equity fund service from the government.
Village officials will be registered so they can begin facilitating free health care for villagers who can access Health Equity Fund cards.
Tep Prom Mony, Niroth commune chief, said village officials had already got health cards from the NSSF.
“It is very important for officials to get health insurance, too,” she said.
More than 8,000 businesses covering more than one million workers have registered with the NSSF.
