Experts have warned an array of problems persists at the National Social Security Fund (NSSF) that risks the collapse of the country's major health care and social protection system, The Daily Star has reported. "The persisting conflict between the NSSF, [private] hospitals and the doctors' associations risk health care and social benefits in Lebanon," said the secretary-general of the Lebanese Order of Physicians, Sami Rayshouni. A major reason behind financial problems at the NSSF was the continuous delays by the government in paying its 25% share of the fund's budget, said the financial director of the NSSF, Sami Youssef. "The government is also responsible for the payment of subscription fees for employees in public administrations and institutions," he said. Some experts estimate the government owes the NSSF in excess of $500m in arrears, the report said.
