Lawmakers approved on Friday the expenditure of Bulgaria's national health fund for next year.
Under the newly-adopted bill, health insurance contribution remains eight percent in 2015.
The National Health Insurance Fund (NZOK) will have more than BGN 3 B in spending, but will not be able to strike new contracts next year with hospitals becoming operational in 2015 or starting new activities which could benefit from national funding.
Lawmakers from the two main opposition parties, the Bulgarian Socialist Party (BSP) and the Movement for Rights and Freedoms (DPS) described the move as "discrimination" against hospitals which have invested in new activities and services.
But Health Minister Petar Moskov warned the new bill would enable "investment in [facilities] that exist."
