According to one legal services firm, frontline NHS services in Lincolnshire will be affected by the proposed change in compensation laws.
According to the National Accident Helpline patients will be deterred from claiming compensation by the legislation to curb the use of "no win, no fee" offers.
As a consequence, the change will result in up to £3 million being spent on compensation, rather than hospital services in the county, according to the organization.
A Freedom of Information (FOI) Act request to the Department of Health by the organization obtained this figure.
It revealed that Lincolnshire NHS trusts claimed the £3 million sum in legal aid in the past financial year.
£1.89 million were claimed by the United Lincolnshire Hospitals NHS Trust (ULHT), with Northern Lincolnshire and Goole NHS Foundation Trust claiming the remainder.
According to the National Accident Helpline, in the next year, anywhere up to this figure could be spent on care for patients, who would have previously had the costs covered by compensation claims.
