NHS South Lincolnshire Clinical Commissioning Group (CCG) has been awarded full responsibility for planning and buying health services.
The groupis responsible for area including Spalding, Bourne, Market Deeping, Holbeach and Long Sutton.
It is one of four emerging NHS organisations in Lincolnshire that was assessed against 119 criteria as part of a rigorous scrutiny exercise known as authorisation.
In April 2013, NHS England was satsfied with 103 criteria and granted NHS South Lincolnshire CCG authorisation with 16 conditions.
But it has now provided evidence it has the ability to succeed and all conditions have been lifted.
Dr Miles Langdon, chairman of the CCG, said: “We are delighted to be recognised by NHS England for our performance and ability to invest in high quality health services for local people.
“Our CCG provided further evidence of strategic planning, arrangements for finance and governance and partnership working to achieve this.
“The 15 GP practices which make up our CCG will continue to work together to help the people of south Lincolnshire to live longer and healthier lives.”
