The addition of an ambulatory surgical center in Vermont like the one being proposed in Chittenden County is precedent setting.
The three remaining members on the five-seat Green Mountain Care Board say they cannot take action because they have not reached a consensus.
Allowing the Green Mountain Surgical Center to open would let independent doctors penetrate a market that has been exclusively controlled by hospitals.
The Green Mountain Care Board on April 13 will hear from investors seeking to build the center in Colchester. Vermont hospitals have opposed the project for nearly two years.
