The Certificate of Need (CN) program is a regulatory process that requires certain healthcare providers to obtain state approval before building certain types of facilities or offering new or expanded services. Program staff members are available to provide technical assistance to you before submitting your application. Staff members are also available to help you determine if a Certificate of Need is necessary.
Certificate of Need determines need according to factors that are variable in relation to the proposed services.
