Health care professionals practicing under a group or facility are called servicing providers. To find out if you are eligible to be a servicing provider, please refer to the listing of eligible provider types for Washington.
Important! The group or facility under which you practice must be enrolled with HCA as a billing provider and have a Core Provider Agreement with the agency. Servicing provider applications submitted without a billing provider will be denied.
