*Rendering/Servicing-Only Provider is a Type 1 (Individual) NPI who renders services strictly on behalf of an organization, clinic or group practice.

Individual CPDH are not eligible for direct MHCP reimbursement and must enroll with a group affiliation to receive reimbursement at the group level for all dental hygiene services rendered to MHCP enrollees. As part of this process, MHCP requires individual National Provider Identifiers (NPIs) and affiliation with one or more of these enrolled group providers. Additional information is available here.
