Translators are paid by the hospital/facility/office for their services, usually as a salary as opposed to per hour. Because their services are reimbursed via the facility's payroll, they can't also be reimbursed by a payer. RVUs are not a component of their salary.
Although providers are also on salary and charges can be billed for their services, the reimbursement doesn't go directly to the provider; it goes to the facility. Their salary remains the same, regardless of how many patients they see. That's why (most) facilities have policies on the minimum number of RVUs a provider should be meeting per month (usually). If a provider got paid directly from every claim going out, then there'd be way more incentive to see as many patients as possible, thus lowering patient quality of care.
