Interpreters are bound by the same regulations.  When hiring an interpreter to provide services as a means for you and your staff to provide medical care, the interpreter becomes a part of the covered entity.  The privacy rule of HIPAA (PL 104-191) permits the disclosure of protected health information to interpreters/interpreting service providers.  Depending on the business relationship with the interpreter/interpreting service provider, you may need to execute a business associate contract.
