As a registered health information technicians (RHIT), you verify the accuracy of electronic medical records. Your duties include data entry, research, and verification of information. When you find a medical record that is not accurate or is incomplete, you contact health care providers or doctors to obtain the correct information and then update the patient record accordingly. Some RHITs use software to analyze patient records to find ways to cut costs and develop more efficient service provision. RHITs work in hospitals and other healthcare facilities and public agencies.
