Medical data entry jobs focus on creating medical records based on specimen or patient data. As part of this job, you may use medical coding to describe patients and their situation, submit billing requests to insurance companies, update digital systems with records of treatment success rates, or perform other clerical tasks. You may also be required to identify problems with missing information, decipher handwriting from both doctors and patients, and interpret test results. Medical data entry jobs are most common in healthcare facilities like hospitals, but a smaller number of positions exist at universities and other research institutions.
