I have worked as a Medical Reviewer for doctors in the US under California Workers Compensation. I review medical records of claimants and interprets and write medical reports for the doctors to review. As a Medical Transcriptionist I typically do the following: Listen to the recorded dictation of a doctor or other healthcare professional Transcribe and interpret the dictation into diagnostic test results, operative reports, referral letters, and other documents Review and edit drafts prepared by speech recognition software, making sure that the transcription is correct, complete, and has a consistent style Translate medical abbreviations and jargon into the appropriate long form
