A physician freelance medical writer can make very good money. Freelance medical writers who are doctors typically charge by the hour. The hourly rate for physician writers can be $100-$150 or even more. This means that successful freelancers can earn well over $200,000 per year.
If you are a doctor who likes to write, becoming a freelance medical writer might be a great fit for you. The assignments can be diverse, you have many employers not one (which spreads out your risk), and the work can be done remotely from your home. Boards and a license are typically not required, so freelance writing can be a particularly good fit for a physician who has not completed residency.
