A remote RN coder works with medical codes that healthcare providers use for patient records, billing, insurance, and quality assurance. In this career, your duties include using the internet to access patient records and reports. You then assign codes for each diagnosis and procedure that the patient receives in the medical facility’s database. You work with clinical coding systems like the International Classification of Diseases (ICD) and Current Procedural Terminology (CPT) codes. In addition to applying codes, your responsibilities as an RN coder sometimes include auditing the work of other coders to ensure accuracy.
