Who is a Medical Coder?
After a medical provider conducts a health assessment or treatment of a patient, the government provider or insurance company needs to understand what was done for processing the bill. It’s the role of the medical coder to pass along this information in a way that is useful and efficient. A medical coder is an individual who translates details and information from a patient’s medical documents, such as physician's notes, lab reports, diagnoses and procedures into useful uniform medical codes which are in accordance with the industry-standards. 
In India the demand for medical coders and medical coding courses is rising exponentially as the global healthcare sector also experiences tremendous growth.
Types of Codes used by a Medical Coder
Medical coding includes a number of code sets, each having a different purpose and understanding them is essential for medical coders. There are three types of universally known medical alphanumeric codes primarily used in healthcare settings by the medical coders:
- International Classification of Diseases (ICD): WHO or the World Health Organization created this code which is internationally used by the medical coders for medical coding. ICD is largely used for the purpose of data collection and health recording for diagnosing conditions and diseases. These codes are of great significance to medical coders as these can classify symptoms, illnesses, diseases and causes of death.
- Current Procedural Terminology (CPT): CPT codes in medical coding identify surgical, diagnostic and medical procedures and services. This system was developed for medical coders by the American Medical Association (AMA).
- Healthcare Common Procedure Coding (HCPCS): The CMS or Centers for Medicare and Medicaid Services developed this medical coding system to help with processing insurance claims for various providers such as Medicare. Medical coders use them to note medical equipment, supplies, products, and services.
