Frequently asked questions about Medical Coders


What is the difference between a Medical Coder and a Medical Biller?

Medical Coders and Medical Billers work together to make sure that healthcare providers receive payment for their claims. Medical Coders work behind the scenes to translate medical records into a series of codes, making it easy for insurers to quickly confirm or deny a claim. After completing a patient’s file, Medical Coders pass the information to Medical Billers, who communicate with patients and insurance representatives about the outstanding balance associated with an account. If an insurance provider denies a claim, Medical Billers prepare invoices for patients to pay out -of-pocket and arrange payment plans when necessary.


What are the daily duties of a Medical Coder?

Medical Coders usually work standard office hours alongside other medical office staff. After a patient completes their visit, the Medical Coder reads their chart or file and classifies the information from their appointment into different categories. If they are unsure about the type of code for a certain treatment, the Medical Coder references medical coding guidelines and researches the correct code. They carefully put the codes in sequence and submit them to the patient’s insurance provider or to the Medical Biller on their staff. If there is an issue with a submission, they review existing codes and document any corrections.


Do Medical Coders have different responsibilities in different industries?

Medical Coders have the same basic role regardless of what kind of medical office they work in, but they can use different types of coding systems for various specialties. Most standard Medical Coders use three main codes: International Classification of Diseases (ICD), Current Procedural Technology (CPT) and Healthcare Common Procedure Coding System (HCPS). Many types of specialized medical offices use their own coding systems, including emergency departments, chiropractic offices, dermatology practices, pain management centers and plastic surgery centers. Medical Coders need to learn the details of each specialty to appropriately process each type of treatment.


What are the characteristics of a good Medical Coder?

The most important characteristic of a good Medical Coder is the ability to pay attention to small details. Many medical codes have a single letter or number that differentiates a treatment from a completely different procedure, and coding mistakes could lead to a claim being denied or a significant delay in receiving payment. Good Medical Coders diligently check their work after translating a file into medical codes, checking that each entry is accurate. They are good at troubleshooting problems with a patient’s file and determining the cause of any discrepancies in someone’s medical history and insurance claim.
