Medical Billing and Coding Course

A typical day for a Medical Biller and Coder begins with logging into the healthcare facility’s electronic health record (EHR) system. The day’s workload often includes reviewing dozens of patient charts from recent appointments or procedures. Each chart must be examined carefully to assign the correct ICD-10-CM diagnosis codes, CPT® procedure codes, and, if applicable, HCPCS Level II codes for supplies or medications. Accuracy is critical — one wrong code could result in a denied claim or a delay in payment.

Once coding is completed, the next phase involves claim submission. This means sending coded patient information to insurance companies through electronic clearinghouses. Billers must ensure that all required information is attached to each claim — from insurance details and provider credentials to authorizations and modifiers. If anything is missing or incorrect, the claim will likely be rejected or denied, resulting in lost revenue for the healthcare provider and more work for the billing team.

Throughout the day, medical billers and coders also spend time handling denials and resubmissions. When a claim is denied — whether for incorrect coding, missing information, or issues with insurance eligibility — it’s the biller’s job to investigate, correct the errors, and resubmit it promptly. This part of the job requires strong problem-solving skills, patience, and excellent attention to detail. Many billers communicate directly with insurance companies to clarify claim requirements or appeal rejected charges.

Collaboration is also a major part of the day. Billers and coders often work closely with physicians, nurses, and office managers to clarify documentation and verify that records meet payer requirements. They may have to ask providers for more details on a procedure or confirm that certain diagnoses were included. In larger settings, the billing team may also meet with compliance officers to review updates to coding guidelines or ensure the organization remains HIPAA-compliant. 

By the end of the day, a medical biller and coder will have helped ensure that their healthcare organization is reimbursed properly and efficiently. But beyond the numbers and codes, they are essential players in the financial stability of the practice and the overall quality of care. Without accurate billing and coding, providers can’t be paid, and patients may face unexpected issues with their insurance. It’s a role that combines technical skill, healthcare knowledge, and real-world impact and you can do it!
