Newman's Billing and Coding Professional Research Study Guide, Breaking the Code

Medical coding experts offer an essential action in the medical billing process. While the medical coder and medical biller may be the exact same person or may work closely together to make sure all billings are paid properly, the medical coder is primarily accountable for abstracting and assigning the appropriate coding on the claims. The coder must assign CPT codes, ICD-9 codes and HCPCS codes to both report the treatments that were carried out and to offer the medical biller with the information required to process a claim for repayment by the suitable insurance agency.
