The two terms “Medical billing” and “Medical coding” are often used interchangeably. These two terms are actually different, yet interconnected, cogs in the healthcare machine. A medical coder takes the complete notes from a patient’s visit and translates them into a universal language of alphanumeric codes. They are the first runner who passes the baton to the medical biller, who then uses those codes to create and submit claims, ensuring the healthcare provider gets paid. Without medical billing and coding, the entire financial process would get stuck.

If you are an independent provider, office manager, or running a private practice, it is important to understand the difference between medical billing vs coding. Here, you will get to know the key differences between medical billing and coding and understand why roles of these both terms are so important.

Medical Billing vs Coding: Differences You Should Know

 

First Step in Healthcare Reimbursement Process: Medical Coding

Medical coding is the primary step in the healthcare compensation process. Medical coding services involves translating healthcare services, procedures, and equipment into standardized alphanumeric codes. These alphanumeric codes are important for insurance claims and for documenting patient records.

The common types of medical codes are ICD-10, CPT, and HCPCS.

Let’s understand the type of medical codes with an example. Let’s say a patient visits a clinic for a routine physical. The coders will convert the doctor’s notes into:

  • ICD-10 Code: Z00.00 (general adult medical exam)
  • CPT Code: 99385 (initial preventive exam)
  • If the coding is not accurate, the billing department won’t know what to charge, and the insurance companies won’t know what to pay.

Medical Billing: Next Step After Medical Coding

Medical billing is the process by which claims to the insurance companies are submitted to receive payment for the services rendered by the healthcare provider. What are the key responsibilities of medical billing? Here is the answer to this question. Some key responsibilities of medical billing may include:

  • Reviewing coded information
  • Preparing and submitting insurance claims
  • Communicating with payers to resolve claim issues
  • Sending statements to patients
  • Tracking payments and handling denials or rejections
  • Coders aim on the clinical side, whereas billers focus on the financial side of healthcare.

How Medical Billing and Coding Work Together

While medical billing and coding are different processes, but are still inseparable when it comes to revenue cycle management. These processes together can help significantly for RCM, and the simplified workflow of medical billing and coding is given below:

  • Patient Visit → Provider documents services
  • The Medical Coder assigns correct codes
  • A Medical Biller uses those codes to generate claims
  • The claim is submitted to the insurance
  • Insurance reviews → Approves, denies, or requests more info
  • Payment is posted or reworked if denied
  • Patient is billed (if applicable)

If there is any breakdown at any point, the payment can be delayed or, in some cases, denied. So, the practices are increasingly dependent on the expert third-party solutions like TueCa RCM™, LLC, to streamline this process.
