Most Common CPT Codes: Know It All

Those seeking a career in medical coding must know about common CPT codes. These codes are extensively used by health practices to identify patient health services in a medical bill. With the help of these codes, insurance payers determine services taken by their clients, so that they can pay for them. This is an important part of revenue generation as it decides whether reimbursement will be made or not.

This dependency on reimbursement payment by the insurance company to the hospital has made it crucial to know commonly used codes. Any mistake in the code may lead to a claim denial, which in return, will damage your career reputation.

To help you excel in your career, we have collected the list of common CPT codes, that you will have to use during medical billing.

A Quick Overview Of CPT Codes

CPT is the acronym of Current Procedural Terminology and the term CPT codes signify code sets that are used by all health practices to report medical, diagnostic, and surgical procedures and services provided by physicians, non-clinical workers, laboratories, and outpatient facilities.  

CPT is under the control of the American Medical Association (AMA), which is also the inventor of these codes. There is a sort of editorial panel working under AMA. They are responsible for managing, revising, upgrading, and deletion of common CPT codes. This panel comprises 21 members, that collectively decide which new code to introduce and which one to delete altogether.

3 Categories Of CPT Codes

All codes are approved by the Food and Drug Administration (FDA) authority, after which it is associated with a certain health service. Common CPT codes are divided into 3 categories:

Category 1: This category contains codes that are used more than any other codes by health practices. This is the broadest group of all

Category 2: This category involves common CPT codes that are supplementary. These codes are used to track health practice performance and are not a must-part of a medical bill. That means a bill may be completed without using codes included in this category.

Category 3: This category includes those common CPT codes that are assigned to new or emerging health services. A code may remain in this category for up to 5 years, after which the pattern is examined by the FDA. If these codes show high application in the health sector, they are approved and sent to category 1. But if these codes show the least or rare usage, they are eliminated or deleted completely.

How CPT Codes Are Used In Medical Bills?

The medical billing process passes a number of procedures, from patient appointment booking to claim submission. But common CPT codes show its application only during bill creation.

The process begins when a patient books an appointment and the information is taken by the hospital staff. When he visits the hospital, personnel collects further personal and insurance details, after which the treatment starts. 

When the patient has taken all of the medical services and is discharged from a hospital, medical coders are required to list each health service taken and equipment used by the patient during the entire treatment, in a medical bill. Here common CPT codes play their part. These codes help identify a medical service, after analyzing which, the insurance payer will make reimbursement.

In a medical bill, 2 other types of codes along with common CPT codes are used, that specify the patient’s medical treatment as a whole:

  • CPT Codes: It defines the medical services a patient received
  • HCPCS Codes: What equipment was used during the treatment?
  • ICD-10-CM: It explains the justification for the use of certain equipment and the reason of given medical services.
