How Used CPT Codes?

Current Procedural Terminology (CPT) codes help healthcare providers track and report medical services and procedures. The specific CPT codes attached to each service or procedure help maintain accuracy and efficiency in medical billing and reporting.
Insurers use CPT codes to determine how much money to pay providers. The same CPT codes are used by all providers and payers to make the billing process consistent and to help reduce errors.

What Are CPT Codes?
A CPT code is a number used to identify a medical service or procedure. CPT codes are used by healthcare providers for reporting, billing, and administration purposes.
Some CPT codes are only used occasionally, and some are not really used at all. Other CPT codes are used frequently. For example, 99213 and 99214 are codes for general office visits, usually to address one or more new concerns or complaints, or to follow up on one or more problems from a previous visit.
The American Medical Association (AMA) develops, maintains, and has copyrighted the CPT codes that are currently used in over 60 countries. These codes can change as healthcare changes, and new codes can be made and assigned to new services.
Current CPT codes can also be revised and unused codes thrown out. Thousands of CPT codes are used and updated every year.

Types of CPT Codes
CPT codes are five digits. Most consist of only numbers but some have numbers and letters. There are several categories of CPT codes:
Category I: Procedures, services, devices, and drugs (including vaccines)
Category II: Performance measures and quality of care (for example, patient follow-up)
Category III: Services and procedures using emerging technology (these codes are usually temporary while the service or procedure is still fairly new)
PLA codes: Used for lab testing
List of CPT codes
Here are some examples of CPT codes:
99397 can be used for a preventive exam if you are over age 65.
90658 can be used for the administration of a flu shot.
90716 can be used for the administration of the chickenpox vaccine (varicella).
12002 can be used when a healthcare provider stitches up a 1-inch cut on your arm.
87635 can be used when you're given a COVID-19 Tes T

How CPT Codes Are Used
CPT codes directly affect how much a patient will pay for the medical care they receive.
Provider offices, hospitals, and other medical facilities are strict about how CPT coding is done. They hire professional medical coders or coding services to make sure that services are coded correctly.
Initial coding: Your healthcare provider or their office staff will list which CPT codes apply to your visit. If they use an electronic health record (EHR) during your visit, it will be noted in that system. These systems usually let staff call up codes based on the service name.
Verification and submission: Medical coders and billers examine your records to make sure the correct CPT codes are assigned. Then, the billing department submits a list of your services to your insurer or payer. Most healthcare providers store and transfer this information digitally, but some are still done by mail or fax.
Claims processing: Your health plan or payer uses CPT codes to process the claim. They will decide how much to pay your provider and how much you will owe for the services that you receive.
Research: Health insurance companies and government officials use coding data to predict future healthcare costs for the patients in their systems. State and federal government analysts use coding data to track trends in medical care. This information helps to plan and budget for Medicare and Medicaid.

What’s the Difference Between a CPT Code and a ICD Code?
CPT codes have different uses than ICD codes. CPT codes identify the services provided to a patient, and ICD codes identify diagnoses. The CPT code system is managed by the American Medical Association, while the ICD code system is managed by the World Health Organization. 

Where You Will See CPT Codes
You'll see CPT codes in many different documents that you'll get as you move through the healthcare system.
Discharge paperwork: When you are done with an appointment or are discharged from a healthcare facility, you will get some paperwork that includes a summary of the services you had, and the codes for those services. The five-character codes that appear on discharge paperwork are usually CPT codes. There may also be other codes on that paperwork, like ICD codes that indicate a diagnosis (which may have numbers or letters, and usually decimal points).
Bills: When you get a medical bill, it will have a list of the services you received. Next to each service will be a five-digit code—usually, it's the CPT code.​
Explanation of benefits: When you receive an explanation of benefits (EOB) from your payer, it will show how much of the cost of each service was paid on your behalf. Each service will be matched with a CPT code.

What are the six sections of CPT codes?
The six sections of CPT codes are Evaluation and Management, Anesthesia, Surgery, Radiology, Pathology and Laboratory, and Medicine. Each of the six sections also has sections within it that offer more detail about services.

Matching CPT Codes to Services
If you're looking at your healthcare providers' and insurance billing process, you might want to know what all the codes mean.
However, CPT codes are copyrighted by the AMA and they charge a fee to use them.1 That means that you will not find a full list of CPT codes with explanations online for free.
That said, the AMA does provide consumers with a way to look up the CPT codes. Here's how to find out what a CPT code means:
Do a CPT code search on the AMA website. You will first have to register (for free) and are limited to five searches per day. You can search by a CPT code or use a keyword to see what the code for a service might be.
Contact your healthcare provider's office and ask them to help you match the CPT codes and services.
Contact your payer's billing department and ask them to help you with the CPT codes.
You can use the same steps to look up bundled codes.

Preventing Incorrect Coding
Understanding CPT codes can help you make sure that your hospital bill is correct and catch any insurance billing errors—which do happen often. Some patient advocacy groups say that nearly 80% of bills for medical care contain minor errors.8
These simple mistakes can have a big impact on your wallet. In fact, the wrong CPT code can mean that your insurance will not cover any of the costs.
Always review your bill carefully and compare it with your EOB to check for mistakes. It's not uncommon for healthcare providers or facilities to code for the wrong type of visit or service (typographical errors).
There are also fraudulent practices like "upcoding," which is when you are charged for a more expensive service than the one you got. On the other hand, "unbundling" is when bundled services or procedures are billed as separate charges.
If you come across something in your medical bill that doesn't add up, call your provider's office. It could be a simple mistake that the billing department can fix.

Limitations of CPT Codes
While they are meant to help make the billing process in healthcare more uniform, the existence of CPT codes does not mean that everyone defines a healthcare service the same way.
CPT codes also do not ensure that different healthcare providers will get paid the same amount for the same service because payment is outlined in the contracts between providers and insurers.
For example, Healthcare Provider A may perform a physical check-up (99396) and be paid $100 by your insurance company. However, if you went to Healthcare Provider B, the payment for that same CPT code might only be $90.

HCPCS Codes
CPT are not the same as the Healthcare Common Procedure Coding System (HCPCS), but they are similar. If you use Medicare, you'll see HCPCS codes in your paperwork instead of CPT codes.
HCPCS codes are used and maintained by the Centers for Medicare & Medicaid Services (CMS). They are used to bill Medicare, Medicaid, and many other third-party payers.

HCPCS Code Levels
Level I codes are based on CPT codes and are used for services and procedures that are offered by healthcare providers.
Level II codes cover healthcare services and procedures that are not performed by healthcare providers.
HCPCS level II codes start with a letter and have four numbers. They may also have extra modifiers—either two letters or a letter and a number. Examples of items billed with level II codes are medical equipment, supplies, and ambulance services.
HCPCS level II code lists can be found on the CMS website. Level I codes, however, are copyrighted by the AMA just like CPT codes
