Did you know that poor billing practices cause American doctors to lose around $125 billion each year? Medical billing and coding has many challenges.
If you keep up with our blogs or work in the industry, you know exactly what I’m talking about. Even if you’re new here, or just getting started in your career, the American healthcare system should speak for itself - nothing about it is straightforward.
So why would it be any easier on the backend?
Don’t panic! We are here to help you avoid unnecessary billing and coding mistakes so you can collect your revenue promptly. Avoid putting stress on your billing team by preparing for the more common mistakes. Preventing denial codes is essential if you want to keep a steady revenue flow.
For example, two terms are commonly misunderstood by billing professionals. By misunderstood, I mean people usually confuse them with one another. This is an easily preventable billing error, which we are going to go over in this blog. HCPCS (Healthcare Common Procedure Coding System) and CPT (Current Procedural Terminology) codes are similar in function, but with important differences which dictate their usage.
These two coding systems both handle medical procedures and services. However, HCPCS classifies those procedures and services, while CPT codes describe them. Let’s look at the differences between both codes, why they are important, and why you should know the difference.

The Difference Between HCPCS & CPT Codes
HCPCS and CPT codes are both coding systems that report medical procedures and services. Used frequently in the medical and billing industry, it is important to fully understand the differences between the two. This is especially true when considering revenue cycle management and claim denial percentages. The main difference between these codes lies in their:
Purpose.
Structure.
Usage.
Developed and maintained by the American Medical Association (AMA), CPT codes describe and report medical, surgical, and diagnostic procedures/services for billing purposes. However, Medicare and other insurance cover a variety of different services and supplies, some of which aren’t identified by CPT codes.
This is why we have HCPCS codes. This is the other main set of procedure codes that classify medical services. Note that HCPCS draws from the AMA’s Current Procedural Terminology (CPT). These codes assist healthcare workers in reporting different medical procedures and services to health insurance programs, such as Medicare and Medicaid.
However, there are different levels to the HCPCS, which offer various degrees of coverage that CPT-4 (Edition 4) does not. For a better grasp of things, let’s go over the structures for each code.
HCPCS Code Structure
The HCPCS exists in the public domain created by the Centers for Medicare and Medicaid Services. These codes are alphanumeric and fall into two principal subsystems: Level I and Level II. Level I consists of Current Procedural Terminology (CPT-4), while Level II identifies products, supplies, and services not covered by CPT-4 codes.
Level I focuses on codes that report services and procedures performed to payers by physicians, non-physician practitioners, hospitals, laboratories, and outpatient facilities. Level II is the national procedure code set for healthcare practitioners, providers, and medical equipment suppliers which identifies products, supplies, and other services not covered by CPT-4 codes.
These include:
Ambulatory services.
Durable medical equipment.
Prosthetics.
Orthotics.
Supplies (DMEPOS) when used outside of a physician’s office.
Level II codes consist of one alphabetical letter followed by four numbers. Check out our list of the different meanings for the following alphabetical letters you can find in a level II HCPCS code:
A Codes - Transportation, medical supplies, surgical supplies, misc and experimental.
B Codes - Enteral and parenteral therapy.
C Codes - Temporary outpatient hospital prospective payment system.
D Codes - Dental procedures.
E Codes - Durable medical equipment.
G Codes - Professional services and temporary procedures.
H Codes - Rehabilitative services.
J Codes - Drugs administered (other than oral methods and chemotherapy drugs).
K Codes - Temporary codes for durable medical equipment regional carriers.
L Codes - Prosthetic or orthotic procedures.
M Codes - Medical services.
P Codes - Pathology and laboratory.
Q Codes - Temporary codes.
R Codes - Diagnostic radiology.
S Codes - Private payer codes.
T Codes - State Medical agency codes.
V Codes - Vision and hearing.
There was a Level III, although this was discontinued in 2003 and is no longer accepted.
HCPCS Examples
Here are a few examples of some popular HCPCS codes and their meanings:
E0260 - Use of a semi-electric hospital bed as part of treatment.
A9270 - Use if a service is not covered by Medicare or Medicaid. There is no equivalent CPT code as CPT does not include provisions for non-covered service.
A0425 - Ambulance transportation (ground mileage).
G9631 - Ureter injury during time of surgery or discovered up to 30 days post-surgery.
V2599 - Contact lens, other type.
R0070 - The transportation of personnel and portable X-ray equipment to nursing homes or other residency. For multiple patients, use code R0075.
CPT Code Structure
We already went into what CPT stands for and why we need this medical code set, but I’ll go over it again just for a quick review.
Current Procedural Terminology (CPT) is a medical coding system that healthcare professionals use to report the following procedures and services:
Medical.
Surgical.
Diagnostic.
The system is an essential tool in any medical biller’s toolbelt, as it serves as a uniform language for communicating information about these procedures and services in a healthcare setting. CPT codes are a five-digit numeric code which falls under one of three categories. The categories are as follows:
Category 1: The most commonly used CPT codes. These codes describe most basic healthcare services and procedures. There are six subcategories of this category, which are:
Evaluation and Management.
Anesthesia.
Surgery.
Radiology.
Pathology.
Laboratory.
Medicine.
Category 2: This category contains optional performance measurement codes. These codes provide data about the quality of care given. This category is helpful for data collection, measurement, and analysis.
Category 3: These are temporary codes. They are for emerging and experimental practices. These codes allow for data collection on new services, procedures, and technologies to substantiate widespread usage.
CPT Examples
Here are a few examples of some popular CPT codes and their meanings:
99214 - Office visit.
99397 - Preventive exam (over the age 65).
90658 - Administration of a flu shot.
99213 - Office or other outpatient visit to evaluate and manage an established patient.
20610 - Aspiration and/or injection of a large joint or joint capsule.
71020 - Chest X-ray.
Why You Should Know the Difference Between HCPCS & CPT
Understanding the difference between HCPCS and CPT codes is essential in more ways than one. This is true, especially in the world of medical billing. The financial health of your healthcare organization falls in the hands of those who work with your patient invoices. With accuracy, comes a faster turnaround and a lower percentage of claim denials. Here are some other ways having your team familiar with these codes can help your practice.
Accurate Billing and Reimbursement
I mentioned financial wellness already, but I would bet that is every business’s number one priority, so let’s dive deeper into the subject. Being able to accurately and confidently code for a wide range of services means your billing team is less likely to have issues with underpayment or overpayment of invoices. From medical procedures to equipment, each corresponding code ensures that healthcare providers are accurately reimbursed for their services.
Efficient Communication
Utilizing these codes properly strengthens the standardized language for documenting and communicating medical services. Understanding the differences between HCPCS and CPT codes facilitates this communication between healthcare providers, insurance companies, and patients. With better communication practices come lower chances of denied or delayed claim submissions. Therefore, faster reimbursement!
Data Analysis and Research
Using HCPCS and CPT codes correctly also helps medical researchers collect public health data. These codes function as essential tools which help to identify trends in healthcare services. They also assist in tracking the prevalence of specific procedures as well as studying the cost of healthcare across the country. Data gathered from this can help inform policy decisions as well as contribute to the bettering of the healthcare industry.
Regulatory Compliance
All organizations that work with protected health information (PHI) must comply with the Health Insurance Portability and Accountability Act (HIPAA). Using HCPCS and CPT codes enables organizations to safely communicate this PHI within the company and to other covered entities.
HIPAA’s billing and coding standards require the use of both sets of codes for all electronic healthcare transactions. Non-compliance can lead to issues with collecting your revenue and even worse potential legal consequences.
Conclusion
Knowing the difference between HCPCS and CPT codes is essential if you work in the healthcare industry. Coders and billing staff can use this knowledge to ensure the most accurate of billing practices. With an accurate billowing practice, you can expect to see better communication within your organization, more timely reimbursement, and compliance with regulations.
Remember, CPT codes cover most medical procedures and services covered by insurance. HCPCS codes report medical supplies, equipment, and services that aren’t included in CPT codes. Understanding how each code works with the other will help you continue to collect your claims and keep your revenue cycle healthy.
