Understanding 99204 RVU


The Relative Value Unit (RVU) is a critical component in the medical billing and coding industry, and understanding it is essential for healthcare providers. One of the most commonly used codes is the 99204 RVU. This article provides an in-depth look at the 99204 RVU, its components, and its role in medical billing. 

What is 99204 RVU? 

The 99204 RVU is a specific code used in the healthcare industry to denote a particular type of patient evaluation and management service. This code is used for new patient office or other outpatient visits that typically require 45 minutes of face-to-face time with the patient. 

RVUs are used to determine the amount of reimbursement a healthcare provider will receive for a particular service. They take into account the time, skill, and resources needed to provide a service, making them a crucial part of the healthcare reimbursement process. 

Components of 99204 RVU 

Work RVU 

The Work RVU (wRVU) is a measure of the physician's time and intensity required to provide a service. For the 99204 code, the wRVU is relatively high, reflecting the complexity and time involved in a new patient visit. 

Work RVUs are determined by a variety of factors, including the time it takes to perform the service, the technical skill and physical effort, the mental effort and judgment required, and the stress due to the potential risk to the patient. 

Practice Expense RVU 

The Practice Expense RVU (peRVU) covers the costs of maintaining a practice, such as rent, equipment, supplies, and non-physician staff costs. For the 99204 code, the peRVU is also taken into account, as these visits often involve the use of medical equipment and supplies. 

Practice Expense RVUs vary by specialty and by the type of service provided. They are determined based on surveys of physician practices and are updated periodically to reflect changes in practice costs. 

Malpractice RVU 

The Malpractice RVU (mRVU) accounts for the cost of professional liability insurance. The mRVU for the 99204 code is relatively low, reflecting the lower risk associated with an office visit compared to more invasive procedures. 

Malpractice RVUs are determined based on the average malpractice insurance premium cost for each specialty. They are updated periodically to reflect changes in malpractice insurance costs. 

How 99204 RVU Impacts Medical Billing 

The 99204 RVU plays a significant role in medical billing. The total RVU for a service is calculated by adding the work RVU, the practice expense RVU, and the malpractice RVU. This total RVU is then multiplied by a conversion factor to determine the reimbursement amount. 

Understanding the 99204 RVU and how it is calculated can help healthcare providers ensure they are being reimbursed appropriately for their services. It can also help them identify areas where they may be able to improve efficiency or reduce costs. 


The 99204 RVU is a crucial part of the healthcare reimbursement process. By understanding its components and how it impacts medical billing, healthcare providers can better navigate the complex world of medical coding and billing. 

While the 99204 RVU is just one of many codes used in the healthcare industry, it serves as a useful example of how RVUs work and why they are so important. Whether you are a healthcare provider, a medical coder, or just interested in the healthcare industry, understanding RVUs is essential.
