CPT Code 74176: Description & Reimbursement Guidelines

Radiology services are required in almost all medical specialties. They are always in demand. However, what you might not know is that radiology also has the third-highest denial rate (20%) out of all specialties. Many of these denials come from computed tomography (CT) scans. 

CPT code 74176 is a frequently used code to represent CT scanning. We have created this guide to explain to you everything you need to know about 74176. We will discuss when to use it, which modifiers apply, and how to secure proper reimbursement. So, let’s start.

CPT Code 74176 – Description

CPT code 74176 is defined as:

“Computed tomography, abdomen and pelvis; without contrast material.”

As evident from the definition, 74176 is a radiology billing code. It is used for a CT scan that covers both the abdominal and pelvic regions in a single session. What’s important to note here is that no intravenous contrast is used during the study. However, what many billers miss is that if the contrast material is given orally or via rectum, it still counts as a “non-contrast” study. So, oral or rectal contrast is allowed. 

Because this is a combined code, both regions must be imaged. If only the abdomen or only the pelvis is scanned, separate codes apply. Also, in most cases, only one combined CT scan is allowed on a single claim. But it is not a fixed rule, and sometimes more than one combined study might be required. In this type of situation, you must append modifier 59 or XE to the second CT scan. 

CPT code 74176 is closely related to two more codes. Here’s how they are different:

• CPT 74177: Computed tomography, abdomen and pelvis, with contrast material.
• CPT 74178: Computed tomography, abdomen and pelvis, with and without contrast material in one or both body regions.

Appropriate Use Cases for CPT Code 74176

To make things clear, let’s look at a couple of real-world scenarios in which CPT code 74176 can be used.

Suspected Perforation   

For our first scenario, suppose that a 52-year-old man presents to the physician’s office complaining of sharp and sudden abdominal pain. He also feels nauseous and feverish. The physician gently presses on the patient’s stomach, upon which the patient winces in pain. 

Since the patient has a history of nonsteroidal anti-inflammatory drugs (NSAIDs) overuse, the physician suspects bowel perforation in the intestinal lining. The patient also tells the physician that he is allergic to contrast material. Hence, a CT scan of the abdomen and pelvis is ordered without intravenous contrast to check for bowel perforation, which can be a life-threatening condition.  

In this case, the radiology billing department can use CPT code 74176 to bill the CT scan. 

Kidney Stones

Let’s look at another scenario. Suppose a 28-year-old man visits the hospital with severe flank and lower abdomen pain. He also mentions feeling a burning sensation while urinating. The physician checks his vitals and notices that the patient has a fever. These symptoms prompt the physician to suspect kidney stones. Hence, a CT scan of the abdomen and pelvis is ordered without intravenous contrast. 

The imaging reveals the presence of kidney stones in the bladder, as bright white, high-density solid spots are seen in the organ. 

In this scenario, CPT code 74176 can be used to bill the CT scan. 

Modifiers to Append with CPT Code 74176

Here are some modifiers that are commonly used with CPT code 74176:

Modifier	Description	Usage
26	Professional Component	Used to bill the physician’s interpretation and report.
59	Distinct Procedural Service	Indicates that the procedure is distinct and separate from other services performed on the same day.
CT	Equipment Non-compliance	15% payment reduction. Used when equipment used to furnish certain services does not meet attributes of the National Electrical Manufacturers Association (NEMA) Standard XR-29-2013.
TC	Technical Component	It is used when billing only for the technical aspects, including equipment, supplies, and the technician’s services.
XE	Separate Encounter	Indicates that the service is distinct and separately reimbursable because it was performed during a separate encounter on the same service date.

Reimbursement Guidelines for CPT Code 74176

Here are some important guidelines about CPT code 74176 that you must follow to reduce your chance of claim denials:

Establish Medical Necessity with ICD-10 Codes

Like all CPT codes, you must provide detailed documentation and a valid ICD-10 diagnosis code in your claim that justifies the CT scan. Here are some commonly used ICD-10 codes with 74176:

• K35.80: Unspecified acute appendicitis 
• K63.1: Perforation of intestine (nontraumatic) 
• K66.1: Hemoperitoneum 
• N18.4: Chronic kidney disease, stage 4 (severe) 
• N20.0: Calculus of kidney
• N20.1: Calculus of ureter 

Mention Timing for Multiple Scans

If multiple CT scans are performed on the same date during a single encounter, you must specify the exact time each scan was conducted. 

Additionally, include a note indicating that the scans were performed during the “same session.” For example: 9:00 AM – CPT code 74176; 9:30 AM – CPT code 74177 (same session).

Equipment Requirements

Apart from the medical guidelines, there are some requirements for the CT equipment as well:

• The equipment model must be FDA-approved.
• The model should be in its full market release phase.

Final Thoughts on CPT Code 74176

In this blog, we tried our best to simplify CPT code 74176 for you. Here is a quick recap. 

• 74176 is used to bill a combined CT scan of the abdomen and pelvis.
• No contrast is used in the scan.
• Always use the correct modifiers and provide a valid ICD-10 diagnosis code.
• Make sure the equipment meets the guidelines.

However, if you experience frequent denials, you can always seek help from professional billing companies. Many reputable companies like NeuraBill offer expert radiology billing services at competitive rates.
