How To Use CPT Code 70470

CPT 70470 describes the diagnostic radiology procedure of computed tomography (CT) of the head or brain. This article will cover the description, official definition, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, similar codes and billing examples.

1. What is CPT Code 70470?

CPT 70470 is used to report a diagnostic radiology procedure known as computed tomography (CT) of the head or brain. This procedure involves the use of specialized imaging equipment to create detailed cross-sectional images of the head or brain. It is typically performed to diagnose and evaluate various conditions and abnormalities within the head or brain, such as tumors, bleeding, or infections.

2. Official Description

The official description of CPT code 70470 is: ‘Computed tomography, head or brain; without contrast material, followed by contrast material(s) and further sections.’ This code specifically refers to the performance of CT scanning of the head or brain without the use of contrast material, followed by the administration of contrast material and additional imaging sections if necessary.

3. Procedure

1. The provider begins by performing CT scanning of the head or brain without the use of contrast material. This initial scan provides a baseline image of the area of interest.
2. If deemed necessary, the provider then administers contrast material to the patient, either orally or intravenously, to enhance the visibility of certain structures or abnormalities.
3. Following the administration of contrast material, the provider performs additional imaging sections to capture more detailed images of the head or brain.
4. The resulting images are then analyzed and interpreted by the provider to make a diagnosis or evaluate the condition being investigated.

4. Qualifying circumstances

CPT 70470 is typically performed when there is a need to evaluate the head or brain for potential abnormalities or conditions. This may include suspected tumors, bleeding, infections, or other issues affecting the head or brain. The use of contrast material may be necessary to enhance the visibility of certain structures or abnormalities. The procedure is performed by a qualified healthcare professional, such as a radiologist or other trained medical personnel.

5. When to use CPT code 70470

CPT code 70470 should be used when a provider performs CT scanning of the head or brain without the use of contrast material, followed by the administration of contrast material and additional imaging sections if necessary. It is important to note that this code specifically refers to the use of contrast material in the procedure. If CT scanning of the head or brain is performed without contrast material, a different CPT code should be used.

6. Documentation requirements

To support a claim for CPT 70470, the provider must document the following information:

• Reason for the procedure and the specific condition being evaluated
• Details of the CT scanning procedure, including whether contrast material was used and the route of administration
• Any additional imaging sections performed and the reason for their necessity
• Interpretation and analysis of the resulting images
• Signature of the provider performing the procedure

7. Billing guidelines

When billing for CPT 70470, it is important to ensure that the procedure was performed as described in the official definition. The use of contrast material and additional imaging sections should be documented and supported by medical necessity. It is also important to follow any specific billing guidelines provided by payers or insurance companies. Providers may need to separately report the contrast material using a supply code or a HCPCS Level II code, depending on payer guidelines.

8. Historical information

CPT 70470 was added to the Current Procedural Terminology system on January 1, 1990. Since then, there have been some historical changes to the code, including a code change on January 1, 2003, which updated the description of the procedure.

9. Examples

1. A patient undergoes CT scanning of the head to evaluate a suspected brain tumor. The procedure is performed without contrast material initially, followed by the administration of contrast material and additional imaging sections to further assess the tumor.
2. A trauma patient receives CT scanning of the head to assess for any intracranial bleeding. The procedure is performed without contrast material, followed by the administration of contrast material and additional imaging sections to evaluate the extent of the bleeding.
3. A patient with suspected sinusitis undergoes CT scanning of the head to assess the sinuses. The procedure is performed without contrast material initially, followed by the administration of contrast material and additional imaging sections to evaluate the presence of infection or other abnormalities.
4. A patient with chronic headaches undergoes CT scanning of the head to investigate potential causes. The procedure is performed without contrast material, followed by the administration of contrast material and additional imaging sections to evaluate for any structural abnormalities or other underlying conditions.
5. A patient with a history of head trauma undergoes CT scanning of the head to assess for any skull fractures or intracranial injuries. The procedure is performed without contrast material initially, followed by the administration of contrast material and additional imaging sections to evaluate the extent of the injuries.
