Explanation:

Identify the procedure and key terms

Using the CPT Coding and Radiology Coding knowledge points

• Procedure: Diagnostic CT colonography (virtual colonoscopy).
• Key components: Includes image postprocessing.
• Intent: Diagnostic (not screening).

Locate the correct CPT code range

Using the Radiology Coding knowledge point

• Navigate to the Diagnostic Radiology (Diagnostic Imaging) subsection of the Radiology chapter in the CPT manual.
• Look up the index under "Colonography" or "CT Scan, Colon".
• Identify the codes for Computed Tomographic (CT) Colonography:
• 74261: Computed tomographic (CT) colonography, diagnostic, including image postprocessing; without contrast material.
• 74262: Computed tomographic (CT) colonography, diagnostic, including image postprocessing; with contrast material(s) including non-contrast images, if performed.
• 74263: Computed tomographic (CT) colonography, screening, including image postprocessing.

Select the specific diagnostic code

Using the CPT Coding knowledge point

• The prompt specifies "Diagnostic CT colonography including image postprocessing" without mentioning contrast administration.
• In CPT coding, when contrast is not specified, the default diagnostic code for CT colonography is 74261 (without contrast material).
