CPT 77011: CT-Guided 3D Localization of Small Internal Targets
CPT code 77011 denotes CT-guided localization using a three-dimensional coordinate system to identify small internal targets. This image-guided procedure supports accurate targeting for diagnostic sampling, marking, or preoperative localization and is commonly performed in hospital outpatient imaging suites and ambulatory radiology centers. Nationally, the code matters because precise localization can reduce operative time, improve diagnostic yield, and influence downstream imaging and procedural care.
Key payers typically involved in coverage and reimbursement for this service include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find benchmarks for utilization and reimbursement patterns, a summary of payer coverage considerations, and clinical context on when three-dimensional CT localization is used. The publication also covers coding nuances, common modifiers, and related procedural codes where available. Practical takeaways include the clinical settings where 77011 is most applicable and the types of services that commonly accompany CT-guided localization.

Billing Code Overview
CPT code 77011 describes a procedure in which the provider uses computed tomography (CT) guidance to localize small targets inside the body using a three–dimensional coordinate system. The procedure is a form of image-guided localization that facilitates precise access to small or hard-to-visualize lesions for diagnostic or interventional purposes.
Service type: Image-guided localization using CT-based three-dimensional coordinate targeting.
Typical site of service: Hospital outpatient imaging suites, ambulatory imaging centers, or radiology departments where CT guidance and interventional localization are performed.
