BQ2 Computerized Tomography (CT Scan) - Non-Axial Lower Bones ICD-10-PCS

About the BQ2 Code Range

The Computerized Tomography (CT Scan) operation in the ICD-10-PCS system, coded as BQ2 under the Imaging classification, refers to a diagnostic procedure using CT technology to create detailed cross-sectional images of specific body parts, particularly targeting non-axial lower bones.

This operation captures high-resolution images of various lower limb structures such as the Hip, Femur, Knee, Tibia/Fibula, Ankle, and other foot and toe components. ICD-10-PCS codes specify laterality (right or left) and whether contrast media of different osmolarity levels—High Osmolar, Low Osmolar, or Other Contrast—is used, or if no contrast is applied. For example, code BQ200ZZ represents a CT scan of the Right Hip using High Osmolar Contrast, while BQ2FZZZ denotes a scan of the Left Lower Leg without contrast. These detailed CT scan codes enable precise documentation of imaging studies crucial for diagnosis, treatment planning, and clinical management of lower extremity bone conditions.
