Eye (B8) ICD-10-PCS
The B8 body system covers Imaging procedures on eye, with 102 ICD-10-PCS codes across 4 root operations, 94 of them billable in fiscal year 2026. Each root operation defines a distinct procedural objective, and the info icons show the official definition with a preview of the codes inside.

About the B8 Body System
The ICD-10-PCS root operation for the Eye in the Imaging section includes several diagnostic techniques that produce visual representations of ocular structures. These imaging procedures help in detecting, monitoring, and diagnosing eye conditions.
The eye imaging codes cover different modalities such as Plain Radiography (code B80), which uses external ionizing radiation to produce a planar image. More advanced techniques include Computerized Tomography (CT Scan) (code B82), which generates multiplanar images from multiple exposures, and Magnetic Resonance Imaging (MRI) (code B83), which captures radio frequency signals within a magnetic field for detailed cross-sectional views. Additionally, Ultrasonography (code B84) offers real-time visualization by using high-frequency sound waves to image ocular anatomy or blood flow. Together, these procedures represent the range of diagnostic imaging methods coded under root operation B8 for the eye, enabling precise clinical assessment without invasive intervention.
Questions About This Page
How many codes are in the B8 body system?
The B8 body system contains 102 ICD-10-PCS codes in FY 2026, organized into 4 root operations. 94 of them are billable on inpatient claims.
What is a root operation?
The root operation is the third character of every ICD-10-PCS code and names the objective of the procedure. Drainage takes fluid out, Excision cuts out a portion of a body part, and Resection removes all of one. Picking the right root operation is the central skill of PCS coding, so each one above carries its official CMS definition.
