Eye (B8) ICD-10-PCS
The B8 body system covers Imaging procedures on eye, with 56 ICD-10-PCS codes across 5 root operations, 51 of them billable in fiscal year 2027. 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
These codes describe imaging of the eyes and related sites, including tear ducts, optic foramina, the choroid and retinal blood vessels. The body-part character distinguishes right from left; it also has choices for both eyes and both tear ducts.
The tables separate plain radiography and CT, which use external radiation, from MRI, which uses magnetic fields and radio signals, and ultrasonography, which uses sound waves. CT imaging includes procedures with and without contrast. Other Imaging covers another specified way to make an image.
FY 2027 changes: The FY 2027 ICD-10-PCS update, effective October 1, 2026, added 4 codes in this body system. Table with changes: B85 Other Imaging.
Questions About This Page
How many codes are in the B8 body system?
The B8 body system contains 56 ICD-10-PCS codes in FY 2027, organized into 5 root operations. 51 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.
