About the C8 Body System
The ICD-10-PCS root operation for the Eye within the Nuclear Medicine section is represented by code C8, which involves diagnostic imaging techniques using radioactive materials. This operation focuses on capturing images of eye structures by detecting radioactive emissions.
Planar Nuclear Medicine Imaging, coded as C81, exemplifies this operation by introducing radioactive substances into the body to create single-plane images. These images help visualize physiological functions of the eye by mapping the distribution of these materials. This method provides valuable functional information that complements traditional anatomical imaging. Utilizing such specific nuclear medicine eye codes allows precise documentation of advanced diagnostic procedures targeting the eye, crucial for clinical evaluation and treatment planning.
Questions About This Page
How many codes are in the C8 body system?
The C8 body system contains 8 ICD-10-PCS codes in FY 2026, organized into 1 root operations. 6 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.
