About the C5 Body System
The ICD-10-PCS root operation C5 - Veins pertains to procedures involving nuclear medicine imaging techniques that focus specifically on the venous system. This method uses radioactive materials to visualize veins and assess their condition.
Within the Nuclear Medicine classification, the primary procedure recorded under this root operation is Planar Nuclear Medicine Imaging. It involves introducing radioactive substances into the body, which emit signals captured to create a single-plane image of the veins. The specific code C51 represents this imaging technique. This approach is valuable for diagnosing venous disorders by providing detailed visualization without invasive measures. Correctly assigning this code ensures precise documentation of vein evaluation in nuclear medicine contexts.
Questions About This Page
How many codes are in the C5 body system?
The C5 body system contains 32 ICD-10-PCS codes in FY 2026, organized into 1 root operations. 30 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.
