About the 09 Body System
These medical and surgical codes cover procedures on the ear, nose and sinuses, including the ear canal, eardrum, nasal septum and named sinuses. The body-part value identifies the site and, for many ear and sinus sites, the right or left side.
The tables distinguish procedures that remove part or all of a body part, pull out tissue, or take out solid matter. Others drain fluid or gas, widen an opening, divide or destroy tissue, or stop acute bleeding. Procedures can also repair, reinforce, replace, move or reattach a body part, or free it from a physical constraint. Device procedures insert, change, remove or correct a device. Inspection explores a body part by sight or touch; bypass changes the route through a tubular body part.
Questions About This Page
How many codes are in the 09 body system?
The 09 body system contains 2,192 ICD-10-PCS codes in FY 2027, organized into 23 root operations. 2,169 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.
