About the 0F Body System
These medical and surgical codes cover procedures on the liver, gallbladder, pancreas and their named ducts. The body-part character distinguishes sites such as the liver’s right and left lobes and the common and accessory pancreatic ducts.
Some procedures remove part or all of a body part, destroy tissue, or break up or remove solid matter. Others drain fluid or gas, widen or narrow a passage, close it completely, or reroute its contents. The tables also cover dividing a body part, freeing it from a constraint, and inspecting it. Device procedures put in, change, remove or correct a device. Other procedures restore, move or reattach a body part, or put in material to replace or reinforce it. Transplantation places a living body part from another individual or animal where it takes the place of a similar body part. The index term cholecystectomy means removal of the gallbladder.
FY 2027 changes: The FY 2027 ICD-10-PCS update, effective October 1, 2026, added 20 codes in this body system. Table with changes: 0F9 Drainage.
Questions About This Page
How many codes are in the 0F body system?
The 0F body system contains 1,963 ICD-10-PCS codes in FY 2027, organized into 24 root operations. 1,939 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.
