Which of the following is not a root operation according to ICD-10-PCS?

In the context of ICD-10-PCS, root operations classify the specific objectives of procedures performed on the body. Each root operation has a defined meaning and corresponds to a unique conceptual action in surgical procedures.

Extraction refers to the removal of a device or prosthesis from a body part, focusing particularly on the act of pulling out or taking something out of the body. Control involves stopping or attempting to stop bleeding, which is critical in various surgical contexts. Removal indicates taking out or off a device, which is closely related to extraction but has a more general scope.

Incision, however, is not recognized as a root operation within the ICD-10-PCS classification. Instead, it serves as a component of other root operations, such as in the case of an incision performed to access a site before carrying out a procedure like excision or repair. The absence of incisional procedures as standalone coding elements distinguishes it from the root operations categorized explicitly by ICD-10-PCS.

Understanding these definitions helps clarify the roles of each term within the coding framework, illustrating why the answer is rooted in the context and established classifications used in ICD-10-PCS.
