Nervous System (X0) ICD-10-PCS
The X0 body system covers New Technology procedures on nervous system, with 18 ICD-10-PCS codes across 3 root operations, 12 of them billable in fiscal year 2026. Each root operation defines a distinct procedural objective, and the info icons show the official definition with a preview of the codes inside.

About the X0 Body System
The ICD-10-PCS root operations within the Nervous System under the New Technology section include targeted procedures such as Destruction, Insertion, and Other Procedures. These operations focus on innovative methods to treat or manage neurological conditions.
Destruction involves the physical eradication of all or part of a nervous system structure using energy, force, or destructive agents, aimed at eliminating problematic tissue. An example is the use of laser or radiofrequency energy to ablate nerve tissue. The Insertion root operation refers to placing a nonbiological device that monitors or supports nervous system function without replacing any body part—such as implanting a neurostimulator to modulate nerve activity. Lastly, Other Procedures encompass various advanced techniques designed to remediate or cure neurological diseases using novel approaches. These codes under the New Technology classification enable precise documentation of emerging nervous system treatments, critical for accurate coding and clinical communication.
Questions About This Page
How many codes are in the X0 body system?
The X0 body system contains 18 ICD-10-PCS codes in FY 2026, organized into 3 root operations. 12 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.
