About the 00B Code Range

The ICD-10-PCS root operation Excision (00B) involves the surgical removal of a portion of a body part. In the Medical and Surgical section, specifically targeting the Central Nervous System and Cranial Nerves, this operation removes tissue for therapeutic or diagnostic purposes.

This operation is performed on various neural structures such as the Brain, Cerebral Meninges, Dura Mater, and multiple cranial nerves like the Optic Nerve and Facial Nerve. Approaches include Open, Percutaneous, and Percutaneous Endoscopic. For example, the code 00B00ZZ denotes the excision of brain tissue via an open approach, while 00B83ZX represents a diagnostic excision of the basal ganglia using a percutaneous approach. These codes facilitate precise documentation of the excision procedure related to specific central nervous system components, critical for accurate procedural reporting and clinical communication.
