About the 00T Code Range
The ICD-10-PCS root operation Resection (Character 00T) refers to the surgical removal, in part or whole, of a body part. This operation is categorized under the Medical and Surgical section, specifically targeting the Central Nervous System and Cranial Nerves.
Resection involves excising a portion or the entirety of an anatomical structure, often to treat disease or injury. For example, the codes demonstrate different approaches to removing part of the Cerebral Hemisphere: an Open Approach (00T70ZZ), a less invasive Percutaneous Approach (00T73ZZ), and a minimally invasive Percutaneous Endoscopic Approach (00T74ZZ). These distinctions help accurately document the extent and method of resection, which is essential for clinical clarity and procedural coding.
