ICD-10-PCS 00K Medical and Surgical: Central Nervous System and Cranial Nerves Map

The ICD-10-PCS root operation Map (code 00K) refers to the process of identifying the functional areas, pathways, or neural networks within the central nervous system and cranial nerves. It is used to create detailed representations of brain structures without performing resection or destruction.

This Medical and Surgical operation focuses on mapping specific brain regions such as the cerebral hemisphere, basal ganglia, thalamus, hypothalamus, pons, cerebellum, and medulla oblongata. The procedure can be performed through various approaches including open, percutaneous, percutaneous endoscopic, and even an external approach using connectomic analysis. For example, code 00K00ZZ denotes an open approach to map the brain, whereas 00K04ZZ indicates a percutaneous endoscopic mapping of the brain. Accurate coding of these procedures is essential for documenting advanced functional brain assessments used in surgical planning or neurological evaluation.

List of ICD-10-PCS codes used to specify 00K - Map (locating the route of passage of electrical impulses and/or locating functional areas in a body part). There are a total of 26 procedure codes in this section.
