About 00504Z3

00504Z3 is the ICD-10-PCS code for a destruction procedure on the brain using a percutaneous endoscopic approach (qualifier: laser interstitial thermal therapy). In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.

For a different body part, codes include 005W4Z3 (cervical spinal cord), 005X4Z3 (thoracic spinal cord) and 005Y4Z3 (lumbar spinal cord).
