About 0G5N4Z3

0G5N4Z3 is the ICD-10-PCS code for a destruction procedure on the right inferior parathyroid gland 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.
