(A patient’s left eye is damaged beyond repair due to a work injury.

This question is testing recognition of amaxillofacial prosthetic servicerather than an ophthalmology procedure code. The vignette describesfabrication of a prosthesis using silicone materialswithmodificationsintended to restorecosmetic appearanceafter loss/damage of an eye. Among the provided options,21086is the CPT code that corresponds to fabrication of afacial prosthesis(commonly silicone-based) with the intent of external restoration. The other codes in this small cluster represent different facial/craniofacial repair or prosthetic services and do not match silicone prosthesis fabrication described in the scenario. CPC exam technique: focus on the key nouns—“fabricates a prosthesis,” “silicon materials,” “cosmetic appearance restoration”—which point away from repair codes and towardprosthetic fabrication. Also note the question is not about insertion of an ocular implant during enucleation/evisceration, but about crafting an external prosthetic device. Therefore, the correct selection is21086.
