Which CPT code refers to laser surgery for treating secondary membranous cataract?

  1. 66820

  2. 66821

  3. 66825

  4. 66830

The correct answer is: 66821

The correct choice refers to the specific procedure of laser capsulotomy, which is utilized to treat secondary membranous cataract, commonly known as posterior capsule opacification (PCO). This condition can develop after cataract surgery when the tissue behind the lens becomes cloudy, necessitating intervention to restore clear vision. The CPT code 66821 is specifically assigned to the use of laser surgery (YAG laser) for the treatment of PCO. This code indicates that a laser is employed to open the opaque capsule, allowing light to reach the retina more effectively, which improves visual acuity. Each of the other codes corresponds to different types of surgical interventions or management of eye conditions. For example, while 66820 also pertains to capsulotomy, it applies to manual procedures rather than laser techniques. The other codes cover various procedures that do not specifically address the treatment of secondary membranous cataract using laser technology. This specificity in coding is vital for accurate reporting and appropriate reimbursement within ophthalmic surgical practices.
