Ophthalmic Coding Specialist Practice Test

What is the main function of CPT code 66850?

1. Intracapsular removal of lens material

2. Phacoemulsification with aspiration

3. Phacofragmentation technique for lens material removal

4. Posterior capsulotomy

The correct answer is: Phacofragmentation technique for lens material removal

CPT code 66850 specifically pertains to the procedure known as phacofragmentation. This technique involves dividing the lens material into smaller pieces, which can then be removed through suction. Phacofragmentation is generally associated with cataract surgery, where the cataractous lens is fragmented to facilitate its removal. The significance of this code lies in its precise description of the surgical approach rather than a general procedure. Other methods of lens removal, such as intracapsular removal or phacoemulsification, are classified under different codes in the CPT coding system due to the differences in techniques and equipment used. For instance, phacoemulsification utilizes ultrasonic vibrations to break up the lens before aspiration, resulting in a distinct CPT code for that specific process. In addition, posterior capsulotomy, which involves creating an opening in the posterior capsule of the lens, serves a different purpose and clinical indication compared to the phacofragmentation described by this code. Understanding these distinctions ensures accurate coding and appropriate reimbursement for the specific procedures performed.
