CPT code 66840 is used for what type of procedure?

CPT code 66840 is specifically used for the removal of lens material through an aspiration technique, which involves suction to extract the lens material when it is opacified, typically in cases such as a dislocated lens or one that has cataracted. This procedure is often performed when the cataract has been fragmented or the lens is not able to be removed through traditional techniques like phacoemulsification.

In this context, the aspiration technique indicates that the physician is using a device to suck out the remaining lens fragments rather than using incisional techniques or other methods. The choice of aspiration is particularly relevant when addressing specific conditions where traditional extracapsular techniques may not be suitable or effective.

The other options relate to different surgical techniques used in ophthalmic procedures. Phacoemulsification is a commonly used technique (indicative of option A), while the removal of intracapsular lens material pertains to a completely different coding situation (related to option C). Similarly, option D concerning pars plana approaches pertains to vitreoretinal procedures rather than those specifically for cataract extraction. Therefore, code 66840 accurately reflects the aspiration technique for lens material removal.
