What is a key difference between codes 66850 and 66984?

The key difference between the codes 66850 and 66984 lies in the type of procedures they describe regarding cataract surgery. The code 66850 specifically refers to the procedure for the extraction of cataract using an intracapsular technique, which does not involve the replacement of the lens. Therefore, lens implantation is not included in this code.

In contrast, the 66984 code is used for cataract extraction that typically includes lens replacement, specifically for extracapsular surgery, which is a more advanced method that involves the removal of the cataract while placing an intraocular lens (IOL) during the same procedure.

Understanding this distinction is crucial for correct coding and billing in ophthalmology, as it affects surgical reimbursements and ensures accurate patient records. The focus on lens implantation in the definition of code 66984 establishes its difference from 66850, affirming that the correct answer highlights the lack of lens replacement included in the 66850 code.
