Which CPT code indicates a right-eye laser capsulotomy with a right-eye modifier?

• A. 66821-LT
• B. 66821-RT
• C. 66821
• D. 66821-R

Answer: (B)

Billing a laser capsulotomy correctly requires pairing the correct eye-specific modifier with the CPT code. The CPT code for a laser capsulotomy is 66821. When the procedure is performed on the right eye, you add the right-eye modifier RT, giving 66821-RT. This clearly indicates which eye was treated. Reporting 66821 alone misses the eye, 66821-LT would indicate the left eye, and 66821-R is not a valid modifier.
