In CPT coding, what does the -RT modifier indicate?

• A. Left eye
• B. Right eye
• C. Indicates the right eye; denoted by -RT
• D. Bilateral

Answer: (C)

In CPT coding, modifiers add specific details about how a service was performed. The -RT modifier is a laterality indicator used when a procedure is done on one eye. It specifies the right eye, distinguishing it from the left eye (-LT) and from bilateral situations (which use a bilateral code or the -50 modifier, depending on payer rules). So the modifier conveys that the service was performed on the right eye.
