Answer: Code 95933 (orbicularis oculi [blink] reflex, by electrodiagnostic testing) uses the term oculi, which is the genitive and plural of oculus and refers to both eyes. HCFA defines this as a bilateral procedure. The test should be reported once. Modifier -50 (bilateral procedure) should only be appended to a code representing a unilateral procedure that was performed bilaterally.
