    According to insurance companies, what is the definition of a “minor” procedure? Is it one that is performed: a) in a short amount of time, b) in an office, or c) by teenage prodigy Douglas “Doogie” Howser, MD. The answer, of course, is none of the above. A minor procedure is one that has a zero- or 10-day global period. Now that you’re warmed up, try tackling this quick quiz.

    Q9. Pterygium excision with graft (CPT code 65426) is performed using amniotic membrane (65780). You should code:

    a) For the pterygium excision only, since the graft is bundled in the Correct Coding Initiative..
    b) For amniotic graft only, since it has the highest allowable.
    c) 65780–eye modifier and 65426–59–eye modifier.

    Answers: Q1—b) False. They have their own fee schedule, but no global period. Q2—a) True. But only if medically indicated. Q3—b) False. No matter how many times the procedure is repeated for the same indication, only one claim is submitted. Q4—b) False. The zero indicates the procedure is payable per session, not per eye. Q5—a). Q6—a). Q7—b) False. Fraud, not abuse, involves intent. Q8—c) Fundus photography has inherently bilateral payment. Fluorescein angiography is payable per eye when medically necessary. When using modifiers –RT and –LT, there is no need to add –50 since doing so would indicate the patient had three eyes tested. Q9—a). The transplant is not separately billable per the CCI.
