• Correct Modifiers for Bilateral Billing


    Question: What is the appropriate way to bill a bilateral injection and drug?

    Answer: Medicare states that you bill bilateral procedures on one line with modifier -50.

    • 67028 -50, 1 unit and double the amount. Submit with the bilateral diagnosis.
    • For the drug, double the units and bill the bilateral diagnosis.

    Commercial payers may want two separate lines for both. In that case, bill the eye modifier that goes along with the correct laterality.
