Nebulizer Initial Dispensing Fee Reminder

HCPCS code G0333 is a one-time, lifetime dispensing fee for a beneficiary's initial 30-day supply of covered inhalation drugs. Once G0333 has been billed, any future 30-day dispensing fees must be submitted using Q0513. Billing G0333 again will result in claim denial for incorrect coding. For further information review the Nebulizer Policy Article (A52466).
