Nebulizer Policy Article Update – Required Modifiers

The Nebulizer Policy Article has been revised. For dates of service on or after February 1, 2026, suppliers must add one of these modifiers (KX, GA, or GZ) to claims for ALL:

  • Nebulizers
  • Nebulizer related drugs
  • Nebulizer related supplies

If you submit a claim without one of these modifiers, we will reject it for missing information.
