HCPCS Code Q0138: Injection, Ferumoxytol, For Treatment of Iron Deficiency Anemia, 1 mg (non-ESRD use)

Q0138 is specifically designated for ferumoxytol administration in patients with iron deficiency anemia who do not have end-stage renal disease (non-ESRD use). Q0139 covers the same drug and dosage but applies to patients with ESRD who are receiving dialysis treatments.

Intravenous (IV) iron infusion is generally covered by insurance, including Medicare, when medically necessary for conditions such as iron deficiency anemia unresponsive to oral iron, but coverage depends on the payer’s specific policies and documentation requirements.

The CPT code commonly used for IV iron infusion administration is 96365 for the initial hour of therapeutic intravenous infusion, with additional codes (e.g., 96366) for subsequent hours if applicable, while the specific iron product itself is billed separately using the appropriate HCPCS code.
