HCPCS Code Q4081: Injection, Epoetin Alfa, 100 Units (For ESRD on Dialysis)

HCPCS code Q4081 is for the injection of epoetin alfa, 100 units, specifically used for patients with End Stage Renal Disease (ESRD) on dialysis.

Retacrit is a biosimilar to epoetin alfa, often used with ESRD diagnosis codes such as N18.6 for End Stage Renal Disease.

Epogen (epoetin alfa) injections for non-ESRD use typically use the HCPCS code J0885 (injection, epoetin alfa, 1,000 units), rather than a CPT code.

Mircera (methoxy polyethylene glycol-epoetin beta) is billed under HCPCS codes like J0881 for injection, but specific billing codes may vary by indication and setting.
