This clinical guideline defines accepted indications and required evidence sources for Erythropoiesis Stimulating Agents (ESAs) including epoetin alfa, darbepoetin alfa, epoetin beta, and biosimilars. Covered conditions include anemia of chronic kidney disease (CKD), chemotherapy-induced anemia (CIA) in patients with solid tumors or non-myeloid malignancies receiving myelosuppressive chemotherapy without curative intent, and lower-risk myelodysplastic syndrome (MDS) (IPSS Low and INT-1).
The guideline specifies clinical thresholds and documentation requirements such as: CKD defined as GFR < 60 ml/min for ≥ 3 months; iron status with serum ferritin ≥ 30 ng/mL and/or transferrin saturation (TSAT) ≥ 20% within the prior 12 months; hemoglobin (Hgb) criteria for initiation and continuation (CKD initiation Hgb < 10 g/dL; CKD continuation Hgb ≤ 11 g/dL); CIA baseline Hgb < 10 g/dL or HCT < 30; MDS serum erythropoietin ≤ 500 mU/mL, MDS initiation Hgb < 10 g/dL or HCT < 30, MDS continuation Hgb ≤ 11 g/dL, and bone marrow blasts < 10% for eligible MDS use. CIA eligibility also requires chemotherapy ongoing or completed ≤ 8 weeks prior and risk of RBC transfusion within 30 days.
Evidence relied upon to support ESA use must include one of the following: FDA-approved product labeling, CMS-recognized compendia, NCCN or ASCO clinical guidelines, or peer-reviewed literature that meets CMS Medicare Benefit Policy Manual Chapter 15 standards. The policy lists applicable HCPCS/J and Q codes for ESAs and specifies lines of business applicability (Commercial, Exchange/Marketplace, Medicaid; Medicare Advantage unchecked).
Warnings and clinical rationale are summarized from product labeling and safety guidance, including boxed warnings about increased risks of death, serious cardiovascular events, thromboembolism, and increased tumor progression or shortened survival in some cancers; recommendation to use the lowest effective dose to avoid RBC transfusion and to avoid ESA use in curative-intent chemotherapy and certain myeloid malignancies. The policy status is CURRENT with recent administrative updates (template conversion and references updated April 2025) and a material update to exclusion criteria in June 2025.
