Documentation Required

This article provides billing and coding guidelines that complement Local Coverage Determination (LCD) L37176 for White Cell Colony Stimulating Factors; refer to LCD L37176 for specific coverage criteria, indications, and limitations.

Documentation of a prior, medically necessary allogeneic bone marrow transplantation or peripheral stem cell transplantation (e.g., transplant operative report, discharge summary, transplant center records).

Clinical documentation supporting the indication for DLI (diagnosis/problem list with corresponding ICD-10 code among covered diagnoses such as C91.00-C91.02, C92.00-C92.02, C92.10-C92.12, or documentation of transplant status Z94.81 / Z94.84).

Medical records demonstrating that the requested DLI is not one of the policy-listed experimental/investigational uses (e.g., not CAR-modified donor lymphocytes, not G-CSF-stimulated DLI for the purpose stated, not intrathecal DLI, not ECP-treated donor cells for pre-transplant organ tolerance, etc.).

If applicable, documentation of prior treatments and rationale for DLI as salvage therapy or for graft-versus-leukemia effects (e.g., prior relapse after allo-HCT, prior therapies tried and outcomes).

Key Coverage Criteria

Medically necessary use of Leukine, Neupogen, Nivestym, Nypozi, Releuko, and Zarxio for bone marrow/stem cell transplant indications when: (a) non-myeloid malignancies with myeloablative chemotherapy followed by BMT; or (b) mobilization of hematopoietic progenitor cells into peripheral blood for leukapheresis; or (c) PSCT after myeloablative chemotherapy.
ICD-10 codes covered if selection criteria are met: Z94.84 (Stem cells transplant status).
ICD-10 codes covered if selection criteria are met: C92.10 - C92.12 (Chronic myeloid leukemia, BCR/ABL-positive).
ICD-10 codes covered if selection criteria are met: Z94.81 (Bone marrow transplant status).
Donor lymphocyte infusion (DLI) is considered medically necessary for persons who have a prior, medically necessary allogeneic bone marrow or peripheral stem cell transplantation.
DLI for treatment/management related to the following covered ICD-10 diagnoses when selection criteria are met: C91.00 - C91.02 (Acute lymphoblastic leukemia [ALL]).
