| C91.00 | Acute lymphoblastic leukemia not having achieved remission | Use for newly diagnosed or active ALL without remission. | - Bone marrow blasts ≥20% - Flow cytometry confirming B/T-cell lineage |

Possible reason: One claim defines an in-remission code whereas the other defines a not-in-remission code, so they assert different remission statuses for the same disease category.
