# §81.24. Guidelines for leukemia.

- (a) For claims involving leukemia, DOL will calculate one or more probability of causation estimates from up to three of the four alternate leukemia risk models included in NIOSH-IREP, as specified in the NIOSH-IREP Operating Guide. These include: “Leukemia, all types” (ICD-10-CM codes C91-C95), “acute lymphocytic leukemia” (ICD-10-CM code C91.0), and “acute myelogenous leukemia” (ICD-10-CM codes C92.6 and C92.A).
- (b) For leukemia claims in which DOL calculates multiple probability of causation estimates, as specified in the NIOSH-IREP Operating Guide, the probability of causation estimate DOL assigns to the claim will be based on the leukemia risk model producing the highest estimate for probability of causation.
