§ 81.20 - Required use of NIOSH-IREP.
(a) NIOSH-IREP is an interactive software program for estimating probability of causation for covered employees seeking compensation for cancer under EEOICPA, other than as members of the Special Exposure Cohort seeking compensation for a specified cancer.
(b) DOL is required to use NIOSH-IREP to estimate probability of causation for all cancers, as identified under §§ 81.21 and 81.23.
§ 81.21 - Cancers requiring the use of NIOSH-IREP.
(a) DOL will calculate probability of causation for all cancers using NIOSH-IREP.
(b) Carcinoma in situ (ICD-10-CM codes D00-D09), neoplasms of uncertain behavior (ICD-10-CM codes D37-D44 and D48), and neoplasms of unspecified nature (ICD-10-CM code D49) are assumed to be malignant, for purposes of estimating probability of causation.
(c) All secondary and unspecified cancers of the lymph node (ICD-10-CM codes C77 and C7B.01) shall be considered secondary cancers (cancers resulting from metastasis of cancer from a primary site). For claims identifying cancers of the lymph node, Table 1 in § 81.23(a) provides guidance for assigning a primary site and calculating probability of causation using NIOSH-IREP.
§ 81.22 - General guidelines for use of NIOSH-IREP.
DOL will use procedures specified in the NIOSH-IREP Operating Guide to calculate probability of causation estimates under EEOICPA. The guide provides current, step-by-step instructions for the operation of IREP. The procedures include entering personal, diagnostic, and exposure data; setting/confirming appropriate values for variables used in calculations; conducting the calculation; and, obtaining, evaluating, and reporting results.
§ 81.23 - Guidelines for cancers for which primary site is unknown.
(a) In claims for which the primary cancer site cannot be determined, but a site of metastasis is known, DOL will calculate probability of causation estimates for various likely primary sites. Table 1 of this paragraph (a) indicates the primary cancer site(s) DOL will use in NIOSH-IREP when the primary cancer site is unknown.
Table 1 to Paragraph (a) Primary cancers (ICD-10-CM codes) for which probability of causation is to be calculated, if only a secondary cancer site is known. “M” indicates cancer site should be used for males only, and “F” indicates the cancer site should be used for females only.Secondary cancer

(b) DOL will select the site producing the highest estimate for probability of causation to adjudicate the claim.
§ 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.
§ 81.25 - Guidelines for claims including two or more primary cancers.
For claims including two or more primary cancers, DOL will use NIOSH-IREP to calculate the estimated probability of causation for each cancer individually. Then DOL will perform the following calculation using the probability of causation estimates produced by NIOSH-IREP:
Equation 1 Calculate: 1−[{1−PC3 Evaluating Equation 1 based on the individual upper 99th percentiles of PC
