§81.23. Guidelines for cancers for which primary site is unknown.
42 C.F.R. § 81.23
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.
DOL will select the site producing the highest estimate for probability of causation to adjudicate the claim.
