Preliminary questions [36995]

36789

there is some evidence that cumulative exposure to benzene may be a factor in the development of the condition under consideration.

37021 — the veteran has established the causal connection between cumulative exposure to benzene and VEA service for the clinical onset of myelodysplastic disorder.

37022 — the veteran has established the causal connection between cumulative exposure to benzene and operational service for the clinical onset of myelodysplastic disorder.

or

37023 — the veteran has established the causal connection between cumulative exposure to benzene and eligible service for the clinical onset of myelodysplastic disorder.

Clinical onset and operational service [37022]

36793 the veteran has received greater than 20 ppm-years of cumulative exposure to benzene before the clinical onset of the condition under consideration.

37025

where the veteran received greater than 20 ppm-years of cumulative exposure to benzene before the clinical onset of the condition under consideration, the first exposure occurred at least five years before the clinical onset of the condition under consideration.

36795

operational service made a material contribution to the veteran receiving greater than 20 ppm-years of cumulative exposure to benzene before the clinical onset of the condition under consideration, where the first exposure occurred at least five years before the clinical onset of the condition under consideration.

Clinical onset and eligible service [37023]

36794

the veteran has received greater than 40 ppm-years of cumulative exposure to benzene before the clinical onset of the condition under consideration where the clinical onset occurred within thirty years of that exposure.

37026

where the veteran received greater than 40 ppm-years of cumulative exposure to benzene before the clinical onset of the condition under consideration and the clinical onset occurred within thirty years of that exposure, the first exposure occurred at least ten years before the clinical onset of the condition under consideration.

36796

eligible service made a material contribution to the veteran receiving greater than 40 ppm-years of cumulative exposure to benzene before the clinical onset of the condition under consideration where the clinical onset occurred within thirty years of that exposure and where the first exposure occurred at least ten years before the clinical onset of the condition under consideration.
