  We combine results from CDF and D0's direct searches for the standard model
(SM) Higgs boson (H) produced in ppbar collisions at the Fermilab Tevatron at
sqrt{s}=1.96 TeV, focusing on the decay H\rightarrow\gamma\gamma. We compute
upper limits on the Higgs boson production cross section times the decay
branching fraction in the range 100<m_H<150 GeV/c^2, and we interpret the
results in the context of the standard model. We use the MSTW08 parton
distribution functions and the latest theoretical cross section predictions
when testing for the presence of a SM Higgs boson. With datasets corresponding
to 7.0 fb-1 (CDF) and 8.2 fb-1 (D0), the 95% C.L. upper limits on Higgs boson
production is a factor of 10.5 times the SM cross section for a Higgs boson
mass of 115 GeV/c^2.
