A model to study the absorption and propagation of high energy photons through the radiation field of accretion disks is presented. The model indicates that this absorption process is important for gamma-rays with energies between 100 GeV and a few TeV produced near the co-rotation radius of X-ray binary systems with pulse periods of about 1 s. The redistribution of the primary energy into other photons through electromagnetic cascades is shown to diminish this absorption. The overall process implies a particle luminosity in excess of the Eddington limit for spherical accretion but not unlikely to be produced under other geometries, like accretion columns. A plausible qualitative explanation of conflicting observations of TeV gamma-rays from X-ray binaries is provided by the model; however, a quantitative analysis does not fully explain the discrepancies between imaging and nonimaging observations of 4U 0115 + 63 and Hercules X-1.
