A gold color metal and enamel device 1 3/16 inches (3.02 cm) in height overall consisting of a gold Philippine sun within a blue disc centered upon a blue Maltese cross with gold rays between the arms and charged with three small red Greek crosses, two placed diagonally between the upper arms of the cross and the third centered upon the outer edge of the lower vertical arm, all enclosed by a maroon scroll with white reversed disc curving around the bottom with two folds at either side ending at the lateral arms of the cross and inscribed in gold with the words "HEALTH IN READINESS."
Maroon and white are the colors used for the Army Medical Department. The Maltese cross, a symbol of the ancient order of Knights Hospitallers, and the rays issuing from it refer to the life-sustaining purpose of the practice of medicine. The cross further alludes to the crest of the coat of arms of the Province of Queensland, Australia, where the predecessor Hospital was located during its initial World War II service. The three smaller crosses indicate the campaign participation credits earned by the predecessor unit during that war, and the gold sun on the blue disc at center signifies the award of the Philippine Presidential Unit Citation.
The distinctive unit insignia was originally approved for the 810th Station Hospital on 22 April 1974. It was redesignated for the 810th Field Hospital with the description and symbolism revised on 6 July 1994.
