The white cross, symbolic of the healing art, alludes to the Hospital, the torch and rays on the blue base suggested by the State flag of Indiana, referring to the hospital's location. The torch is also emblematic of life, knowledge, service and guidance, the rays symbolizing the power of good, radiation and therapy. The fleur-de-lis and two stars are for the two campaigns, Northern France and the Rhineland, World War II, in which the unit, as the 90th General Hospital, participated. The scarlet arc (reverse of the motto scroll), alludes to the Meritorious Unit Commendation streamer for the European Theater awarded for this service. The motto "SANABUNTUR" ("They Shall Be Restored to Health") reflects the Hospital's mission and dedication. The colors maroon and white are used for the Army Medical Department.
The distinctive unit insignia was originally approved for the 337th General Hospital on 25 July 1969. It was redesignated for the 337th Combat Support Hospital with the description and symbolism revised on 6 July 1994.
