Anatomical loss of one hand and loss of use of one foot (DC 5104)
This diagnostic code covers the specific combination of losing one complete hand (either through amputation or total loss of function) plus losing the use of one foot (meaning the foot is still there but doesn't work properly). This is a fixed rating situation - the VA doesn't use percentage ranges but assigns a set rating percentage based on this exact combination of losses. You'll need to look at the amputation rating table in 38 CFR § 4.71a to find your specific rating, which will be quite high given the severity of losing both a hand and the use of a foot.
