OK, my theory was wrong. A bit of searching in German threw up this official list of Wehrmacht medical codes:
Official list of Wehrmacht medical codes
It explains the letters at the top. They have to do with how long (if at all) the defect will render the soldier unfit for service:
A & B -> kriegsverwendungsfaehig (fit for combat)
Z -> zeitlich untauglich (temporarily unfit)
L -> bedingt kriegsverwendungsfaehig (fit for limited duty)
U -> arbeitsverwendungsfaehig (fit for labour duty)
vU -> wehruntauglich (unfit for military service)
Really pleased I stumbled across this.
