With the rules so far, the main benefit of high TL in the field of medicine is Medicinal Slow, which greatly speeds up healing. Secondary benefits include replacement limbs (how are limbs lost in Traveller gameplay anyway? Referee fiat?) and somewhat better Medikits. However, I'd like to imagine that higher TL would be able to provide greatly improved medical care to those who can afford it; maybe you should (for the very least) add a +DM to skill checks and/or to the characteristic points restored for using high TL equipment and facilities?
