Yes, provided your Sim is in the Doctor career then you have the option to come a long. You will also have the option with a pregnant Sim to give birth at the Hospital. The Get to Work Expansion is required.
Just checking you weren't watching a youtube video of someone using Zerbu's Travel to Special Lots Mod; I used it for a while but the amount of staff is very low in comparison to 'usual' but is still working I think. Also, 'Coolspear' over at Sims Asylum made a reworked wormhole that took you 'anywhere' as well. You'd have to check if they are up to date if interested though
Hope this helps..

@Fgrrgreds, you can't get to the hospital lot by the map because the hospital is hidden. Instead, you get there by clicking on the Sim that is in labor. There should be an option to go to the hospital. For people who don't have the Get to Work EP, they will just disappear for a little while and come back with a baby, or have the baby at home. For people who do have the Get to Work EP you will have the option to follow your Sim to the hospital to have the baby, or to have the baby at home.
