I think most schools I looked at when applying did. I seem to recall seeing specific AP policies on the admissions pages of schools. You may just have to dig a little deeper. If that's not helpful, you can always call admissions at your top schools at least and ask. All the admissions staff I talked to were friendly and eager to help.
If you're talking about AP English and Calc, you'll have an easier time using those classes than for AP Bio or Chem. I recall seeing one school that required science classes be taken in undergrad versus AP credit.
AP credits are usually considered very low when applying to medical schools because they expect you to take college courses for your prerequisites such as Biology, Physics. However, if you got your AP credit from psychology, I don't think it matters but I would call the school just in case.
