In the 2002-2003 MSAR, pages 16,17,18, Table 1B, there is a rundown on all combined degree programs other than MD/PhD. MD/JD programs are included.
Another way to earn both degrees is to go, seriatum, to law school and medical school.
Law schools are 3 years (full time) and rarely have specific admission requirements other than a college degree and the LSAT.
Because medical schools have many specific admission requirements and the progression from 1st year med student to licensed physician usually takes a minimum of 7 years, if you go this route it might be wiser to go to law school first, take the premed requirements in a postbac program and then apply to medical school. It has been done before and in either order.
