Not completely but there is the IMLC where if you have a standard license in a member state, and go through credentialing with the IMLC, you can easily get a license in another member state. However the licenses through the compact can have shorter expiration dates. If you move to another state, you need to redesignate your state of principal licensure which means you need to go through the standard process of getting a license in that state. So it really is only meant for locums and other short term positions.

Otherwise, there are not reciprocity agreements for regular permanent licenses. Medical licensing is miserable in many states and yes, you have to start over every time almost. Many states use FCVS, so it is worth it to pay for them to keep your info in perpetuity to use in the future. It actually gets slightly more difficult every time you get a new license because some states will want a continuous record of everywhere you’ve worked since finishing training, explain all gaps of >1 month, and want letters of good standing from everywhere you currently, or have previously, held a license.
Also, every state has different CME requirements on a different timeline/schedule.
