I'm hearing rumblings of changes at IMSS. To wit, we are no longer covered for things like knee replacements, cataract surgery, and more. Even though my payment sheet (which I got two weeks ago) is stamped "Sin restricciones" or something similar, I'm hearing that we are covered only for emergency. I'm going in for shoulder surgery in a few weeks, so I guess I'll find out, but I'm just wondering...
