Walk-in clinics hve already been mentioned, and I second that reply.
Just about any doctor will take cash, but it won't be the same as co-pays with insurance. There are several walk-in clinics in the area, like KW Urgent Care and anplce on 1960 near Papa Murphys. You just need to google Humble or Kingwood family doctors, then call them to ask for their cash price.
Also, I thought Nobama made affordable healthcare available to everyone, that is after everyone working for and paying for company benefits saw their premiums skyrocket and THEIR benefits and access to good healthcare dwindle. 4951
