tresho writes to tell us that virtual doctors visits seem to be on the rise. A new service, most recently deployed in Texas, from "NowClinic" is allowing doctors to make virtual house calls and prescribe anything short of controlled substances. "For $45, anyone in Texas can use NowClinic, whether or not they are insured, by visiting NowClinic.com. Doctors hold 10-minute appointments and can file prescriptions, except for controlled substances. Eventually they will be able to view patients’ medical histories if they are available. The introduction of NowClinic will be the first time that online care has been available nationwide, regardless of insurance coverage."
