(Bloomberg Business) — Julie Moss, a vice president at HBO, had an appointment for a checkup. But instead of hailing cabs and waiting in a doctor's office, she had the doctor come to her.

Actually, a nurse practitioner. She set up a makeshift medical station in Moss's New York office, laying out a bandage, needles, gauze, and other doctorly contraptions on a disposable sheet on a table next to the couch. She began with a finger prick for a cholesterol check. 

The phone rang. Moss, now with a bandage on her index finger, trotted over to take it. It was her boss. While they chatted and scheduled a few meetings, the nurse practitioner ran the blood sample through a reader. After the call, Moss had her blood pressure, temperature, and other vitals checked. The appointment took less than half an hour and would have cost $75, if not for the current promotion that made it free.
