Some of the largest U.S. insurers including Aetna and Cigna are beginning to reimburse physicians for online patient visits, a trend experts say could become more popular, the Los Angeles Times reports. On average, online health care services, which are considered most appropriate for follow-up consultations, treatment for minor ailments and periodic checkups that do not require in-person office visits, cost roughly the same as a regular office visit. Advocates for online physician visits say they increase care access and patient satisfaction, while critics of the practice, including some physicians, say they could lead to errors and raise some ethical questions. Other experts add that online visits may not reduce costs because the technology could cause patients to seek care more often, the Times reports. Meanwhile, Medicare, which is rakes in roughly half of the country's physician bills, does not reimburse for physician e-mail, and several small insurers recently stopped reimbursing for online physician consultations because so few members used the service (Costello, Los Angeles Times, 2/4/08).
