State legislation determines the restrictions and often, the reimbursement rates for telemedicine services administered in that state. For instance, any state that has passed a telemedicine parity law has mandated that private payers in that state to reimburse telemedicine visits at the same rate as a comparable in-person visit. While a majority of states have now passed telemedicine parity laws, changing state legislation is often a time-consuming, unwieldy process and can have a huge impact on the telemedicine practices in that state.

Telepathology has been successfully used for many applications including the rendering histopathology tissue diagnoses, at a distance, for education, and for research. Although digital pathology imaging, including virtual microscopy, is the mode of choice for telepathology services in developed countries, analog telepathology imaging is still used for patient services in some developing countries.

Telemedicine is an important and quickly growing component of healthcare delievery in the United States.  There are currently about 200 telemedicine networks, with 3,500 service sites in the US.  In 2011 alone the Veterans Health Administration delivered over 300,000 remote consultations using telemedicine. More than half of all U.S. hospitals now use some form of telemedicine.
Telecare is the term that relates to technology that enables patients to maintain their independence and safety while remaining in their own homes. This technology includes mobile monitoring devices, medical alert systems, and telecommunications technology like computers and telephones. Continuous remote monitoring of patients enables telecare to track lifestyle changes over time as well as receiving alerts relating to real-time emergencies.
Policies and regulations in the telemedicine arena can be confusing for providers, vendors, and payers. Organizations interested in implementing telemedicine should be familiar with the laws in their state. For example, some states require informed consent from patients, while others do not. Some payers may not pay the same rate for telemedicine services as they do for in-person services. Practices should identify how providers will be paid, as some organizations seek grant funding.
Today, 95 percent of Americans own cell phones and 77 percent own smartphones. These and other mobile devices can be leveraged to promote better health outcomes and increased access to care. mHealth or mobile health refers to healthcare applications and programs patients use on their smartphones, tablets, or laptops. These applications allow patients to track health measurements, set medication and appointment reminders, and share information with clinicians. Users can access hundreds of mHealth applications including asthma and diabetes management tools as well as weight loss or smoking cessation apps. Additionally, mobile devices allow users to schedule appointments and communicate with providers via video conference and text message.

1. The doctor writes you a prescription. In-person, this can mean a handwritten prescription or a digital prescription sent directly to a pharmacy. Prescriptions can be sent to a retail pharmacy, mail-order pharmacy, or pharmacy inside your doctor’s office. Online doctors only have the digital option and will likely send the prescription to a retail pharmacy in your area.
