T

Telemedicine

Medical or other health services given to a patient using a communications system (like a computer, phone, or television) by a practitioner in a location different than the patient's.

Tiers

Groups of drugs that have a different cost for each group. Generally, a drug in a lower tier will cost you less than a drug in a higher tier.

TTY

A TTY (teletypewriter) is a communication device used by people who are deaf, hard-of-hearing, or have severe speech impairment. People who don't have a TTY can communicate with a TTY user through a message relay center (MRC). An MRC has TTY operators available to send and interpret TTY messages.
