What term is used to describe a physician, specialist or any person that provides medical care?

The term used to describe a physician, specialist, or any person that provides medical care is "provider." This designation encompasses a wide range of healthcare professionals, including doctors, nurses, and other practitioners who deliver medical services to patients. The use of "provider" in healthcare contexts signifies the individual or entity responsible for diagnosing, treating, and managing patients' health concerns. This term is essential in healthcare discussions, particularly in insurance and medical billing, as it distinguishes those who offer healthcare services from those who receive them, namely the patients.

In contrast, the other terms have distinct meanings: a patient is the recipient of medical care, a client typically refers to someone utilizing services in a wellness or alternative care context, and an insurer is a company that provides financial protection against healthcare costs. Understanding these distinctions is crucial in the healthcare field.
