The medical field is a large and diverse area of study and practice. It includes many different sub-fields, each with its own specialty and approach to health care. These fields include:
Medicine is the science of healing. It involves a wide range of activities from diagnosing and treating disease to promoting optimal well-being through lifestyle changes. It also includes research into the causes of illness and injury. The core of modern medical care is provided by physicians, who are trained in a number of specialties. In addition to doctors, nurses, paramedics, therapists and technicians play important roles in health care.
A physician’s training and education are highly regulated in most countries, and physicians must be licensed or registered to practice medicine. This ensures that patients are seen by qualified practitioners and that the practices of medicine are guided by sound evidence. It also helps to discourage charlatans and quacks who may attempt to defraud or mislead patients.
When a patient visits a doctor, the first thing that will be reviewed is the medical history. This is vitally important as it often provides the first clues to a diagnosis and can help determine which tests to order in the first place. In addition, the history can help to indicate whether a patient is at higher risk for certain procedures or has any pre-existing conditions that should be taken into account.
During a typical visit, a patient will present with a complaint or problem and the healthcare provider will take a detailed medical history and perform a physical exam. The medical record will then be used to generate a diagnosis and create a treatment plan.
The word “medical” is derived from the Latin verb medicus, meaning “to heal”. Throughout human history, people have striven to understand their bodies and cure disease. The earliest written documentation of a disease process comes from ancient Mesopotamia, where clay tablets bearing cuneiform scripts documenting sick persons and their treatments were found.
While a basic understanding of anatomy and physiology is necessary to fully comprehend medical terminology, learning the vocabulary is not an insurmountable task. Most medical terms can be broken down into three parts: the prefix, root and suffix. The prefix is the initial part of a medical term and usually indicates a location, direction, time, type or quality. The root is the middle portion of a medical term and conveys the primary meaning of the term. The suffix is tacked onto the end of the root and indicates a procedure, function, test or pathology.
Medical coding is the process of reviewing a patient’s complaint, taking their medical history into account and then documenting all aspects of the encounter to be sent to a billing department for payment. This is an important process that requires a significant level of skill and knowledge in order to properly code the patient’s visit and provide accurate information for reimbursement. This information is then used by the payer to determine what services are covered under their insurance policy.
