Medical care rendered not for a specific complaint but focused on prevention and early-detection of disease. This type of care is best exemplified by routine examinations and immunizations. Some health insurance plans limit coverage for preventive care services, while others encourage such services. Note that well-baby care, immunizations, periodic prostate exams, pap smears and mammograms, though considered preventive care, may be covered even if your health insurance plan limits coverage for other preventive care services.
