The correct answer is A. Immediately. Under accident and health insurance provisions, newborn children must be covered from the moment of birth under an existing health insurance policy that provides dependent coverage. This requirement ensures that medical expenses related to the newborn’s birth and any immediate medical needs are eligible for coverage without delay. The rule is designed to protect infants during the critical period immediately following birth, when medical care is commonly required.

Although coverage begins immediately at birth , most policies and state insurance rules allow the policyholder a limited period—often 30 or 31 days —to formally notify the insurer and add the newborn as a dependent while maintaining continuous coverage from birth. If the policyholder completes the enrollment within that period and pays any additional premium required, coverage remains effective retroactively to the date of birth.

Therefore, the key concept tested in accident and health licensing materials is that a newborn child must be covered immediately upon birth , even though administrative enrollment to formally add the child may occur within a specified time period afterward. This makes “Immediately” the correct answer.
