Explanation:
The development of the fetus is divided into three periods, established by most embryologists: pre-embyonic period, which goes from fertilization to the second week of development, embryonic period, which goes from the third week to the eighth week, and the fetal period, which goes from from the third month until the end of pregnancy.

Medical coding involves front office administrators, such as receptionists, as well as back office staff, including the medical biller and coder. It is important to understand every step of this process if you intend to pursue a career in medical billing and coding. For the purposes of this lesson, we will cover the end-to-end process of medical billing as a whole, and not just the responsibilities of the biller and coder.
The primary job of medical billing specialists is to:
Understand each individual’s responsibility for payment, as they may differ from patient to patient
Evaluate and analyze insurance coverage and medical charges, and prepare accurate billing forms
Collect accurate payments from insurance plans and/or individual patients
These three primary tasks require many specific responsibilities within the medical billing process. In this course we will break down these responsibilities into a series of steps that begins when a patient schedules an appointment and ends when reimbursement is collected from the insurance company and/or patient.
