Primary Care physicians (PCP) treat patients with all types of acute physical, mental, and chronic ailments and diseases. The patients form a wide range of patients; people of all demographics, socioeconomic groups, and so on. PCPs are thus expected to have thorough knowledge in multiple areas. The versatility of the physician ranges from seemingly simpler ailments like treating a cold to giving vaccinations to providing healthcare tips like the bane of smoking. Such a variety of treatments needs physicians to be well-versed in carrying out appropriate billing for getting reimbursements.
