Question: What elements should we look for when selecting the HPI level? Nebraska Subscriber Answer: The history of present illness (HPI) is an element within the history component - one of the three key factors used in selecting the correct level of E/M service. The CPT® 2017 manual defines HPI as "a chronological description of the development of the patient's present illness from the first sign and/or symptom to the present." Obtaining the patient's HPI is an important first step in determining the etiology of a patient's problem, according to Cynthia A. Swanson, RN, CPC, CEMC, CHC, CPMA, senior manager of healthcare consulting for Seim Johnson in Omaha, Nebraska. The HPI information can assist a practitioner in arriving at the patient's diagnosis. The physician will ask the patient to describe his problem, to start the HPI conversation, Swanson says. The physician may ask the patient any one or more of the following questions to get into the HPI discussion: There are two levels of HPI - brief and extended. You tally HPI by reviewing the notes and deciding how many of the following elements the provider reviewed relative to the patient's chief complaint (CC): Brief HPI: With a brief HPI, the documentation would illustrate one to three of the above elements. Extended HPI: With an extended HPI, the documentation would include four or more of the above elements.
