No HPI must be all three across the board and the lowest will determine the level of history. You visit level however, if this is a New patient is dependent on all three key components, History, exam, decision making, where established patient is 2 out of 3. IN your hisotry, if you have HPI that is extended, with no ROS and comprehensive PFSH then you have a focused history. Remeber there are actuall 4 components of HISTORY, that is :
chief compalint - must be stated or no history can be counted
HPI - to be extended must contain four elements of : location, quality, severity, modifying factors, associated signs and symptoms,etc...
ROS - which goes by body systems, 0 is focused, 1 is expanded, 2-9 is detailed, >9 is comprehensive
PFSH - which is patient medical hx, pertinent family hx, and social hx. 0 is focused, or expanded, 1 or 2 is detailed and 3 is comprehensive.
The vitals do not count as ROS, they are a part of exam. so it looks like you probably have a focused hx or an expanded focused at best.
