Reader Question:

Complete PFSH Required For Observation Services

Question: Is it always required that a family history be documented before assigning code 99220 or 99236 for comprehensive or high complexity observation services?

Answer: You are correct in that the CMS documentation guidelines say that comprehensive observation services, unlike ED E/M, require three of three PFSH elements for the highest level.  Also CPT® includes these elements in the definition of a comprehensive History, which is required for observation codes.

  • Chief complaint;
  • Extended history of present illness; 
  • Review of systems that is directly related to the problem(s) identified in the history of the present illness plus a review of all additional body systems;
  • Complete past, family, and social history

Only the lowest level of observation, codes 99218 or 99234 can be billed with a detailed or comprehensive history and physical exam; but what usually droves the observation choice is the level of medical decision making low, moderate or high.
