Check your coding against these answers to see where you should focus your E/M education. Answer 1: Yes. Based on E/M guidelines, if a patient's past medical, family and social history (PMFSH) has not changed since a prior visit your otolaryngologist doesn't have to document the information again. He does, however, need to document that he reviewed the previous information to be sure it's up to date and also note in the present encounter's documentation the date and location of the initial earlier acquisition of the PMFSH. Some payers will give no PMFSH credit if you overlook one of these criteria. Both the 1995 and 1997 E/M documentation guidelines include the following: "A ROS and/or a PFSH obtained during an earlier encounter does not need to be re-recorded if there is evidence that the physician reviewed and updated the previous information. This may occur when a physician updates his or her own record or in an institutional setting or group practice where many physicians use a common record. The review and update may be documented by: Answer 2: The key, however, is that you have to use either 1995 or 1997 guidelines for a single encounter. "I have found in my audits that typically, the 1997 documentation guidelines are the most advantageous for otolaryngology practices," says Barbara Cobuzzi, MBA, CPC, CENTC, CPCH, CPC-P, CPC-I, CHCC, president of CRN Healthcare Solutions, a consulting firm in Tinton Falls, N.J. "This is because in the 1995 guidelines, ENT is counted as one organ system, even though the physician is examining three organ systems." Answer 3: This mindset is particularly worrisome with the implementation of EHR systems, which often automatically code encounters without regard to medical necessity. It is very easy to document high levels of history and exams, particularly for established patients, which will result in level four and five services when the medical necessity may dictate only level two or three services.
