E/M Coding Clinic: Correctly Reporting 99283 vs. 99284 Means Understanding the History and Physical- Published on Fri, Oct 01, 1999
Latest on Accurate Use of CPT Codes 99283 and 99284 from SuperCoder's E/D Coder: Definition: An emergency service (ED) is performed in the emergency department. CPT code range 99281-99285 are applied for either a new or returning patient. Services that are performed outside of the emergency department (in an office or outpatient setting) cannot be billed with ED codes because they are reserved for hospital-based facilities that are open 24 hours a day. To choose which level is appropriate, at least three or more required key components (History, Exam and Medical Decision-Making) must be documented.

requires a detailed history and physical.
However many coding and billing experts are warning that just because the physician documents a more extensive history and physical than is required for a 99283 the service provided does not merit reporting 99284.
I have done chart audits on Level 3 and Level 4 visits because the medical decision-making is the same and I have seen some that I didnt think used very good judgment says Jackie Davis president of Term Billing an emergency medicine billing company in Austin TX. For example I saw a lot of otitis media (infection of the middle ear) coded at a Level 4. No matter what the guidelines are you still have to use common sense and integrity. Treatment of otitis media is rarely going to warrant a Level 4 maybe with a complication such as bronchitisbut almost never just otitis media by itself.
Requirements of History
