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.

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.
