This document provides coding and billing guidelines for Emergency Department Providers (facilities and physicians or other qualified health care professionals (QHPs)) to ensure the code(s) billed meet the coding requirements.
Emergency Department (ED) Evaluation and Management (E&M) codes are typically reported per day and do not differentiate between new or established patients. There are 5 levels of ED services represented by CPT codes 99281 – 99285. The ED codes require all three key components (history, examination and medical decision-making) to be met and documented for the level of service selected.

The level of service billed must be based on the intervention(s) that are performed in relationship to the medical care required by the presenting symptoms and resulting in diagnosis of the patient. Professional codes are based on complexity, performed work; which includes the “cognitive” effort. Facility codes reflects volume and intensity of resources used by the facility to provide care.
Medical records and documentation may be requested from the provider to support the level of care rendered. The documentation must clearly identify, and support ED E&M codes billed. If a denial is appealed, the supporting documentation must be included in the appeal request.
The tables below provide criteria that Blue Cross Blue Shield of North Dakota (BCBSND) will use to determine the appropriate code application for ED services.
