AAPC Emergency Department (CEDC) Examination Practice Test
Emergency department coding requires translating a fast-moving visit into accurate, well-supported professional service reporting. CEDC practice material focuses on documentation details that affect emergency care records, including evaluation and treatment, procedures, medication services, diagnostic testing, and decisions such as discharge or critical care.
Exam overview
About the AAPC Emergency Department (CEDC) Examination Exam
Questions in this practice bank address how the medical record supports the services performed and the clinical decisions made during an emergency visit. Relevant skills include distinguishing a separately identifiable diagnostic service from other care, identifying documentation that supports a procedure or medication administration, and recognizing the time and record details needed for accurate reporting. Scenarios also involve critical care support, laceration repair, bedside ultrasound, and emergency department encounters that cross midnight. Documentation integrity is another practical concern: corrections to completed electronic records should preserve the original entry and show the change appropriately. The material also highlights clinically useful descriptions of response to treatment, discharge decisions, and medication instructions, including safe opioid management. These skills connect code selection to the actual work documented rather than relying on vague statements or assumptions.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A physician is considering whether a patient with a head injury can be discharged. Which factor is most important to document when it materially affects that decision?
Show answer
Correct answer: ARelevant neurologic findings and their course help explain the clinical assessment and disposition decision for a head injury. Unrelated operational details do not substitute for clinically pertinent findings.
A physician performs a bedside ultrasound examination in the emergency department. Which documentation element is especially important to support reporting a separately identifiable ultrasound service?
Show answer
Correct answer: BWhen reporting a separately identifiable diagnostic ultrasound service, the record should support the study performed and its clinical use. The specific documentation requirements depend on the code and applicable payer or facility policy.
An emergency physician documents critical care for a seriously ill patient. Which general principle is important when supporting critical care reporting?
Show answer
Correct answer: BCritical care reporting generally requires documentation of qualifying, medically necessary critical care services and applicable time. Total time is not simply the patient’s time in the department, and separately reportable procedure time may need to be excluded under applicable rules.
A patient receives an injection of medication in the emergency department. Which documentation best supports reporting the administration service when applicable?
Show answer
Correct answer: AThe record should identify what medication was administered and how it was given, including relevant dose and route information. A discussion or prescription alone does not establish that a medication administration occurred.
A patient arrives at an emergency department at 11:50 p.m. and is discharged shortly after midnight. Which general principle should guide determination of the date of service for the emergency department professional service?
Show answer
Correct answer: CDate-of-service reporting should follow applicable coding and payer rules and be supported by the documented encounter. Crossing midnight does not, by itself, require splitting one continuous emergency department professional encounter.
A clinician needs to correct an error in a completed electronic medical record. Which approach best preserves record integrity?
Show answer
Correct answer: ACorrections should follow the organization’s approved process and preserve the history of the record, including the original entry and audit trail. Users should not conceal changes or enter corrections under another person’s credentials.
A patient is discharged with a new prescription. Which documentation best supports safe and understandable medication instructions?
Show answer
Correct answer: AThe record should reflect the instructions and precautions communicated, as relevant to the medication and encounter. A prescription alone does not establish what counseling was provided or whether key guidance was addressed.
How to use this practice test
The free CEDC practice set draws up to 20 random questions from a bank of 50. Use a session to test how well you apply documentation and reporting principles to emergency department scenarios, then review the results shown after the session to identify concepts that need more attention.
Preparation tips
- For procedure scenarios, identify the specific service performed and the record details that distinguish it from evaluation and management or other services.
- Practice checking whether documentation supports critical care, separately identifiable ultrasound, medication administration, and laceration repair before considering reporting.
- Work through encounters that cross midnight by separating the professional service date question from assumptions based only on discharge time.
- Review sound electronic record correction practices, including preserving the original documentation and making changes traceable.
- When assessing discharge or medication scenarios, look for documented clinical factors, response to treatment, and clear instructions that support safe follow-up.
