Certified Outpatient Documentation Expert Training

Certified Outpatient Documentation Expert (CDEO)

The Certified Documentation Expert Outpatient (CDEO) Certificate of Authorization confirms specialist knowledge in verifying the accuracy of outpatient documentation to support coding, quality measurements, and clinical requirements. CDEO experts provide feedback to providers to improve clinical documentation and enable continuous improvement of documentation to meet all medical record requirements. To become CDEO, documentation professionals must demonstrate knowledge of pathophysiology, coding and billing guidelines, and quality metrics.

The CDEO exam

  • 150 multiple choice questions (supervised)
  • 5 hours and 40 minutes to complete the exam
  • A free rehearsal
  • Open codebook (manuals)
  • The exam consists of questions to review outpatient medical records to verify the accuracy and correct application of CPT®, ICD-10-CM, HCPCS Level II codes and quality measures. Applicants should also demonstrate knowledge of proper interview procedures and effective communication to improve documentation.
