Certified Documentation Expert Outpatient (CDEO)® certification
The Certified Documentation Expert Outpatient (CDEO) credential validates expertise in reviewing outpatient documentation for accuracy to support coding, quality measures, and clinical requirements. CDEO professionals give feedback to providers to improve clinical documentation and facilitate ongoing documentation improvement to meet all requirements of the medical record.
To become a CDEO, documentation professionals must demonstrate knowledge of pathophysiology, coding and billing guidelines, and quality measures.

Equipment required for exam
Our live remote proctored exam requires a closed room free from distraction with window coverings, a reliable, high-speed internet connection, a computer, and an external webcam that can be positioned to show your face, hands, keyboard, and the area around the keyboard (about 10 inches).
Exams taken at a testing center do not require any special equipment from the test-taker.
Experience requirements
Must be able to demonstrate an understanding of the proper application of CPT®, ICD-10-CM, and HCPCS Level II codes, and quality measures. Examinees must also demonstrate knowledge of proper query procedures and effective communication for documentation improvement.
Clinical documentation improvement involves compliance to documentation requirements and effective communication with providers to improve documentation. CDEO candidates should undergo certification training and/or have experience in clinical documentation improvement.
Please be aware that this is a difficult, high-level examination and not intended for individuals with limited clinical documentation improvement background.
