AAPC CDEO Exam Syllabus Topics and Weighting
| Topic Areas | Topic Details, Courses, Books | No. Of Questions |
|---|---|---|
| Purpose of CDI | - These questions will assess your knowledge of holistic, integrated, aggregate use of the medical record, your ability to explain the goal of physician-based clinical documentation improvement, and your understanding of improved patient outcomes as well as health and status. | 5 |
| Provider communication and compliance | - These questions will assess your ability to explain how the OIG can assist in determining areas of CDI focus. You will also need to demonstrate your ability to write a non-leading provider query, provide a rationale for queries, and be able to identify strategies for communicating crucial messages. | 10 |
| Clinical conditions |
- For each of the clinical conditions listed below, the exam will test your understanding of clinical picture, criteria for diagnosis (lab work, radiology, etc.), common medications, common abbreviations, and common treatment profiles, as well as your understanding of documentation requirements necessary for code assignment based on ICD-10-CM guidelines.
|
20 |
| Diagnosis coding | - This section will test your ability to identify clinically active versus historical conditions, ensure support documented for etiology and manifestation, apply coding clinic guidance to ICD-10 coding issues, recall ICD-10-CM outpatient coding guidelines, code selected conditions to the highest level of specificity that documentation supports, and select the first listed diagnosis on a claim. | 10 |
| Documentation requirements | - This section will address your ability to properly correct errors and audit requirements of who documented; identify cloned and cut and paste documentation and requirements for a complete medical record; understand requirements for proper use of templates; identify correctly authenticated notes in situations where multiple authors have documented within a note (MA, scribe, provider); demonstrate an understanding of the responsibilities of medical and clinical staff as it relates to documentation, electronic signature requirements versus paper signature requirements, documentation to support billing and coding for supplies (drugs) administered in office, and documentation to support diagnostic tests (labs, radiology, medicine); select the codes from a coding software pick lists; identify clinically valid diagnoses when considering number of conditions managed and treated and identifying "note bloat"; manage problem lists; distinguish between acceptable and unacceptable use of abbreviations within the medical record (legibility); and understand timely completion of medical records. | 10 |
| Payment models | - This area will test your understanding of fee-for-service payment methodology, new payment models, and documentation requirements (e.g., bundled payments, value-based payment modifiers); your ability to explain how the HCC risk adjustment model can determine areas of CDI focus; and how documentation affects HCC risk adjustment and patient RAF scores. | 5 |
| Procedure coding | - This section will test you on your ability to apply E/M guidelines to determine complexity of medical decision making, CPT® Assistant guidance related to procedure coding, CPT® coding guidelines, and your understanding of significant and separately identifiable when coding multiple E/M services and E/M services with procedures. You also will need to show how analysis of data applies to complexity of medical decision making (interpreted by a physician), that you can evaluate physician documentation to determine complexity of medical decision making, and identify correct use of time in documentation of E/M. Lastly, you will be tested on your knowledge of sick visits reported with preventative visits. | 10 |
| Quality measures | - This section will test your understanding of strategies for capturing quality measures within documentation, the requirements for meaningful use, and the purpose of the STARS rating and the domains. You also must be able to demonstrate knowledge of quality measures and other value-based payment systems, identify PQRS measures and proper documentation for support, and identify HEDIS measures. | 10 |
| Cases | - For this section, you will need to be able to identify documentation to support codes, identify documentation deficiencies in a medical record, select provider queries applicable to the medical record, select supporting regulations to identify why additional documentation is required, and select the correct codes based on documentation. | 10 cases, 20 questions |
