ACDIS CCDS-O study guide
ACDIS CCDS-O · Work through your exam, one topic at a time.
The Certified Clinical Documentation Specialist-Outpatient (CCDS-O) is a credential offered by ACDIS for clinical documentation integrity (CDI) professionals who work outside the inpatient setting. Per ACDIS, it "provides a trusted baseline of competency for CDI in the outpatient setting, which includes physician practices, hospital clinics, and the emergency department, among other settings," and it "represents a mark of excellence for CDI professionals operating in outpatient settings, and provides employers with a baseline of competency for existing staff or potential hires." That employer-facing purpose explains who typically pursues it: outpatient CDI specialists and reviewers, coding and revenue cycle staff moving into documentation work, practice and clinic managers who oversee documentation quality, and clinicians or educators who support outpatient query practice. The ACDIS CCDS-O study guide has 4 sections and about 1,470 words.
01Outpatient CDI in Physician Practices
Outpatient CDI in physician practices focuses on the ambulatory record as the source for professional E/M levels, diagnosis coding, risk adjustment, and quality reporting. The exam tests whether you can spot undocumented specificity, support HCCs with MEAT, apply the 2021 office/outpatient E/M rules, and query without leading the provider.

Hospital clinics-provider-based outpatient departments and hospital-owned ambulatory clinics-add a facility/professional split to outpatient CDI.

Emergency department CDI covers professional and facility documentation in the ED, where rapid, episodic care creates high coding risk.
