CCDS Practice Test

The CCDS Practice Test is a free intermediate-level, 20-minute skill test from Science of Apps. It tests readiness for the ACDIS Certified Clinical Documentation Specialist (CCDS) exam — running a CDI programme and its metrics, compliant query practice, coding, MS-DRGs, severity and risk adjustment, and the clinical evidence behind commonly queried conditions such as sepsis, acute respiratory failure, acute kidney injury, malnutrition and heart failure — written to the AHIMA/ACDIS Guidelines for Achieving a Compliant Query Practice (2022), ICD-10-CM/PCS official guidelines, CMS payment rules and clinical guidelines from KDIGO, SCCM and ASPEN for 2026. Score 70% or more on its 20 questions to earn a verifiable CCDS Readiness certificate (SOA-CCDS). Every question is based on published standards and research — including Guidelines for Achieving a Compliant Query Practice (2022 update) (AHIMA and ACDIS), Clinical documentation integrity resources (ACDIS), ICD-10-CM classification and guidelines (CDC National Center for Health Statistics) — and each answer is explained with its source.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: Guidelines for Achieving a Compliant Query Practice (2022 update) (AHIMA and ACDIS); Clinical documentation integrity resources (ACDIS); ICD-10-CM classification and guidelines (CDC National Center for Health Statistics); What is medical billing? (AAPC); StatPearls (NCBI Bookshelf, National Library of Medicine); Project Play: youth sports resources (Aspen Institute). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: CDI Programme and Metrics (Programme goals, Review process and Metrics); Compliant Query Practice (Query formats, Leading queries and Escalation); Coding, DRGs and Risk Adjustment (MS-DRGs and CC/MCC, POA indicators and Severity and HCCs); Clinical Indicators for Common Queries (Sepsis and respiratory failure, Kidney and nutrition and Cardiac and neurological). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Clinical documentation integrity specialist, CDI nurse or physician advisor, Inpatient coder moving into CDI, HIM or revenue integrity analyst and CDI manager. It suits anyone who wants a quick, verifiable way to show CCDS knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

ACDIS requires experience in clinical documentation integrity plus a clinical or coding background, such as an RN, physician, or credentialed coder with clinical coursework. Check ACDIS for the current eligibility pathways and exam format.

A query that asks the provider to clarify documentation without leading them: it presents the clinical indicators from the record, offers clinically reasonable options including "other" and "clinically undetermined", and never mentions financial impact.

No. It is an independent practice test written to the publicly available CCDS content outline for 2026 and 2027, for checking your readiness before you book the real exam. Passing earns a Science of Apps certificate rather than the official credential.
