What Is Clinical Documentation Improvement?
Clinical documentation improvement, commonly abbreviated CDI, refers to the process of reviewing clinical documentation during and after a patient's hospital stay to ensure it accurately and completely reflects the patient's severity of illness, complexity, and services provided. CDI programs bridge the gap between clinical care and the coded data used for reimbursement and quality reporting.
Purpose of CDI Programs
CDI programs aim to improve the accuracy, specificity, and completeness of provider documentation. Accurate documentation supports appropriate DRG assignment, accurate risk adjustment, quality measure reporting, and reduced compliance risk from either overcoding or undercoding.
The CDI Review Process
CDI specialists, often registered nurses or credentialed HIM professionals, review patient records concurrently during the hospital stay to identify gaps, ambiguities, or missing specificity in documentation. Reviews focus on identifying conditions that are clinically evident from test results or treatment but not explicitly documented by the provider.
The Physician Query Process
When documentation is unclear, conflicting, or incomplete, CDI specialists issue a formal query to the treating provider requesting clarification. Compliant queries must be non-leading, clinically supported by evidence in the record, and must never suggest a specific diagnosis simply to increase reimbursement. Queries may be verbal or written, and organizations should maintain query templates that comply with AHIMA and ACDIS query practice guidance.
Physician Engagement Strategies
- Providing regular, specialty-specific documentation education
- Sharing individualized physician documentation and query response metrics
- Securing physician champions to promote CDI initiatives among peers
- Integrating documentation prompts into the electronic health record workflow
Key CDI Program Metrics
- Query response rate and query agreement rate
- Case mix index changes attributable to documentation improvement
- CC and MCC capture rate
- Physician query volume by provider and specialty
Impact on Data Quality
Effective CDI programs improve the accuracy of coded data used throughout the organization, including quality reporting, risk adjustment, and internal severity-adjusted mortality and complication tracking. Without strong documentation, even excellent clinical care can appear less severe or complex than it truly was, skewing quality metrics and reimbursement.
The HIM Role in CDI
HIM professionals often lead or collaborate closely with CDI teams, ensuring queries comply with coding guidelines and ethical standards, and reconciling any discrepancies between CDI specialist and coder DRG assignments prior to final billing.
Conclusion
Clinical documentation improvement programs are essential for ensuring that the coded record accurately reflects patient severity and care complexity, supporting accurate reimbursement and reliable quality data.
