The primary purpose of clinical documentation improvement (CDI) is to:

In outpatient CDI, the foundational aim is documentation integrity—making sure the medical record clearly and consistently tells the clinical story: why the patient is being seen, what conditions are evaluated/managed, the current severity and associated risks, what was done (assessment and treatment), and how this supports medical necessity and accurate code assignment. While reimbursement can be affected, it is an outcome—not the purpose. ACDIS-aligned CDI education emphasizes completeness and specificity so the record reflects true acuity and complexity (e.g., chronic conditions with current status, complicating comorbidities, medication management, and risk/decision-making). This improves downstream quality reporting, risk adjustment accuracy, continuity of care, and compliance because coders must code what is documented, not what is presumed. Strong CDI reduces denials and audit exposure by ensuring diagnoses are clinically supported (MEAT—monitor, evaluate, assess/address, treat) and linked to the encounter’s work. In short, CDI exists to ensure the record accurately represents the patient’s condition and the care delivered, enabling correct coding, quality measurement, and appropriate payment.
