What is clinical documentation integrity (CDI)?
Clinical documentation integrity (CDI) is the practice of ensuring provider documentation is complete, precise, and valid — so the medical record accurately supports the codes assigned to it (ICD-10, CPT, HCPCS). CDI specialists review records and query providers to clarify or clinically validate the documentation behind a diagnosis or service. CDI bridges the gap between clinical care and accurate coding.
CDI in plain terms
Coding can only be as good as the documentation it rests on. CDI exists to make sure the record actually says what happened — clearly and specifically enough that the right codes can be assigned and defended. The discipline used to be called clinical documentation improvement; the current term, integrity, emphasizes accuracy and validity over simply capturing more.
What CDI specialists do
CDI professionals are, in AHIMA's framing, the translators and validators of the health record. Their core loop is record review plus the provider query: they read the documentation, spot gaps or ambiguities, and ask the provider to clarify or confirm — following compliant query practices so the question never leads the provider toward a particular answer.
CDI vs coding
| CDI | Coding | |
|---|---|---|
| Job | Ensure the documentation is complete & valid | Assign the standardized codes from it |
| Tool | Record review + provider query | Code assignment per guidelines |
| Relationship | Improves the input | Depends on the input |
Who sets the standards
Two organizations anchor the field: the American Health Information Management Association (AHIMA) and the Association of Clinical Documentation Integrity Specialists (ACDIS), which joined the AHIMA Enterprise in 2023. Together they publish guidance such as the practice brief on compliant query practice, and they credential the field — ACDIS's CCDS (and CCDS-O) and AHIMA's CDIP.
How Capsa relates to CDI today
CDI is fundamentally about clinician-governed accuracy — and that's already how Capsa Charge Capture works. The clinical logic lives in explicit, human-readable rules, and CDI nurses — not engineers — own and approve those rules through a guided workflow, answering clarifying questions and signing off on changes with a complete audit trail. A dedicated Capsa CDI product, which would flag documentation gaps before the claim goes out, is on the suite roadmap.
