Data validation in health information management is the process of ensuring data meet predefined rules and quality standards. This involves checks for completeness, correct formats, and valid codes, along with logical cross-field checks to catch inconsistencies. For example, validating the date of birth against the stated age can reveal impossible or mistaken entries, and confirming that ICD-10 codes entered are valid helps ensure accurate diagnosis coding. Data validation is essential for accurate patient care, proper billing, and reliable reporting, and it’s a standard, not optional, practice used across clinical and administrative data—not just for research and not simply as a backup process. When data don’t meet the rules, the system flags the issue so it can be corrected before the record is used.
