Is it possible to identify an admission or discharge through TEDS?

No. An important feature of TEDS reporting is its use of non-protected health information (non-PHI). No personally identifiable information, or PII, as defined under the Health Insurance Portability and Accountability Act (HIPAA) rule for PHI, is reported in the data files. The data files use a unique, non-PHI ID for reporting the required and optional information.
