Investigation notes

Grafton City Hospital Inc, located in Indiana, officially reported a data security incident to state regulators on August 21, 2026.

The hospital's notification indicates that the compromised information includes Full Name, Date of Birth, Social Security Number, Medical Record Number, Health Insurance ID Number, Diagnosis and Treatment Information, Prescription Information, Provider and Treatment Dates, and Home Address.

As a healthcare provider, Grafton City Hospital Inc is obligated under federal law, specifically HIPAA, to implement robust safeguards for patient data.
