About Interim HealthCare of Oklahoma City, Inc.
Interim HealthCare of Oklahoma City, Inc. is a Medicare-certified home health agency and homecare provider based at 3613 NW 56th Street in Oklahoma City, Oklahoma. Founded in 1999, it is a locally owned, veteran- and RN-owned franchise of the national Interim HealthCare brand and offers skilled nursing, hospice, palliative care, personal care support, behavioral health, veteran and spouse care, and neonatal and pediatric home care. Because the organization provides healthcare services to patients in their homes, it routinely handles sensitive personal and medical information, making data security incidents particularly significant for the people it serves.
What Happened?
Interim HealthCare of Oklahoma City, Inc. was listed in an HHS Office for Civil Rights breach portal report submitted on July 31st, 2026. The filing describes a hacking and IT incident affecting email and network server systems, with 500 individuals reported as affected. No business associate was identified as involved. The specific types of data exposed were not specified in the HHS filing. It is worth noting that under HIPAA reporting rules, entities sometimes submit an initial filing using 500 as a placeholder figure while a full investigation is ongoing, so the actual number of people affected may be higher.
Separately, dark web monitoring sources and reporting from DataBreaches.net indicate that the ransomware group known as Genesis claimed responsibility on approximately August 10th, 2026, for an attack on Interim HealthCare entities in Oklahoma City and Tulsa. The Genesis group alleged possession of more than 1 TB of data, including what it described as patient records and internal documents — these are unverified attacker claims and have not been confirmed by Interim HealthCare of Oklahoma City or any regulator. As of August 29th, 2026, DataBreaches.net reported that no breach notice had appeared on the company’s website and that the organization had not publicly addressed the Genesis claim. A separate ransomware group called Anubis also claimed an attack around August 15th through 21st, 2026, but that claim targets the national Interim HealthCare corporate headquarters in Sunrise, Florida — a distinct entity from the Oklahoma City franchise. Two law firms, Migliaccio & Rathod LLP and Zimmerman Law Offices, announced investigations into this incident as of August 12th, 2026. No class action lawsuit against the Oklahoma City entity has been filed as of available reporting.

What Should You Do?
If you believe your information was involved in this incident, take steps now to protect yourself. Enroll in any identity theft protection services offered by Interim HealthCare of Oklahoma City if and when they are announced. Place a fraud alert or credit freeze with the three major credit bureaus — Equifax, Experian, and TransUnion — to make it harder for anyone to open new accounts in your name. Monitor your existing financial accounts and request your free credit reports at AnnualCreditReport.com. If you suspect your identity has already been misused, report it and get a personalized recovery plan at IdentityTheft.gov. Because this incident involves a healthcare provider, carefully review any Explanation of Benefits statements from your insurer and check your medical records for services you did not receive, which can be a sign of medical identity theft.
