What happened

CardioFit Medical Group is a solo cardiology practice in Torrance, California, led by Dr. Leonard J. Scuderi, M.D., F.A.C.C. The practice focuses on interventional and preventive cardiology, venous therapy, and longevity medicine.

On five separate dates in January and February 2026 (January 8, January 9, January 18, January 22, and February 5), CardioFit transmitted patient information via email without encryption. The practice discovered the unencrypted-transmission incidents on February 17, 2026.

CardioFit filed a sample notification letter with the California Attorney General on April 9, 2026 under California’s new SB 446 timeline (effective January 1, 2026), and mailed individual notification letters on April 10, 2026 confirming 7,243 affected individuals.

This is not a ransomware or external-attacker event — it is an internal procedural failure (unencrypted email transmission). HHS OCR classifies it as Hacking/IT Incident at Email at the taxonomy level, but no external actor is involved.

What CardioFit is offering

CardioFit’s notification letter does not offer complimentary credit monitoring or identity theft protection. The letter instructs recipients to obtain free fraud alerts from Equifax, Experian, and TransUnion on their own.

Toll-free inquiry line: (888) 341-2513

The absence of credit monitoring is unusual for a healthcare breach affecting 7,243 individuals, though the no-SSN exposure profile partially mitigates the typical identity-theft risk.

What to do

Read your specific notification letter to confirm what data elements were involved in your case.
Place free fraud alerts at the three credit bureaus as a baseline precaution.
Watch your insurance Explanation of Benefits statements for unfamiliar cardiology or specialty claims.
Stop the ongoing flow of your cardiology data. HealthConsent files HIPAA restriction requests so the diagnostic and treatment data exposed in this breach is not continuously re-shared.

Stop your data from spreading further

Credit monitoring covers your wallet. HealthConsent covers your health records.

Your stolen diagnoses, test results, and medical record numbers don’t expire when the free credit-monitoring window ends.
