Did you receive a letter from Northwest Medical Specialties about a cyber-attack? Thousands of patients just learned that highly sensitive medical and financial details were stolen from the provider’s network. Act now — discover what was taken, how to protect yourself, and whether you can pursue compensation.
What Happened?
On August 18, 2025, Northwest Medical Specialties PLLC (NWMS) — a Washington-based oncology and hematology practice — learned that an unauthorized actor had infiltrated its computer network. A forensic investigation revealed that the intruder copied certain files on August 15, 2025, placing thousands of patients at risk of identity theft.
How Many Patients Were Affected?
NWMS reported the incident to the Washington State Attorney General on August 28, 2025, stating that exactly 3,846 Washington residents were impacted. Written notice letters began mailing on September 3, 2025.
What Information Was Exposed?
The compromised files may have contained both personally identifiable information (PII) and protected health information (PHI), including:
- Full names & contact details
- Dates of birth
- Social Security numbers
- Government-issued ID numbers
- Addresses
- Health insurance information
- Medical records
- Payment card or other financial details
With these data points, criminals can open new lines of credit, submit fraudulent insurance claims, or stage convincing phishing attacks.
Northwest Medical Specialties’ Response
In addition to federal and state reporting requirements, NWMS is offering 12 months of TransUnion Cyberscout single-bureau credit monitoring and identity-protection services at no cost to those affected.
Recommended Steps to Protect Yourself
- Enroll in free credit monitoring. Follow the unique sign-up code provided in your notice letter.
- Review credit reports. You are entitled to one free report annually from each bureau. Look for unfamiliar accounts.
- Set fraud alerts or a credit freeze. This makes it harder for scammers to open new credit in your name.
- Watch medical and insurance statements. Question any unfamiliar services or providers.
- Stay alert for phishing. Do not click suspicious links or provide information by phone or email.
- Document out-of-pocket expenses. Keep receipts for postage, credit-freeze fees, or professional services — these may be recoverable.
Do You Have a Legal Claim?
Healthcare providers are legally required to safeguard PHI under HIPAA and state privacy laws. When they fail, victims may pursue compensation for:
- Reimbursement of fraud-related losses and credit-monitoring costs
- Compensation for time spent addressing the breach
- Payment for emotional distress and loss of privacy
- Punitive damages where allowed
