Advanced Medical Management, LLC (“AMM”), furnishing notice as a management service organization on behalf of MS- HC, LLC, and Excelsia PA, PLLC, would like to inform you of a recent incident that may have involved your Protected Health Information (“PHI”). We are providing notice under 45 CFR § 164.404.

WHAT HAPPENED? On May 11, 2023, AMM became aware of unauthorized activity to certain systems within its network. These systems were developed and maintained by third party vendors. We are not aware of any prior unauthorized activity over the many years these systems have been in use. Upon discovery, AMM promptly launched a comprehensive investigation with the assistance of third-party cybersecurity experts and took steps to ensure its systems are secure. AMM also notified law enforcement. With the assistance of its cybersecurity experts, AMM determined that an unauthorized party gained access to certain databases containing PHI between May 10, 2023, and May 13, 2023. AMM then began an extensive review of its records to properly identify the individuals impacted by the event and the associated data for the affected individuals. This review concluded on June 22, 2023. You are receiving this letter because AMM determined that certain information related to you may have been subject to unauthorized access and disclosure by the unauthorized party.

WHAT INFORMATION WAS INVOLVED? The following types of your PHI may have been involved: name, address, email, phone number, date of birth, social security number, driver’s license, treatment or diagnosis information, provider name, dates of service, account number, guarantor ID, policy number, health insurance information, health insurance policy number, or treatment cost information. At this time, we have no evidence to suggest your PHI has been misused.

WHAT WE ARE DOING. AMM is committed to, and takes very seriously, its responsibility to protect all data entrusted to us. As part of our ongoing commitment to the privacy of PHI in our care, we reviewed our existing policies and procedures, and have implemented additional safeguards to further secure the information contained within our network. AMM is also notifying regulators, as required by law. As an expression of our commitment to you, we are offering access to complimentary credit monitoring services through Experian Identity Works, as detailed below.

WHAT YOU CAN DO. You can review the enclosed Additional Steps to Protect Your Personal Information. You can also enroll to receive the complimentary credit monitoring services being offered to you. It is always a good practice to remain vigilant for suspicious activity and to regularly review your financial statements and credit reports. You should also be on guard for schemes, known as phishing attacks, where malicious actors may pretend to represent AMM or reference this incident.

When you receive your credit reports, review them carefully. Look for accounts or creditor inquiries that you did not initiate or do not recognize. Look for information, such as home address and Social Security number that is not accurate. If you see anything you do not understand, call the credit reporting agency at the telephone number on the report.

Place a Credit Freeze

You have the right to put a security freeze, also known as a credit freeze, on your credit file, so that no new credit can be opened in your name without the use of a Personal Identification Number (PIN) that is issued to you when you initiate a freeze. A credit freeze is designed to prevent potential credit grantors from accessing your credit report without your consent. If you place a credit freeze, potential creditors and other third parties will not be able to access your credit report unless you temporarily lift the freeze. Therefore, using a credit freeze may delay your ability to obtain credit. Pursuant to federal law, you cannot be charged to place or lift a credit freeze on your credit report. Should you wish to place a credit freeze, please contact all three major consumer reporting agencies listed below.

P.O. Box 105788

1) Full name, with middle initial and any suffixes;
2) Social Security number;
3) Date of birth (month, day, and year);
4) Current address and previous addresses for the past five (5) years;
5) Proof of current address, such as a current utility bill or telephone bill;
6) Other personal information as required by the applicable credit reporting agency;

If you request a credit freeze online or by phone, then the credit reporting agencies have one (1) business day after receiving your request to place a credit freeze on your credit file report. If you request a lift of the credit freeze online or by phone, then the credit reporting agency must lift the freeze within one (1) hour. If you request a credit freeze or lift of a credit freeze by mail, then the credit agency must place or lift the credit freeze no later than three (3) business days after getting your request.

Place a Fraud Alert

You also have the right to place an initial or extended fraud alert on your file at no cost. An initial fraud alert lasts 1-year and is placed on a consumer’s credit file. Upon seeing a fraud alert display on a consumer’s credit file, a business is required to take steps to verify the consumer’s identity before extending new credit. If you are a victim of identity theft, you are entitled to an extended fraud alert, which is a fraud alert lasting 7 years. Should you wish to place a fraud alert, please contact any one of the agencies listed below. The agency you contact will then contact the other two credit agencies.
