NORTH TEXAS (CBSDFW.COM) – A billing error led to personal information about some of a major nonprofit healthcare system’s patients to be sent to other patients in the mail.

Texas Health Resources said information was “matched with and sent to the incorrect guarantor,” which is often a health insurance policy’s primary holder.

About 82,000 patients were impacted, according to Texas Health spokesman Stephen O’Brien.

From patient’s names, account numbers, service dates, doctor’s name, amount owed and in some instances, a description of services rendered were sent.

However, patient social security numbers, health insurance identification numbers, or financial information were not disclosed in this incident, according to O’Brien.

The misconfiguration happened  between approximately July 19, 2019 through September 4, 2019.

Here are the Texas Health facilities affected by the incident:

  • Texas Health Presbyterian Hospital Allen
  • Texas Health Presbyterian Hospital Denton
  • Texas Health Presbyterian Hospital Dallas
  • Texas Health Arlington Memorial Hospital
  • Texas Health Harris Methodist Hospital Hurst Euless Bedford
  • Texas Health Harris Methodist Hospital Alliance
  • Texas Health Harris Methodist Hospital Fort Worth
  • Texas Health Harris Methodist Hospital Southwest Fort Worth
  • Texas Health Harris Methodist Hospital Cleburne
  • Texas Health Harris Methodist Hospital Azle
  • Texas Health Harris Methodist Hospital Stephenville
  • Texas Health Harris Methodist Hospital Kaufman
  • Texas Health Specialty Hospital Fort Worth
  • Texas Health Presbyterian Hospital Plano

There were also four Texas Health joint ventures affected: Texas Health Presbyterian Hospital Rockwall, Texas Health Center for Diagnostics and Surgery Plano, Texas Health Heart and Vascular Hospital Arlington and Texas Health Harris Methodist Hospital Southlake.

Texas Health said it has no indication that any information has been misused. However, in an abundance of caution, it mailed notification letters to patients whose information may have been affected by this incident.

They also established a dedicated call center to answer any question patients may have. If you do not receive a letter by November 15, 2019 and believe you may be affected, or for additional information about this situation, you may call 1-844-996-1030, Monday through Friday, 8 a.m. to 5:30 p.m. Central Time.
