Litton and Giddings Radiological Associates (LGRA) in Springfield, Mo., has issued a warning to its patients to monitor their personal accounts after a possible breach of billing information.

In a statement to the media, the group practice said that on July 31 and August 2 the janitorial services provider at its billing company mistakenly sent patients’ paper billing records to a local recycling center without first shredding the documents.

LGRA said it learned of the error on August 10, and that the billing company has made assurances that its vendors are aware of the procedures for destruction of patient records. There is no indication that any patient information has been misused, but patients are being notified “out of an abundance of caution,” said Jay Smith, business manager for LGRA.

All LGRA patients who had any billing activity between July 23 and August 2 have been mailed letters of notification, though the exact patient information or documents that were sent to the recycling facility unshredded could not be identified.

Patients were urged to monitor account statements, letters from insurers and credit reports, and contact 877-615-3742 if they have questions, according to LGRA.
