ROUND ROCK, Texas and SAN DIEGO, Feb. 11 /PRNewswire/ -- MyDocOnline(TM), a subsidiary of Aventis, today released MyDocOnline(TM) Dr. Chart(R) version 8.0, an electronic lab communication tool that links laboratories to healthcare providers via the Internet to automate the manual activities associated with lab orders and result reporting. MyDocOnline Dr. Chart will be demonstrated at The Healthcare Information and Management Systems Society (HIMSS) annual conference in San Diego, February 9-13, 2003.

MyDocOnline provides innovative tools that enable online communication across the healthcare community, enhancing efficiency and patient care. MyDocOnline Dr. Chart, part of the clinical suite offered by MyDocOnline, enables healthcare providers to initiate lab orders online, automate approval processes for lab reimbursement known as medical necessity compliance, and facilitate viewing of results rapidly and accurately. The functionality can also help reduce costly reimbursement denials by providing automatic Medicare compliance and Advanced Beneficiary Notices (ABNs) responsible for informing a patient when coverage cannot be applied, and requiring the patient's authorization to ensure lab costs are personally covered.

"The Dr. Chart offering demonstrates our ability to provide efficiencies across the entire healthcare community," said Kirk Schueler, CEO of MyDocOnline. "Our strength and comprehensive offerings in the marketplace provides us with the opportunity to extend MyDocOnline's communication tool as a channel between healthcare providers, their clinical and administrative partners, and their patients."

The features of MyDocOnline Dr. Chart are easy-to-use by physicians and their staff. The Dr. Chart tool comes with customizable easy-to-read screens, built-in alerts and messaging, and automatic printing of bar-coded labels. Most importantly, MyDocOnline Dr. Chart provides secure Internet connections and encryption of data to help ensure patient privacy is protected.

MyDocOnline Dr. Chart is introducing additional features in Dr. Chart version 8.0. MyDocOnline Dr. Chart can be purchased as a standalone product or in combination with other products in the MyDocOnline suite, such as MyDocOnline(TM) Connect. The product will be demonstrated at booth number 1547 at the HIMSS conference.
