PARIS -- (Marketwire) -- 01/07/13 -- Mauna Kea Technologies (NYSE Euronext: MKEA), leader in the optical biopsy market and developer of Cellvizio®, the fastest way to see cancer, announced today that Cellvizio procedures in the upper GI tract have been added to the Ambulatory Surgical Center (ASC) approved procedure list. Ambulatory Surgical Centers are health care facilities focused on providing same-day surgical care, including diagnostic and preventative services, often times found to be more convenient than hospital-based outpatient procedures. The U.S. Centers for Medicare and Medicaid Services (CMS) has approved the payment rate of $520 per previously-awarded Category 1 Current Procedural Terminology (CPT®) codes for the use of Cellvizio® during endoscopy procedures in the upper gastrointestinal tract.

GI related procedures make up 24% of all specialties served at ambulatory surgical centers(i). There are approximately 5,000 ambulatory surgical centers(ii) across the United States, each one performing more than 3,700(iii) GI endoscopy procedures each year, representing a total of about 18 million GI procedures.

Cellvizio is used at hospitals throughout the United States and the rest of the world to provide physicians live-cellular level views of the GI tract to help identify and rule out cancer and guide treatment decisions in real-time.

"We're pleased with the addition of Cellvizio optical biopsies to the list of approved procedures performed in ambulatory surgical centers across the country and believe this opens a much larger market segment for Cellvizio in the United States, our largest clinical market," said Sacha Loiseau, PhD, Founder and CEO of Mauna Kea Technologies. "This is a major milestone in our efforts to make optical biopsies available to a majority of patients with suspected GI diseases, in order to grant them access to a streamlined diagnostic work-up and to a faster treatment decision."

The Category I CPT codes issued by the American Medical Association (AMA) include 43206 for the Cellvizio esophageal optical endomicroscopy and 43252 for esogastroduodenoscopy with optical endomicroscopy. The CPT codes went into effect on January 1, 2013.
