Novitas Solutions, Opko Health's Medicare Administrative Contractor, has followed through on its initial non-coverage determination for 4Kscore issued in May 2018 and has communicated its intention to stop reimbursing for the test as of March 20, 2019, Barrington analyst Michael Petusky tells investors in a research note. Opko has spent the past eight months trying to communicate the value of 4Kscore to Novitas "and has clearly fallen short in this effort," says Petusky. The analyst, who "highly" doubts this decision will be reversed "any time soon," believes in the value of the test based on experts he's heard weigh in on the issue. The news is very disappointing, but Opko will continue to have some near-term opportunity to continue to educate commercial payors and perhaps get some "wins," Petusky writes. He reduced his annual revenue estimate for 4Kscore contribution by about $15M and keeps an Outperform rating on Opko Health with a $7 price target.
