The Company is still assessing each LCD&#8217;s goniotomy coverage determinations and their potential impact on continued or discontinued coverage for its SION<sup style="font-size:75%; vertical-align:top">TM</sup> Surgical Instrument technology. </p> <p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">If the LCDs become effective in their current form, the procedures identified in the LCDs as investigational would be noncovered for Medicare beneficiaries in the states administered by these five MACs. The states served by these five MACs accounted for an aggregate of approximately 63% of the Company&#8217;s Surgical Glaucoma revenue in 2022.</p> <p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Company strongly disagrees with each LCD&#8217;s characterization of adult canaloplasty in combination with trabeculotomy ab interno, a procedural description associated with the OMNI technology, as investigational and is pursuing all remediation possibilities to maintain or reinstate coverage.&#160;The Company&#8217;s continuing efforts include concerted engagement with each MAC, the Centers for Medicare&#160;&amp; Medicaid Services, and clinical societies, as well as sharing clinical data supporting the long-term safety and efficacy of OMNI with these entities, to maintain or reinstate coverage for procedures performed with the OMNI technology.&#160;However, if the LCDs become effective in their current form, the Company intends to promptly initiate an LCD reconsideration request process with each MAC, in addition to taking such other measures as it may deem necessary or advisable. </p> <p style="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman;font-weight:bold">Cautionary Note Regarding Forward-Looking Statements </p> <p style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">This Current Report on Form <span style="white-space:nowrap">8-K</span> (this &#8220;Current Report&#8221;), together with other statements and information publicly disseminated by the Company, contains certain forward-looking statements within the meaning of Section&#160;27A of the Securities Act&#160;of&#160;1933, as amended and Section&#160;21E of the Securities Exchange Act&#160;of&#160;1934, as amended which statements are subject to considerable risks and uncertainties.
