Thank you, Dennis. As many of you are aware, in early February, CMS issued an advance notice with proposed payment updates for Medicare Advantage programs for 2024, which included some potential changes to treatment of vascular disease under the Medicare Advantage risk adjustment model, creating uncertainty whether all identified patients with PAD will continue to qualify for an increased capitated payment. We have submitted comments on the proposed update to CMS for consideration, citing published research that shows the benefit of early diagnosis and treatment of PAD. It is premature to speculate about the impact to our customers and ultimately our business as CMS will issue the final 2024 rate announcement no later than April 3, 2023. Regardless of potential changes in reimbursement rates, we believe that QuantaFlo provides important clinical value to our customers in terms of better patient care and potential for future cost savings and identifying positive PAD patients and those with HD. We believe that earlier diagnosis will lead to earlier initiation of preventative intervention and treatment which will save lives and consequently lower health care expenditures. Now turning to guidance for the first quarter ended March 31, 2023. We expect revenue will range from $17.4 million to $17.8 million and pretax net income, which includes interest income of approximately $400,000, to range from $5.6 million to $5.8 million. We are on track to achieve our highest quarterly revenue ever, which we believe is a testament to the clinical value our customers see in using QuantaFlo to aid in the early diagnosis of PAD in their patient population. In light of the CEO transition and the anticipated final CMS rate announcement, we are not issuing guidance for the year ended December 31, 2023, at this time. Let's move on to the clinical study that was published in late February 2023 in the Journal of Preventative Medicine. Using QuantaFlo is an aid to assess heart dysfunction or HD. You can find a press release with a link to this study in the Investor Relations portion of our website. Health care providers now have a point of care low-cost, accurate means for detecting potential heart dysfunction in their primary care setting before overt signs of symptoms present. Results were that our tests showed a statistically significant correlation with a p-value of less than 0.01 with trans sporadic [ph] echocardiography, which is the gold standard to diagnose heart failure. For those of you who have been with Semler for a long time, you may recall the prolonged lead times for many of our current customers with the initial adoption of QuantaFlo for PAD. We expect the market uptake process for HD will take time. Other key points regarding this expansion are QuantaFlo HD can be used as an aid to measure chemodynamics related to heart dysfunction. The spectrum of heart dysfunction includes heart failure. Heart failure affects around 6.5 million adults in the U.S. And the lifetime risk of heart failure is estimated to be 1 in 5 at 40 years of age. The number of patients with asymptomatic heart disease exceeds the number of patients with symptomatic heart disease. Published studies have shown there are over 1 million hospitalizations per year in the United States from heart failure, and the annual cost of care exceeds $30 billion. Mortality rates after hospitalization for heart failure are 31% within 1 year after diagnosis. QuantaFlo HD uses the existing FDA 510k clearance as we anticipated its use many years ago. A medical assistant performs the test in a primary care setting, similar to how one uses QuantaFlo for PAD. Like PAD, asymptomatic HD patients are not routinely tested in the current standard of care because echo is not a screening test. This test is performed by referral in a specialized lab, requires a trained ultra-sonographer to perform the task, it’s about an hour and must be interpreted by a cardiologist. As a specialized procedure, echo is not practical to be performed in primary care offices or in home settings. The sensitivity, specificity and accuracy of QuantaFlo HD all were greater than 88% compared to using echo with strain as a gold standard as the methodology for identifying heart failure. Patients that have been identified as positive with QuantaFlo HD will need to have additional diagnostic tests to determine the underlying type of heart dysfunction. The goal is for health care providers to have a better chance of encouraging patients to adopt healthier lifestyles and optimize proven guideline-directed medical therapies earlier with the potential of improving long-term health outcomes. Currently, there are CPT reimbursement for echocardiography and HCC diagnostic codes for heart dysfunction. Moving on to our R&D goals. We continue to be -- to upgrade the existing product and data services, to commercialize other internally developed services and products and find other potential investments to diversify our product pipeline, which is the recent investments we have made in the diabetes space. As you know, diabetes is a large market with over 35 million people diagnosed in the United States, growing at 4% to 5% a year. In addition, 96 million people have prediabetes. To-date, our diabetes portfolio includes investments and a distribution agreement with Mellitus, whose platform Insulin Insights offers an algorithm that helps primary care physicians titrate insulin for type 2 diabetic patients. This partnership gives us exclusive marketing rights in the United States and Puerto Rico. Initial installations and new sales continue to make progress. Revenues have started but are not yet material to date. Type 2 diabetics on insulin represented a difficult patient population to manage as these patients often have found oral therapy alone has not been enough to adequately control their blood glucose. Insulin if incorrectly dosed can cause complications that can lead to emergency room visits and unplanned hospitalization. Primary care physicians find value with Insulin Insights because by approximately easily adjusting insulin levels in type 2 diabetic patients, patients who have less risk of adverse complications with insulin use. Have improved control of their blood glucose levels, we're pleased with fewer complications from diabetes and overall better clinical outcomes. In addition, plans have the potential to save on total cost of care and medication costs, as well as achieving higher [indiscernible] star quality measures as patients have improved HbA1c levels, demonstrating that their diabetes is under good control. In December 2022, we announced a commitment to invest up $5 million in Monarch, a privately held company through the purchase of a senior secured convertible promissory notes. Repayment of the note is secured by first priority interest in all of Monarch assets. Monarch is a digital health company whose proprietary endo tool glucose management system offers a technology-enabled approach to inpatient glycemic management. The Software-as-a-Service solution if FDA 510(k) cleared, patent protected and installed in more than 100 health systems across the United States. As of December 31, 2022, Monarch had borrowed $3.5 million out of the $5 million committed principal amount of the notes. In addition, $500,000 has been drawn post year-end. Although we do not have any distribution agreement in place with Monarch, we believe our recent investment provides us the opportunity to round out our diabetes portfolio and complement our outpatient diabetes management tool with its approach to improve inpatient diabetes management. In closing, I want to reiterate that regardless of policy changes affecting reimbursement and other market forces beyond our control, our fundamental value to our customers is and always has been the clinical value of earlier diagnosis of chronic progressive cardiovascular condition and improved simpler management of diabetes. Despite the changes that will always exist in health care reimbursement, there will still be patients, physicians, facilities and payers. Our offerings have a strong clinical value that all of these stakeholders will need in order to improve clinical outcomes and reduce health care costs. Because we have developed technology that is portable and accessible, we are also part of this solution to reduce health inequity that currently exists in cardiovascular disease. Our management team has the experience and resilience to make appropriate adjustments to our ongoing growth strategy as market conditions change. We also understand that changes in government policy may take time to be fully implemented. We are confident that our mission to improve clinical outcomes and reduce total cost of care in patients with cardiovascular disease and diabetes will remain relevant to our stakeholders for the foreseeable future. As Wayne mentioned, we'll be presenting and taking one-on-one meetings at the upcoming 22nd Annual Needham Virtual Health Care Conference on April 18, 2023. Thank you for your interest in the company and your continuing support. Now operator, please open the line. Doug, Wayne, Andy, Dennis and I will be happy to address your questions.
