Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's income tax expense was not material for any period presented in the condensed consolidated statement of operations. No amounts were recorded for unrecognized tax benefits or for the payment of interest and penalties during the three-month periods ended March 31, 2018 and 2017. No federal or state tax benefits were recorded relating to the current year loss. The Company continues to believe that a full valuation allowance is required on its net deferred tax assets, with the exception of deferred income tax on the liabilities of certain indefinite-lived intangibles. The tax years 2014 through 2017 may be subject to federal examination and assessment. Tax years from 2009 through 2013 remain open solely for purposes of federal and certain state examination of net operating loss ("NOL") and credit carryforwards. State income tax returns may be subject to examination for tax years 2013 through 2017, depending on state tax statute of limitations. As of December 31, 2017, the Company had U.S. federal and state net operating loss carryforwards of $19.9 million and $19.3 million, respectively. There has been no significant change in these balances as of March 31, 2018. The net operating loss carryforwards, if not utilized, will expire in the years 2018 through 2037. No tax benefit has been reported since a full valuation allowance offsets these tax attributes. However, limitations could apply upon the release of the valuation allowance. Since the Company had changes in ownership during 2015, continuing into 2016 and 2017, the Company has determined that additional limitations under IRC Section 382 of the Internal Revenue Code of 1986 apply to the future utilization of certain tax attributes including NOL carryforwards, other tax carryforwards, and certain built-in losses. Limitations on future net operating losses apply when a greater than 50% ownership change over a three-year period occurs under the rules of IRC Section 382. The Company has not had a formal study completed with respect to IRC Section 382; however, the Company did complete its own analysis and determined that there has been a greater than 50% change in ownership following the Merger on May 11, 2017. The allowance of future net operating losses is limited to the market capitalization value multiplied by the “long-term tax-exempt rate” as of May 2017, the month in which the ownership change took place. It is estimated that the Company will be limited to approximately $0.2 million of NOL per year, and due to expiring net operating loss provisions, the Company has estimated it will be unable to utilize approximately $173.1 million and $140.4 million of remaining federal and state net operating losses, respectively, in the future. The net operating loss carryforwards expiring prior to utilization as a result of the Section 382 limitations reduce the deferred tax assets, with a corresponding reduction of the valuation allowance. In addition to the Company’s existing net operating losses, the Company is confirming that the net operating losses of PHS are acquired as part of the Merger, satisfying the continuity of business requirements. PHS has an estimated $1.87 million and $1.86 million of federal and state net operating losses, respectively, as of the Merger date after applying the limitations of IRC Section 382. Preliminary calculations indicate the PHS losses will be limited to $0.09 million of NOL per year. Tax reform legislation commonly known as the Tax Cuts and Jobs Act (“Tax Act”) was signed into law on December 22, 2017, and included a shift to a flat federal corporate income tax rate of 21% effective in the first quarter of 2018. The statutory rate was 35% for the period ending March 31, 2017. The SEC staff issued Staff Accounting Bulletin No. 118 ("SAB 118"), which provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under Accounting Standards Codification 740 - Income Taxes ("ASC 740"). The Company completed a re-measurement of deferred income tax assets and liabilities as of December 31, 2017 and does not anticipate further adjustments to income tax expense as a result of the Tax Act.
