Subsequent Events [Abstract]
Subsequent Events	Between January 3, 2017 and March 29, 2017, an aggregate of 6,280 shares of Series H Preferred Stock was converted into 2,325,929 shares of the Company’s common stock, and 2,778 shares of common stock were issued to an employee as compensation. On September 27, 2016, a tax warrant was issued against the Company by the Florida Department of Revenue (the “DOR”) for unpaid state income taxes in the approximate amount of $0.9 million, including penalties and interest. On January 25, 2017, the Company paid the DOR $250,000 as partial payment on this liability, and in February 2017 the Company entered into a stipulation agreement with the DOR which will allow the Company to pay the remainder of the amount due to the DOR over a period of 12 months. If at any time during the stipulation period the Company fails to timely file any required tax returns with the DOR or does not meet the payment obligations under the stipulation agreement, the entire amount due will be accelerated. In December of 2016, TCS-Florida, L.P. (“Tetra”), filed suit against the Company for failure to make the required payments under an equipment leasing arrangement that the Company had with Tetra (see note 9). On January 3, 2017, Tetra received a default judgment against the Company in the amount of $2.6 million, representing the balance owed on the lease, as well as additional interest, penalties and fees. The Company has recognized this amount in its consolidated financial statements as of December 31, 2016. In January and February of 2017, the Company made payments to Tetra in connection with this judgment aggregating to $0.7 million, and on February 15, 2017 the Company entered into a forbearance agreement with Tetra whereby the remaining $1.9 million due under the default judgment would be paid in 24 equal monthly installments, commencing on May 1, 2017. In December of 2016, DeLage Landen Financial Services, Inc. (“DeLage”), filed suit against the Company for failure to make the required payments under an equipment leasing arrangement that the Company had with DeLage (see note 9). On January 24, 2017, DeLage received a default judgment against the Company in the approximate amount of $1.0 million, representing the balance owed on the lease, as well as additional interest, penalties and fees. The Company has recognized this amount in its consolidated financial statements as of December 31, 2016. On February 8, 2017, the Company entered into a payment agreement with DeLage whereby the amount due would be paid in variable monthly installments through January of 2019, with an implicit interest rate of 4.97%. On January 13, 2017, the Company completed an asset purchase agreement to acquire certain assets related to Scott County Community Hospital, based in Oneida, Tennessee (the “Hospital Assets”). The Hospital Assets include a 52,000 square foot hospital building and 6,300 square foot professional building on approximately 4.3 acres. Scott County Community Hospital is classified as a Critical Access Hospital (rural). The Company acquired the Hospital Assets out of bankruptcy for a purchase price of $1.0 million. The Company intends to reopen the hospital during the second or third quarter of 2017, subject to the receipt of the necessary licenses and regulatory approvals. On February 2, 2017, the Company issued $1.6 million aggregate principal amount of Original Issue Discount Convertible Debentures due three months from the date of issuance (the “February Debentures”) and warrants to purchase an aggregate of 100,000 shares of common stock, which can be exercised at any time after August 17, 2017 at an exercise price of $2.58 per share (the “Warrants”), to an accredited investor for a purchase price of $1.5 million. The Debentures were convertible at a conversion price of $2.58 per share (subject to adjustment). On February 22, 2017, the Reverse Stock Split became effective (see note 1). The Reverse Stock Split resulted in the issuance of 7,897 shares of common stock due to the rounding up of fractional shares. In January and February of 2017, the Company received advances aggregating $3.3 million from Mr. Diamantis. The advances, along with $0.5 million of previously accrued but unpaid interest, were due on demand, bearing interest at 10% per annum. The Company used the advances to pay the purchase price for the Hospital Assets and for general corporate purposes. On March 7, 2017, the Company issued a promissory note to Mr. Diamantis in the amount of $3.8 million (the “2017 Diamantis Note”) in connection with these advances received in 2017, plus accrued and unpaid interest of $0.5 million. On March 13, 2017, the September 2016 Notes, along with the accompanying warrants, were exchanged for 400,000 shares of the Company’s common stock. On March 21, 2017, the Company, under the terms of an exchange agreement with a holder of previously issued warrants to purchase the Company’s common stock, issued 29,518 shares of common stock in exchange for the warrants. On March 21, 2017, the Company issued $10.85 million aggregate principal amount of Senior Secured Original Issue Discount Convertible Debentures due March 21, 2019 (the “Convertible Debentures”) and three series of warrants to purchase an aggregate of 19,608,435 shares of the Company’s common stock to several accredited investors. The Company received net proceeds from this transaction in the approximate amount of $8.4 million. The Company used $3.8 million of the net proceeds to repay the 2017 Diamantis Note and $0.75 million of the net proceeds to make a partial repayment on the TCA Debenture. The remainder of the net proceeds is being used for general corporate purposes. In conjunction with the issuance of the Convertible Debentures, the holder of the February Debentures exchanged these debentures for $2.5 million of new debentures (the “Exchange Debentures” and, collectively with the Convertible Debentures, the “Debentures”) on the same terms as, and pari passu with, the Convertible Debentures and warrants. Additionally, the holders of an aggregate of $2.2 million stated value of the Company’s Series H Preferred Stock exchanged such preferred stock into $2.7 million principal amount of Exchange Debentures and warrants. All of the Debentures contain a 24% original issue discount. The Debentures are convertible into shares of the Company’s common stock at an initial conversion price of $1.66 per share, subject to adjustment as more fully described in the Debentures. The Debentures will begin to amortize monthly commencing on the 90^thday following the closing date, except for the Exchange Debentures related to the Series H Preferred Stock, which began to amortize monthly on the closing date. On each monthly amortization date, the Company may elect to repay 5% of the original principal amount of Debentures in cash or, in lieu thereof, the conversion price of such Debentures will thereafter be 85% of the volume weighted average price at the time of conversion. In the event the Company does not elect to pay such amortization amounts in cash, each investor, in their sole discretion, may increase the conversion amount subject to the alternative conversion price by up to four times the amortization amount. The Debentures contain customary affirmative and negative covenants. The conversion price is subject to reset in the event of offerings or other issuances of common stock, or rights to purchase common stock, at a price below the then conversion price, as well as other customary anti-dilution protections as more fully described in the Debentures. The Debentures are secured by all of the Company’s assets and are guaranteed by all of the Company’s subsidiaries. Between March 22, 2017 and March 27, 2017, holders of the Exchange Debentures converted an aggregate of $0.3 million of such Exchange Debentures into 215,171 shares of common stock. The Series A Warrants are immediately exercisable for up to a number of shares of our common stock equal to 100% of the shares underlying the Debentures and have a term of five years. The Series B Warrants are immediately exercisable for up to a number of shares of common stock equal to 100% of the shares underlying the Debentures for a period of 18 months. The Series C Warrants are exercisable for up to a number of shares of common stock equal to 100% of the shares underlying the Debentures and have a term of five years, however these Warrants only become exercisable if, when and to the extent that the holders exercise the Series B Warrants. The Series A and Series C Warrants each have an exercise price of $1.95 per share and the Series B Warrants have an exercise price of $1.66. All of the warrants are subject to reset in the event of offerings or other issuances of common stock, or rights to purchase common stock, at a price below the then exercise price, as well as other customary anti-dilution protections. The Company is required to file a registration statement registering for resale the shares underlying the Debentures and warrants on or before April 7, 2017, and to use its best efforts to cause the registration statement to be declared effective within 45 days of filing, or within 75 days if the registration statement is reviewed. Additionally, the Company is required to seek shareholder approval to issue in excess of 20% of the Company’s issued and outstanding shares of common stock. In February 2017, the Company made a payment to TCA in the amount of $0.4 million. In conjunction with the issuance of the Convertible Debentures on March 21, 2017, the Company entered into a letter agreement with TCA, which (i) waives any payment defaults through March 21, 2017; (ii) provides for the $0.75 million payment discussed above; (iii) sets forth a revised repayment schedule whereby the remaining principal plus interest aggregating to approximately $2.6 million is repaid in various monthly installments from April of 2017 through September of 2017; and (iv) provides for payment of an additional service fee in the amount of $150,000. In addition, TCA entered into an intercreditor agreement with the purchasers of the Convertible Debentures which sets forth rights, preferences and priorities with respect to the security interests in the Company’s assets. The Company’s Epinex Diagnostics Laboratories, Inc. subsidiary had been sued in a California state court by two former employees who alleged that they were wrongfully terminated, as well as for a variety of unpaid wage claims. The parties entered into a settlement agreement of this matter on July 29, 2016 for approximately $0.2 million, and the settlement was consummated on August 25, 2016. In October of 2016, the plaintiffs in this matter filed a motion with the court seeking payment for attorneys’ fees in the approximate amount of $0.7 million. On March 24, 2017, the court granted plaintiffs’ motion for payment of attorneys’ fees in the amount of $0.3 million, and the Company has accrued this amount in its consolidated financial statements.
