Commitments and Contingencies Disclosure [Abstract]
Litigation	Litigation The Company, in the normal course of business, is a party to various claims and other legal proceedings. In the opinion of management, the Company has legal defenses and/or insurance coverage (subject to deductibles) with respect to all of its pending legal actions. If management believes that a material loss not covered by insurance arising from these actions is probable and can reasonably be estimated, the Company may record the amount of the estimated loss or, if a loss cannot be estimated but the minimum liability may be estimated using a range and no point is more probable than another, the Company may record the minimum estimated liability. As additional information becomes available, any potential liability related to these actions is assessed and the estimates are revised, if necessary. Management believes that the ultimate outcome of all pending legal actions, individually and in the aggregate, will not have a material adverse effect on the Company's financial position that is inconsistent with its loss reserves or on its overall trends in results of operations. However, litigation and claims are subject to inherent uncertainties and unfavorable outcomes can occur that exceed any amounts reserved for such losses. If an unfavorable outcome were to occur, there exists the possibility of a material adverse impact on the results of operations in the period in which the outcome occurs or in future periods. On May 24, 2012, a complaint was filed against the Company in the United States District Court for the District of New Jersey alleging, among other things, that the Company failed to pay overtime compensation to a purported class of certain independent contractor examiners who, the complaint alleged, should be treated as employees for purposes of federal law. The complaint sought an award of an unspecified amount of allegedly unpaid overtime wages to certain examiners. The Company filed an answer denying the substantive allegations therein. On August 1, 2014, the Magistrate Judge issued a Report and Recommendation to conditionally certify the class of all contract examiners from August 16, 2010, to the present. On August 29, 2014, the Company submitted its objections to the Report and Recommendation of the Magistrate Judge. The Magistrate suspended ruling concerning those objections while the parties pursued the possibility of a settlement. On April 29, 2016, the Company reached a preliminary understanding with the plaintiffs with respect to a settlement of the lawsuit involving a release of all claims by the plaintiffs and the Company's establishment of a settlement fund of $0.45 million. Accordingly, as of September 30, 2016, the Company had accrued $0.45 million related to this matter versus $0.3 million as of December 31, 2015. The litigation accrual for all periods was included in the other current liabilities line item on the condensed consolidated balance sheet. The additional expense of $0.15 million recorded during the nine month period ended September 30, 2016, is included in the discontinued operations line item on the condensed consolidated statements of operations. On August 5, 2016, the Magistrate approved the parties’ definitive settlement agreement. The claim is not covered by insurance, and the Company incurred legal costs to defend the litigation which are recorded in discontinued operations. This matter relates to the former Portamedic service line for which the Company retained liability.

Litigation

The Company, in the normal course of business, is a party to various claims and other legal proceedings. In the opinion of management, the Company has legal defenses and/or insurance coverage (subject to deductibles) with respect to all of its pending legal actions. If management believes that a material loss not covered by insurance arising from these actions is probable and can reasonably be estimated, the Company may record the amount of the estimated loss or, if a loss cannot be estimated but the minimum liability may be estimated using a range and no point is more probable than another, the Company may record the minimum estimated liability. As additional information becomes available, any potential liability related to these actions is assessed and the estimates are revised, if necessary. Management believes that the ultimate outcome of all pending legal actions, individually and in the aggregate, will not have a material adverse effect on the Company's financial position that is inconsistent with its loss reserves or on its overall trends in results of operations. However, litigation and claims are subject to inherent uncertainties and unfavorable outcomes can occur that exceed any amounts reserved for such losses. If an unfavorable outcome were to occur, there exists the possibility of a material adverse impact on the results of operations in the period in which the outcome occurs or in future periods.
