Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES The Company has a line of credit with a financial institution totaling $85 million for the issuance of letters of credit (the “Letter of Credit Line”). The Letter of Credit Line, which is renewed annually, matures on November 17, 2015. The Company can also issue letters of credit under its senior unsecured revolving credit facility. For further discussion regarding the Company's senior unsecured revolving credit facility, see Note 13 to the consolidated financial statements in the Company's 2014 Annual Report on Form 10-K. In support of its risk management program, to ensure the Company’s performance or payment to third parties, $68 million in letters of credit, principally associated with the Letter of Credit Line, were outstanding at March 31, 2015. The letters of credit primarily represent collateral for current and future automobile liability and workers’ compensation loss payments. Contingent Lease Obligations The Company remains subject to contingent obligations under certain real estate leases that were entered into by certain predecessor companies of a subsidiary prior to the Company's acquisition of the subsidiary. No liability has been recorded for any of these potential contingent obligations. See Note 17 to the consolidated financial statements contained in the Company’s 2014 Annual Report on Form 10-K for further details. Settlements In 2010, a purported class action entitled In re Celera Corp. Securities Litigation was filed in the United States District Court for the Northern District of California against Celera Corporation and certain of its directors and current and former officers. An amended complaint filed in October 2010 alleges that from April 2008 through July 22, 2009, the defendants made false and misleading statements regarding Celera's business and financial results with an intent to defraud investors. The complaint was further amended in 2011 to add allegations regarding a financial restatement. The amended complaint seeks unspecified damages on behalf of an alleged class of purchasers of Celera's stock during the period in which the alleged misrepresentations were made. The Company's motion to dismiss the complaint was denied. Celera and the director and officer defendants have reached an agreement to settle this action, which the court has preliminarily approved. The settlement is fully covered by insurance. Legal Matters The Company is involved in various legal proceedings. Some of the proceedings against the Company involve claims that could be substantial in amount. In addition to the matters described below, in the normal course of business, the Company has been named, from time to time, as a defendant in various legal actions, including arbitrations, class actions and other litigation, arising in connection with the Company's activities as a provider of diagnostic testing, information and services. These legal actions may include lawsuits alleging negligence or other similar legal claims. These actions could involve claims for substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages, and could have an adverse impact on the Company's client base and reputation. The Company is also involved, from time to time, in other reviews, investigations and proceedings by governmental agencies regarding the Company's business, including, among other matters, operational matters, which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief. The number of these reviews, investigations and proceedings has increased in recent years with regard to many firms in the healthcare services industry, including the Company. In August 2011, the Company received a subpoena from the U.S. Attorney for the Northern District of Georgia seeking various business records, including records related to the Company's compliance program, certain marketing materials, certain product offerings, and test ordering and other policies. The Company is cooperating with the request. In June 2010, the Company received a subpoena from the Florida Attorney General's Office seeking documents relating to the Company's pricing and billing practices as they relate to Florida’s Medicaid program. The Company cooperated with the requests. In November 2013, the State of Florida intervened as a plaintiff in a civil lawsuit, Florida ex rel. Hunter Laboratories LLC v. Quest Diagnostics Incorporated, et al., filed in Florida Circuit Court. The suit, originally filed by a competitor laboratory, alleges that the Company overcharged Florida’s Medicaid program. The Company's motion to dismiss the state's amended complaint was denied. In April 2015, a qui tam civil lawsuit entitled United States ex rel. Mayes v. Berkeley HeartLab, Inc., et al., filed in the U.S. District Court for the District of South Carolina, was unsealed. The complaint alleges that certain alleged business practices of the defendants violate the False Claims Act, and seeks monetary relief. The United States has intervened as a plaintiff as to Berkeley HeartLab, Inc., a subsidiary of the Company; the United States did not intervene as a plaintiff as to Quest Diagnostics Incorporated. Before the lawsuit was unsealed, Berkeley HeartLab and Quest Diagnostics Incorporated had received subpoenas, civil investigative demands and interrogatories related to the matter. The federal or state governments may bring claims based on the Company's current practices, which it believes are lawful. In addition, certain federal and state statutes, including the qui tam provisions of the federal False Claims Act, allow private individuals to bring lawsuits against healthcare companies on behalf of government or private payers. The Company is aware of lawsuits, and from time to time has received subpoenas, related to billing practices based on the qui tam provisions of the Civil False Claims Act or other federal and state statutes, regulations or other laws. The Company understands that there may be other pending qui tam claims brought by former employees or other "whistle blowers" as to which the Company cannot determine the extent of any potential liability. Management cannot predict the outcome of such matters. Although management does not anticipate that the ultimate outcome of such matters will have a material adverse effect on the Company's financial condition, given the high degree of judgment involved in establishing loss estimates related to these types of matters, the outcome of such matters may be material to the Company's results of operations or cash flows in the period in which the impact of such matters is determined or paid. These matters are in different stages. Some of these matters are in their early stages. Matters may involve responding to and cooperating with various government investigations and related subpoenas. As of March 31, 2015, the Company does not believe that any losses related to the legal matters described above are probable. While the Company believes that a reasonable possibility exists that losses may have been incurred related to the legal matters described above, based on the nature and status of these matters, potential losses, if any, cannot be estimated. Reserves for Legal Matters Reserves for legal matters, other than those described above, totaled $12 million and $11 million at March 31, 2015 and December 31, 2014, respectively. Reserves for General and Professional Liability Claims As a general matter, providers of clinical testing services may be subject to lawsuits alleging negligence or other similar legal claims. These suits could involve claims for substantial damages. Any professional liability litigation could also have an adverse impact on the Company's client base and reputation. The Company maintains various liability insurance coverages for, among other things, claims that could result from providing, or failing to provide, clinical testing services, including inaccurate testing results, and other exposures. The Company's insurance coverage limits its maximum exposure on individual claims; however, the Company is essentially self-insured for a significant portion of these claims. Reserves for such matters, including those associated with both asserted and incurred but not reported claims, are established by considering actuarially determined losses based upon the Company's historical and projected loss experience. Such reserves totaled approximately $113 million at both March 31, 2015 and December 31, 2014. Management believes that established reserves and present insurance coverage are sufficient to cover currently estimated exposures. Management cannot predict the outcome of any claims made against the Company. Although management does not anticipate that the ultimate outcome of any such proceedings or claims will have a material adverse effect on the Company's financial condition, given the high degree of judgment involved in establishing accruals for loss estimates related to these types of matters, the outcome may be material to the Company's results of operations or cash flows in the period in which the impact of such claims is determined or paid.
