Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business Description and Basis of Presentation [Text Block]	BASIS OF PRESENTATION These Unaudited Consolidated Financial Statements should be read in conjunction with the Audited Consolidated Financial Statements, including the notes thereto, and other information included in the Annual Report on Form 10-K of BioScrip, Inc. and subsidiaries (the “Company”) for the year ended December 31, 2011 (the “Form 10-K”) filed with the U.S. Securities and Exchange Commission. These Unaudited Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information, and the instructions to Form 10-Q and Article 10 of Regulation S-X promulgated under the Securities Exchange Act of 1934, as amended. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The information furnished in these Unaudited Consolidated Financial Statements reflects all adjustments, including normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the results for the interim periods presented. Operating results for the three months ended March 31, 2012 are not necessarily indicative of the results that may be expected for the full year ended December 31, 2012. The accounting policies followed for interim financial reporting are similar to those disclosed in Note 2 of the Audited Consolidated Financial Statements included in the Form 10-K. The Unaudited Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in the consolidation. As a result of the Company entering into a purchase agreement on February 1, 2012 with respect to the sale of its traditional and specialty pharmacy mail operations and community retail pharmacy stores (see Note 2), the Company reevaluated its segments in accordance with the provisions of Accounting Standards Codification (“ASC”) Topic 280, Segment Reporting (“ASC 280”). Based on its review, the Company changed its operating and reportable segments from “Infusion/Home Health Services” and “Pharmacy Services” to its new operating and reportable segments: “Infusion Services", "Home Health Services” and “PBM Services”. These three new operating and reportable segments reflect how the Company's chief operating decision maker reviews the Company's results in terms of allocating resources and assessing performance. As a result, prior period disclosures reflect the change in operating and reportable segments. Refer to Note 9 for more information. Certain prior period amounts have been reclassified to conform to the current year presentation. Such reclassifications have no material effect on the Company's previously reported consolidated financial position, results of operations or cash flow. The Company has evaluated events that occurred during the period subsequent to the balance sheet date through the filing date of this Form 10-Q. Refer to Note 13 for more information.

These Unaudited Consolidated Financial Statements should be read in conjunction with the Audited Consolidated Financial Statements, including the notes thereto, and other information included in the Annual Report on Form 10-K of BioScrip, Inc. and subsidiaries (the “Company”) for the year ended December 31, 2011 (the “Form 10-K”) filed with the U.S. Securities and Exchange Commission. These Unaudited Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information, and the instructions to Form 10-Q and Article 10 of Regulation S-X promulgated under the Securities Exchange Act of 1934, as amended. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.

The information furnished in these Unaudited Consolidated Financial Statements reflects all adjustments, including normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the results for the interim periods presented. Operating results for the three months ended March 31, 2012 are not necessarily indicative of the results that may be expected for the full year ended December 31, 2012. The accounting policies followed for interim financial reporting are similar to those disclosed in Note 2 of the Audited Consolidated Financial Statements included in the Form 10-K.

The Unaudited Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in the consolidation.

As a result of the Company entering into a purchase agreement on February 1, 2012 with respect to the sale of its traditional and specialty pharmacy mail operations and community retail pharmacy stores (see Note 2), the Company reevaluated its segments in accordance with the provisions of Accounting Standards Codification (“ASC”) Topic 280, Segment Reporting (“ASC 280”). Based on its review, the Company changed its operating and reportable segments from “Infusion/Home Health Services” and “Pharmacy Services” to its new operating and reportable segments: “Infusion Services", "Home Health Services” and “PBM Services”. These three new operating and reportable segments reflect how the Company's chief operating decision maker reviews the Company's results in terms of allocating resources and assessing performance. As a result, prior period disclosures reflect the change in operating and reportable segments. Refer to Note 9 for more information.

Certain prior period amounts have been reclassified to conform to the current year presentation. Such reclassifications have no material effect on the Company's previously reported consolidated financial position, results of operations or cash flow.

The Company has evaluated events that occurred during the period subsequent to the balance sheet date through the filing date of this Form 10-Q. Refer to Note 13 for more information.
