Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying unaudited consolidated financial statements have been prepared by Inovalon Holdings, Inc. (“Inovalon” or the “Company”) in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting and as required by Rule 10-01 of Regulation S-X. Accordingly, the unaudited consolidated financial statements may not include all of the information and notes required by GAAP for audited financial statements. The year-end December 31, 2020 consolidated balance sheet data included herein was derived from audited financial statements but does not include all disclosures required by GAAP for complete financial statements. In the opinion of the Company’s management, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of items of a normal and recurring nature, necessary to present fairly the Company’s financial position as of March 31, 2021, the results of operations, comprehensive income (loss), stockholders’ equity, and cash flows for the three-month periods ended March 31, 2021 and 2020. The results of operations for the three-month periods ended March 31, 2021 and 2020 are not necessarily indicative of the results to be expected for the full year. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts of assets and liabilities, and related disclosures, as of the date of the financial statements, and the amounts of revenue and expenses reported during the period. Actual results could differ from estimates. The information contained herein should be read in conjunction with the audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 (the “2020 Form 10-K”). The accompanying unaudited consolidated financial statements include the accounts of Inovalon and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company’s management considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated through the date of issuance of these financial statements.
Recently Adopted Accounting Standards and Recently Issued Accounting Standards	Recently Issued Accounting Standards There have been no developments to recently issued accounting standards, including the expected dates of adoption and estimated effects on the Company’s consolidated financial statements and note disclosures, from those disclosed in the 2020 Form 10-K, that would be expected to impact the Company.
