Accounting Policies [Abstract]
Organization and Summary of Significant Accounting Policies	Organization and Summary of Significant Accounting Policies Business Omnicell, Inc. was incorporated in California in 1992 under the name Omnicell Technologies, Inc. and reincorporated in Delaware in 2001 as Omnicell, Inc. The Company’s major products and related services are medication management solutions and adherence tools for healthcare systems and pharmacies, which are sold in its principal market, the healthcare industry. The Company’s market is primarily located in the United States and Europe. “Omnicell” or the “Company” refer to Omnicell, Inc. and its subsidiaries, collectively. Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements reflect, in the opinion of management, all adjustments, consisting of normal recurring adjustments and accruals, necessary to present fairly the financial position of the Company as of March 31, 2023 and December 31, 2022, and the results of operations, comprehensive income (loss), and cash flows for the three months ended March 31, 2023 and 2022. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) have been condensed or omitted in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and accompanying Notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 1, 2023, except as discussed in the section entitled “Recently Adopted Authoritative Guidance” below. The Company’s results of operations, comprehensive income (loss), and cash flows for the three months ended March 31, 2023 are not necessarily indicative of results that may be expected for the year ending December 31, 2023, or for any future period. Principles of Consolidation The Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Company’s Condensed Consolidated Financial Statements and accompanying Notes. These estimates are based on historical experience and various other assumptions that management believes to be reasonable. Although these estimates are based on management’s best knowledge of current events and actions that may impact the Company in the future, actual results may be different from the estimates. The Company’s critical accounting policies are those that affect its financial statements materially and involve difficult, subjective, or complex judgments by management. As of March 31, 2023, the Company is not aware of any events or circumstances that would require an update to its estimates, judgments, or revisions to the carrying value of its assets or liabilities. Segment Reporting The Company manages its operations as a single segment for the purposes of assessing performance and making operating decisions. The Company’s Chief Operating Decision Maker (“CODM”) is its Chief Executive Officer. The CODM allocates resources and evaluates the performance of the Company at the consolidated level using information about its revenues, gross profit, income from operations, and other key financial data. All significant operating decisions are based upon an analysis of the Company as one operating segment, which is the same as its reporting segment. Recently Adopted Authoritative Guidance In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The update addresses diversity in practice by requiring that an acquirer recognize and measure contract assets and liabilities acquired in a business combination in accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers. The Company adopted ASU 2021-08 beginning January 1, 2023 and will apply the guidance prospectively to acquisitions occurring on or after the adoption date. Recently Issued Authoritative Guidance There was no recently issued and effective authoritative guidance that is expected to have a material impact on the Company’s Condensed Consolidated Financial Statements through the reporting date.
