Accounting Policies [Abstract]
Basis of Presentation	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, 2021 and December 31, 2020, and the results of operations, comprehensive income, and cash flows for the three months ended March 31, 2021 and 2020. 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, 2020, filed with the SEC on February 24, 2021, except as discussed in the section entitled “Recently Adopted Authoritative Guidance” below. The Company’s results of operations, comprehensive income, and cash flows for the three months ended March 31, 2021 are not necessarily indicative of results that may be expected for the year ending December 31, 2021, or for any future period.
Principles of Consolidation	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.
Reclassifications and Adjustments	Reclassifications and AdjustmentsCertain prior-year amounts have been reclassified to conform with current-period presentation.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Company’s Condensed Consolidated Financial Statements and accompanying Notes. Management bases its estimates on historical experience and various other assumptions believed 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, 2021, 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	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 and Issued Authoritative Guidance	Recently Adopted Authoritative Guidance In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The update simplifies the accounting for income taxes by removing certain exceptions to the general principles in Accounting Standards Codification (“ASC”) 740, Income Taxes, as well as improves consistent application of and simplifies the guidance for other areas of ASC 740 by clarifying and amending existing guidance. The Company adopted ASU 2019-12 on January 1, 2021 on a prospective basis. The adoption of this guidance did not have a material impact on the Company’s Condensed Consolidated Financial Statements. Recently Issued Authoritative Guidance In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40). The update simplifies the accounting for convertible debt instruments by reducing the number of accounting models and the number of embedded conversion features that could be recognized separately from the primary contract. ASU 2020-06 also enhances transparency and improves disclosures for convertible instruments and earnings per share guidance. This update permits the use of either the modified retrospective or fully retrospective method of transition. ASU 2020-06 will be effective for the Company beginning January 1, 2022. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently evaluating the impact ASU 2020-06 will have on its Condensed Consolidated Financial Statements. There was no other 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.
Business Combinations	The Company accounted for the acquisition of the 340B Link Business in accordance with ASC 805, Business Combinations. The tangible and intangible assets acquired and liabilities assumed were recorded at fair value on the acquisition date. The preliminary fair values assume management's best estimates based on information available at the acquisition date and may change over the measurement period, which will end no later than one year from the acquisition date, as additional information is received.Intangible assets eligible for recognition separate from goodwill were those that satisfied either the contractual/legal criterion or the separability criterion in the accounting guidance. The customer relationships intangible asset represents the fair value of the underlying relationships and agreements with the 340B Link Business’s customers. The acquired technology intangible asset represents the fair value of the 340B Link Business's portfolio of software and solutions that have reached technological feasibility and were part of the 340B Link Business’s offerings at the date of acquisition. The trade names intangible asset represents the fair value of brand and name recognition associated with the marketing of the 340B Link Business's software-enabled services and solutions. The non-compete agreements intangible asset represents the fair value of non-compete agreements with former key members of the 340B Link Business's management. The fair value of the customer relationships intangible asset was determined based on the excess earnings method; the fair values of the acquired technology and trade names intangible assets were determined based on the relief-from-royalty method; and the fair value of the non-compete agreements intangible asset was determined based on the lost profits method. The key assumptions used in estimating the fair values of intangible assets included forecasted financial information; customer attrition rates; royalty rates of 10.0% and 0.5% for the acquired technology and trade names intangible assets, respectively; a discount rate of 14.0% for all intangible assets; and certain other assumptions. The customer relationships and acquired technology intangible assets are being amortized using a double-declining method of amortization as such method better represents the economic benefits to be obtained. The trade names and non-compete agreements are being amortized over their estimated useful lives using the straight-line method of amortization. The Company believes that the fair value assigned to the assets acquired and liabilities assumed are based on reasonable assumptions and estimates that market participants would use. Actual results may differ from these estimates and assumptions.
Revenue Recognition	Revenue Recognition The Company earns revenues from sales of its products and related services, which are sold in the healthcare industry, its principal market. The Company’s customer arrangements typically include one or more of the following revenue categories: Connected devices, software licenses, and other. Software-enabled connected devices and software licenses that manage and regulate the storage and dispensing of pharmaceuticals, consumables blister cards, and packaging equipment and other supplies. This revenue category is often sold through long-term, sole-source agreements with multi-year co-development plans. Solutions in this category include, but are not limited to, XT Series automated dispensing systems, the XR2 Automated Central Pharmacy system, and IV compounding automation solutions. Technical services. Post-installation technical support and other related services, including phone support, on-site service, parts, and access to unspecified software updates and enhancements, if and when available. This revenue category is often supported by multi-year or annual contractual agreements. Consumables. Medication adherence packaging, labeling, and other one-time use packaging including multimed adherence packaging and single dose blister cards which are used by retail, community, and outpatient pharmacies, as well as by institutional pharmacies serving long-term care and other sites outside the acute care hospital, and are designed to improve patient engagement and adherence to prescriptions. Software-as-a-service (“SaaS”), subscription software, and technology-enabled services. Emerging software and service solutions which are offered on a subscription basis with fees typically based either on transaction volume or a fee over a specified period of time. Solutions in this category include, but are not limited to, EnlivenHealth™ (formerly Population Health Solutions), 340B solutions, and services associated with Omnicell One™ (formerly Performance Center), Central Pharmacy Dispensing Services, including the XR2 Automated Central Pharmacy system, and Central Pharmacy Compounding Services, including IV compounding automation solutions.
Net Income (Loss) Per Share	Basic net income per share is computed by dividing net income for the period by the weighted-average number of shares outstanding during the period. In periods of net loss, all potential common shares are anti-dilutive, so diluted net loss per share equals the basic net loss per share. In periods of net income, diluted net income per share is computed by dividing net income for the period by the basic weighted-average number of shares plus any dilutive potential common stock outstanding during the period, using the treasury stock method. Potential common stock includes the effect of outstanding dilutive stock options, restricted stock awards, and restricted stock units, as well as shares the Company could be obligated to issue from its convertible senior notes and warrants, as described in Note 10, Convertible Senior Notes. Any anti-dilutive weighted-average dilutive shares related to stock award plans, convertible senior notes, and warrants are excluded from the computation of the diluted net income per share.
Fair Value Hierarchy	The Company measures its financial instruments at fair value. The Company’s cash, cash equivalents, and restricted cash are classified within Level 1 of the fair value hierarchy as they are valued primarily using quoted market prices utilizing market observable inputs. The Company's credit facility is classified within Level 2 as the valuation inputs are based on quoted prices or market observable data of similar instruments. The Company's convertible senior notes are classified within Level 2 as the valuation inputs are based on quoted prices in an inactive market on the last day in the reporting period.
Convertible Debt	Convertible debt instruments that may be settled in cash are required to be separated into liability and equity components. The allocation to the liability component is based on the fair value of a similar instrument that does not contain an equity conversion option. Based on this debt-to-equity ratio, debt issuance costs are then allocated to the liability and equity components in a similar manner.
Commitments and Contingencies	As required under ASC 450, Contingencies, the Company accrues for contingencies when it believes that a loss is probable and that it can reasonably estimate the amount of any such loss. The Company has not recorded any material accrual for contingent liabilities associated with the legal proceedings described above based on its belief that any potential loss, while reasonably possible, is not probable. Further, any possible range of loss in these matters cannot be reasonably estimated at this time or is not deemed material. The Company believes that it has valid defenses with respect to these legal proceedings pending against it. However, litigation is inherently unpredictable, and it is possible that cash flows or results of operations could be materially affected in any particular period by the unfavorable resolution of any of these legal proceedings or because of the diversion of management’s attention and the creation of significant expenses.
