Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On April 21, 2015, Omnicell International, Inc. (“Omnicell International”), a wholly-owned subsidiary of Omnicell, Inc., completed its acquisition of Mach 4 Automatisierungstechnik GmbH (“Mach4”) pursuant to the Agreement, dated February 26, 2015, by and among Apotheka Imedisa 2001 S.A., Holger Wallat, Dirk Rolf Beils and Peter Jansen (collectively, the “Selling Shareholders”) and Omnicell International (the “Share Purchase Agreement”). Pursuant to the Share Purchase Agreement, Omnicell International purchased the entire registered share capital of Mach4 from the Selling Shareholders for aggregate consideration of approximately $16.5 million, of which $2.7 million was placed in an escrow fund, which will ultimately be distributed to the Selling Shareholders (subject to claims that Omnicell International may have against the escrow fund for indemnification and other claims following the closing) (the “Acquisition”). In addition, Omnicell International will pay approximately $0.9 million to Mach4 for the payoff of existing debt of Mach4. The final purchase price remains subject to certain adjustments as provided for in the Share Purchase Agreement. On April 30, 2015, we closed our acquisition of Avantec Healthcare Limited (“Avantec”) pursuant to a share purchase agreement (the “Avantec Share Purchase Agreement”) among Omnicell, Inc. and the selling shareholders thereto (the “Avantec Selling Shareholders”) for the purchase of the entire issued share capital of Avantec not already owned by Omnicell, Inc. We previously owned 15% of the company and accounted for it under the equity method. Avantec develops medication and supply automation products that complement our solutions for configurations suited to the United Kingdom marketplace, and has been the exclusive distributor of our medication and supply automation solutions since 2005 in the United Kingdom. As a result of the Acquisition, we paid the Avantec Selling Shareholders an amount equal to $10.2 million in cash, subject to certain adjustments provided for in the Avantec Share Purchase Agreement, and retained an additional $1.8 million of the purchase price which will ultimately be distributed to the Avantec Selling Shareholders (subject to claims that we may have against such funds for indemnification and other claims following the closing). In addition, the Avantec Selling Shareholders will be entitled to receive up to an additional $3.0 million upon the achievement of bookings milestones for 2015 and an additional $3.0 million upon the achievement of bookings milestones for 2016. Both of these acquired companies will be in our Automation and Analytics segment. The valuations and related purchase price allocations for these acquisitions have not yet been completed.
