Accounting Policies [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION Integer Holdings Corporation (together with its consolidated subsidiaries, “Integer” or the “Company”) is a publicly-traded corporation listed on the New York Stock Exchange under the symbol “ITGR.” Integer is one of the largest medical device outsource manufacturers in the world serving the cardiac, neuromodulation, vascular, orthopedics, advanced surgical and portable medical markets. The Company provides innovative, high-quality medical technologies that enhance the lives of patients worldwide. In addition, it develops batteries for high-end niche applications in the energy, military, and environmental markets. The Company’s reportable segments are: (1) Medical and (2) Non-Medical. The Company’s customers include large multi-national original equipment manufacturers (“OEMs”) and their affiliated subsidiaries. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information (Accounting Standards Codification (“ASC”) 270, Interim Reporting) and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all of the information necessary for a full presentation of financial position, results of operations, and cash flows in conformity with GAAP. In the opinion of management, the condensed consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the results of the Company for the periods presented. Intercompany transactions and balances have been fully eliminated in consolidation. Operating results for interim periods are not necessarily indicative of results that may be expected for the fiscal year as a whole. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, certain components of equity, sales, expenses, and related disclosures at the date of the financial statements and during the reporting period. Actual results could differ materially from these estimates. For further information, refer to the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. The first quarter of 2021 ended on April 2 and consisted of 92 days, and the first quarter of 2020 ended on April 3 and consisted of 94 days. Risks and Uncertainties Beginning in early March 2020, the global spread of the novel coronavirus (“COVID-19”) created significant uncertainty and worldwide economic disruption. Specific impacts to the Company’s business include delayed or reduced customer orders and sales, restrictions on its associates’ ability to travel or work, delays in shipments to and from certain countries, and disruptions in its supply chain. The extent to which COVID-19 impacts the Company’s operations will depend on future developments, which are highly uncertain and difficult to predict, including, among others, the duration of the outbreak, the effectiveness and utilization of vaccines for COVID-19 and its variants, new information that may emerge concerning the severity of COVID-19 and the actions, especially those taken by governmental authorities to contain the pandemic or treat its impact. As pandemic-related events continue to evolve, additional impacts may arise that the Company is not aware of currently. Any prolonged material disruption of the Company’s associates, suppliers, manufacturing, or customers could materially impact its consolidated financial position, results of operations or cash flows. Recent Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standard Updates (“ASU”) issued by the Financial Accounting Standards Board ("FASB"). The Company evaluated all recent accounting pronouncements issued, including those that are currently effective, and determined that the adoption of these pronouncements would not have a material effect on the financial position, results of operations or cash flows of the Company. There have been no new or material changes to the significant accounting policies discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, that are of significance, or potential significance, to the Company.
