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 a medical device outsource manufacturer 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 accompanying condensed consolidated financial statements are presented in accordance with the rules and regulations of the United States ("U.S.") Securities and Exchange Commission ("SEC") and do not include all of the disclosures normally required by U.S. generally accepted accounting principles (“U.S. GAAP”) as contained in the Company’s Annual Report on Form 10-K. Accordingly, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s most recent Annual Report on Form 10-K for the fiscal year ended December 31, 2021. 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. The results for interim periods are not necessarily indicative of results or trends that may be expected for the fiscal year as a whole. The condensed consolidated financial statements were prepared using U.S. GAAP, which require 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. The second quarter and first six months of 2022 ended on July 1 and consisted of 91 days and 182 days, respectively. The second quarter and first six months of 2021 ended on July 2 and consisted of 91 days and 183 days, respectively. Reclassifications Certain prior period amounts have been reclassified to conform to current year presentation. Refer to Note 5, “Goodwill and Other Intangibles, Net,” for a description of the changes made to the Company’s prior period definite-lived asset classification to reflect the current year presentation. Refer to Note 14, “Segment Information,” for a description of the changes made to the Company’s prior period product line sales classification to reflect the current year presentation. Risks and Uncertainties Significant uncertainty remains as to the potential impact of the COVID-19 pandemic on the Company’s operations, and on the global economy. Specific impacts to the Company’s business included and continue to include labor shortages, disruptions in the supply chain, delayed or reduced customer orders and sales, restrictions on associates’ ability to travel or work, and delays in shipments to and from certain countries. The Company is uncertain of the future impact of the ongoing COVID-19 pandemic or recovery of prior deterioration in economic conditions to its sales channels, supply chain, manufacturing, and distribution. Additionally, the current conflict between Russia and Ukraine and the related sanctions and other penalties imposed by countries across the globe against Russia are creating substantial uncertainty in the global economy. While the Company does not have operations in Russia or Ukraine and does not have significant direct exposure to customers and vendors in those countries, it is unable to predict the impact that these actions will have on the global economy or on the Company’s financial condition, results of operations, and cash flows as of the date of these financial statements. 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, 2021, that are of significance, or potential significance, to the Company.
