Accounting Policies [Abstract]
Background and Basis of Presentation and Interim Financial Statements	Background and Basis of Presentation Avanos Medical, Inc., formerly Halyard Health, Inc., is a medical technology company that operates its business through its Medical Devices business segment. References to “Avanos,” “Company,” “we,” “our” and “us” refer to Avanos Medical, Inc. On April 30, 2018, we closed the sale of our S&IP business, including the name “Halyard Health” (and all variations thereof and related intellectual property rights). Accordingly, the Company’s name was changed from “Halyard Health, Inc.” to “Avanos Medical, Inc.” effective June 30, 2018. Avanos is a medical technology company focused on delivering clinically superior breakthrough medical device solutions to improve patients’ quality of life. We are committed to addressing some of today’s most important healthcare needs, such as reducing the use of opioids while helping patients move from surgery to recovery. Interim Financial Statements We prepared the accompanying condensed consolidated financial statements according to accounting principles generally accepted in the United States (“GAAP”) for interim financial information and the instructions to the Quarterly Report on Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements, and the condensed consolidated financial statements in this Quarterly Report on Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2017. Our unaudited interim condensed consolidated financial statements contain all necessary material adjustments, which are of a normal and recurring nature, to fairly state our financial condition, results of operations and cash flows for the periods presented.
Use of Estimates	Use of Estimates Preparation of our condensed consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting periods. Estimates are used in accounting for, among other things, distributor rebate accruals, future cash flows associated with impairment testing for goodwill and long-lived assets, loss contingencies, and deferred tax assets and potential income tax assessments. Actual results could differ from these estimates, and the effect of the difference could be material to our financial statements. Changes in these estimates are recorded when known.
Revenue Recognition	Revenue Recognition Sales revenue is recognized at a point in time, which is upon shipment or upon delivery of our products to unaffiliated customers, depending on shipping terms. Accordingly, control of the products transfers to the customer in accordance with the transaction's shipping terms. Sales revenue is recognized for the amount of consideration that we expect to be entitled to in exchange for our products. Sales are reported net of estimated cash discounts, returns, rebates and incentives, each as described below, and freight allowed. Taxes imposed by governmental authorities, such as sales taxes or value-added taxes, are excluded from net sales. We provide medical products to distributors or end-user customers under supply agreements under which customers may place purchase orders for a variety of our products at specified pricing over a specified term, usually three years. While our sales and marketing efforts are directed to hospitals or other healthcare providers, our products are generally sold through third-party distribution channels. Under our contracts with customers, our performance obligations are normally limited to shipment or delivery of products to a customer upon receipt of a purchase order. We bill our customers, depending on shipping terms, upon shipment or delivery of the products to the customer. Amounts billed are typically due within 30 days, with a 1% discount allowed for distributors if payment is made within 15 days. We estimate cash discounts based on historical experience and record the cash discounts as an allowance to trade receivables. The differences between estimated and actual cash discounts are normally not material. We allow for returns within a specified period of time following the customers' receipt of the goods and estimate an allowance to trade receivables for returns based on historical experience. The differences between estimated and actual returns are normally not material. Our contracts provide for forms of variable consideration including rebates, incentives and pricing tiers, each of which are described below: Rebates - We provide for rebates to distributors for estimated historical differences between list prices and average end-user customer prices and the quantity of products expected to be sold to specific end-user customers. We maintain a liability for the estimated rebates that have been earned but unpaid. Differences between estimated and actual rebates are normally not material. Incentives - Incentives include fees paid to group purchasing organizations ("GPOs") or distributors in conjunction with the sales of our products to end-user customers. We estimate our incentive liability based on historical experience. Differences between estimated and actual incentives are normally not material. Pricing tiers - In certain of our contracts, pricing is dependent on volumes purchased. Pricing is lower for customers who purchase higher volumes. Customers are placed in a pricing tier based on expected purchase volume, which is developed primarily using the customer's purchase history. Depending on the customer's purchases, we may move the customer up or down a tier. Pricing in the new pricing tier is applied to purchase orders prospectively. There are no retrospective adjustments based on movements between pricing tiers.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements Effective January 1, 2018, we adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, which provides a principles-based, five-step approach to measure and recognize revenue from contracts with customers. Adoption of this ASU requires substantial additional disclosures, but did not have a material effect on our financial position, results of operations or cash flows. Recently Issued Accounting Pronouncements In June 2018, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. This ASU expands the scope of Topic 718 to include accounting for share-based payments for acquiring goods and services from non-employees except for specific guidance on assumptions used in an option pricing model and expense attribution. ASU 2018-07 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018, with early adoption permitted. We currently do not have any stock-based instruments outstanding to non-employees and do not anticipate any such awards in the foreseeable future. Accordingly, we do not expect adoption of this ASU to have a material effect on our financial position, results of operations or cash flows. In February 2018, the FASB issued ASU No. 2018-02, Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU is intended to help companies reclassify certain stranded income tax effects in accumulated other comprehensive income (“AOCI”) resulting from the Tax Cuts and Jobs Act of 2017 (the “Act”), which was enacted in December 2017. ASU 2018-02 provides for the elimination of stranded tax effects of the Act by allowing reclassification of stranded tax effects from AOCI to retained earnings. This ASU is applicable only to tax effects relating to the Act, and the existing guidance regarding effects of other changes in tax laws is not affected. This ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018, with early adoption permitted in any interim period for which financial statements have not yet been issued. Adoption of this ASU is not expected to have a material effect on our financial position, results of operations and cash flows. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities. This ASU is intended to improve the financial reporting and presentation of hedging relationships and the economic results of risk management activities in financial statements. The amendments in ASU 2017-12 better align risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. In addition, the amendments permit hedge accounting for risk components involving non-financial and interest rate risks and contains other targeted improvements to simplify the application of hedge accounting. This ASU is effective for annual periods, and interim periods within those annual periods beginning after December 15, 2018, with early adoption permitted in any interim period following the issuance of this ASU. The provisions of this ASU should be applied to existing hedging relationships as of the beginning of the fiscal year of adoption. All other presentation and disclosure requirements are to be applied prospectively. We do not expect adoption of this ASU to have a material effect on our financial position, results of operations and cash flows. In February 2016, the FASB issued ASU No. 2016-02, Leases. This ASU requires the recognition of assets and liabilities for leases with lease terms of more than twelve months. The recognition, measurement and presentation of expenses and cash flows arising from a lease will depend primarily on its classification as a finance or an operating lease, with the classification criteria for distinguishing between the two being similar to the classification criteria for distinguishing between capital and operating leases under current GAAP. However, unlike current GAAP, recognition of finance and operating leases on the balance sheet is required, and additional disclosures are required to help financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. This ASU requires modified retrospective application for existing leases. This ASU will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, however, earlier application is permitted. The adoption of this ASU will have a material effect on our financial position, requiring us to recognize assets and liabilities for operating leases we have entered into for our principal executive offices as well as certain warehouse, manufacturing and distribution facilities globally. We have begun to evaluate and quantify the impact of our real estate leases, which represents the majority of our future minimum lease payments, and we will continue in our process of determining the full impact that recognition of right-of-use assets and liabilities will have on our financial position, results of operations and cash flows.
