Organization, Consolidation and Presentation of Financial Statements [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Consolidated Financial Statements The accompanying consolidated financial statements include the accounts of Apyx, its wholly owned subsidiary, Apyx Bulgaria, EOOD, and its 51% owned subsidiary, Apyx SY Medical Devices (Ningbo) Co., Ltd. (collectively, "Apyx," or the “Company”). All significant intercompany transactions and balances have been eliminated in consolidation. Use of Estimates in the Preparation of Financial Statements The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. The reported amounts of revenues and expenses during the reporting period may be affected by the estimates and assumptions the Company is required to make. Cash and Cash Equivalents Holdings of highly liquid investments with original maturities of three months or less from the date of purchase are considered to be cash equivalents. As of December 31, 2021 and 2020, all of the Company’s investments are in money market funds or in Treasury Bills with original maturities of three months or less and are included in cash and cash equivalents. Concentration of Credit Risk Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist primarily of trade accounts receivable. With respect to cash, the Company frequently maintains cash and cash equivalent balances in excess of federally insured limits; it has not experienced any losses in such accounts. Trade Accounts Receivable and Allowance for Doubtful Accounts The Company's standard credit terms for billings range from net 30 days to net 120 days, depending on the customer agreement. Accounts receivable are determined to be past due if payments are not made in accordance with such agreements and an allowance is generally recorded for accounts that become three months past due, or sooner if there are other indicators that the receivables may not be recovered. Customary collection efforts are initiated, and receivables are written off when the Company determines they are not collectible and abandons these collection efforts. The Company evaluates the allowance for doubtful accounts on a regular basis for adequacy based upon its periodic review of the collectability of the receivables in light of historical experience, adverse situations that may affect its customers’ ability to pay and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available. Management believes that the allowances for doubtful accounts of approximately $0.4 million and $0.3 million at December 31, 2021 and 2020, respectively, are adequate to provide for probable bad debts. Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined on a first in, first out basis. Finished goods and work-in-process inventories include material, labor and overhead costs. Factory overhead costs are allocated to manufactured inventory based upon labor hours. The Company monitors inventory usage to determine if the carrying value of any items should be adjusted due to lack of demand for the item and adjusts inventory for estimated obsolescence or unusable inventory equal to the difference between the cost of inventory and the estimated net realizable value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required. Property and Equipment Property and equipment are recorded at cost. Depreciation and amortization are provided for using the straight-line method over the estimated useful lives of the assets. The amortization of leasehold improvements is based on the shorter of the lease term or the life of the improvement. Betterments and major improvements, which extend the life of the asset, are capitalized, whereas maintenance and repairs and routine improvements are expensed as incurred. The estimated useful lives are: buildings and improvements, 39 years; machinery and equipment, 3-10 years; furniture and fixtures, 5-10 years; computer equipment and software, 3-5 years; and molds, 7-15 years. Valuation of Long-Lived Assets The Company reviews long-lived assets for recoverability if events or changes in circumstances indicate that the assets may have been impaired. This circumstance exists when the carrying amount of the asset exceeds the sum of the undiscounted cash flows expected to result from its use and eventual disposition. In those cases, an impairment loss is recognized to the extent that the assets’ carrying amount exceeds its fair value. Any impairment losses are not restored in the future if the fair value increases. At December 31, 2021 and 2020, the Company believes the remaining carrying values of its long-lived assets are recoverable. Product Warranties The Company provides a four year limited warranty on end-user sales of its Renuvion®/J-Plasma® generators, a two year warranty on mounting fixtures, and a one-year warranty on certain accessories. The Company estimates and provides for future costs for product warranties in cost of sales at the time revenue is recognized. The Company bases its product warranty costs on related material costs, repair labor costs and shipping costs. The Company estimates the future cost of product warranties by considering historical material, repair labor, and shipping costs, and applying the experience rates to the outstanding warranty period for products sold. It is reasonably possible that actual results could differ from those estimates. Revenue Recognition Revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration that the Company expects to receive for those goods or services. To recognize revenue, the Company (i) identifies the contract(s) with a customer; (ii) identifies the performance obligations in the contract; (iii) determines the transaction price; (iv) allocates the transaction price to the performance obligations in the contract; and (v) recognizes revenue when, or as, it satisfies the performance obligation(s). For sales of the Company's Advanced Energy products (Renuvion®/J-Plasma®), this is at a point in time when title has been transferred to the customer, which is generally at the time of shipment or receipt by customer for FOB destination terms. For sales of products under its OEM agreements, the Company recognizes revenue over time when no alternative use exists for the manufactured goods and the Company has rights to payment. Presently, the Company does not stock any significant completed goods under its OEM agreements, accordingly, the recognition of revenue under these agreements approximates point in time recognition. The following policies apply to its major categories of revenue transactions: •The majority of sales to customers are evidenced by firm purchase orders. Generally, title and the risks and rewards of ownership are transferred to the customer when the product is shipped. Payment by the customer is due under fixed payment terms. •Product returns are only accepted at the Company's discretion and in accordance with its “Returned Goods Policy”. Historically, the level of product returns has not been significant. Accruals for sales returns, rebates and allowances are made as a reduction of revenue based upon an analysis of historical customer returns and credits, rebates, discounts and current market conditions. •The terms of sale to customers generally do not include any obligations to perform future services. Limited warranties are generally provided for sales and provisions for warranty are provided at the time of product sale based upon an analysis of historical data. •In connection with the execution of OEM supply agreements, the Company may enter into an accompanying product development agreement. If the Company enters into a product development agreement, and development of the goods does not represent a performance obligation on a standalone basis, the Company defers the development fees billed to customers and the associated costs. Recognition of the deferred billings and costs will occur as the Company performs on the accompanying supply arrangements. Advertising Costs Advertising costs are expensed as incurred. The amounts of advertising costs, including trade shows, were approximately $1.3 million and $0.8 million for the years ended December 31, 2021 and 2020, respectively. Stock-Based Compensation The Company accounts for stock-based compensation in accordance with FASB ASC Topic 718, Compensation-Stock Compensation. FASB ASC 718 requires recognizing compensation expense for all share-based payment awards made to employees, directors and non-employees based upon the grant date fair value of such awards. It accounts for forfeitures as they occur. The standard covers employee stock options, restricted stock and other equity awards. The Company utilizes a Black-Scholes model to estimate the grant date fair value of stock option awards. For employee and director awards, compensation expense is recognized on a straight-line basis over the vesting periods. For non-employee awards, compensation expense is recorded for non-forfeitable, fully vested awards at the grant date. For other awards granted to non-employees, compensation cost is recognized as services are provided, which approximates a straight-line basis over the vesting period. Litigation Contingencies In accordance with authoritative guidance, the Company accrues a liability in its consolidated financial statements for these actions when a loss is known or considered probable and the amount can be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. If a loss is reasonably possible, but not known or probable, and can be reasonably estimated, the estimated loss or range of loss is disclosed in the notes to the consolidated financial statements. In most cases, significant judgment is required to estimate the amount and timing of a loss to be recorded; actual results may differ from those estimates. Earnings (Loss) Per Share The Company computes basic (loss) earnings attributable to common stockholders per share by dividing net (loss) income attributable to common stockholders by the weighted average number of common shares outstanding for the reporting period. Diluted (loss) earnings per share attributable to common stockholders gives effect to all potential dilutive shares outstanding during the period. The number of dilutive shares is calculated using the treasury stock method which reduces the effective number of shares by the amount of shares the Company could purchase with the proceeds of assumed exercises. Anti-dilutive units are excluded from the calculation of diluted shares. In periods of loss, all potentially dilutive units are anti-dilutive and are excluded from the calculation of diluted income (loss) per share. Research and Development Costs Research and development expenses are charged to operations as incurred. Income Taxes The Company utilizes the liability method of accounting for income taxes as set forth in FASB ASC Topic 740, Income Taxes. Under the liability method, deferred taxes are determined based on temporary differences between the financial statement and tax bases of assets and liabilities using tax rates expected to be in effect during the years in which the deferred taxes reverse. The Company accounts for interest and penalties on income taxes as income tax expense. A valuation allowances is recorded when it is more likely than not that a tax benefit will not be realized. In determining the need for valuation allowances the Company considers projected future taxable income, the timing of reversals of temporary differences, and the availability of tax planning strategies. As of December 31, 2021 and 2020, the Company recorded a valuation allowance on the net deferred tax assets. The Company assesses the realizability of deferred tax assets each reporting period and will be able to reduce the valuation allowance to the extent the financial results of continuing operations improve, and it becomes more likely than not that the deferred tax assets will be realized. As Management has not fully determined the timing of when it will generate taxable income in the U.S., the Company will continue to record a full valuation allowance on the net deferred tax assets as of December 31, 2021. As a result of the CARES Act, during 2020, the Company released the valuation allowance on the Federal NOLs 2019 and 2020 that have been carried back to prior taxable years. The Company assesses the financial statement impact of an uncertain tax position taken or expected to be taken on an income tax return at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized in the financial statements unless it is more likely than not of being sustained. Foreign Currency Transactions The functional currency of Apyx Bulgaria is the U.S. dollar. The monetary assets and liabilities that are denominated in a currency other than U.S. dollar are remeasured into U.S. dollars at the exchange rate on the balance sheet date, while nonmonetary items are remeasured at historical rates. Revenue and expenses are remeasured at weighted average exchange rates during the period. Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in selling, general and administrative expenses in the Consolidated Statements of Operations and were not material for the years ended December 31, 2021 and 2020. RECENT ACCOUNTING PRONOUNCEMENTS In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326). The update changes the impairment model for most financial assets and certain other instruments, including trade and other receivables, contract assets, held-to-maturity debt securities and loans, and requires entities to use a new forward-looking expected loss model that will result in the earlier recognition of allowance for losses. This update, as originally issued, was effective for annual and interim periods beginning after December 15, 2019, with early adoption permitted. In November 2019, the FASB issued ASU 2019-10, Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) Effective Dates, which deferred the effective dates of these standards for Smaller Reporting Companies until fiscal years beginning after December 15, 2022. The Company currently expects to continue to qualify as a Smaller Reporting Company, based upon the current SEC definition and, as a result, will be utilizing the deferred elective date. While the Company is in the process of determining the effects of the adoption of the standard on the consolidated financial statements, it does not expect the impact to be material. No other new accounting pronouncement issued or effective during the fiscal year had or is expected to have a material impact on the Company's consolidated financial statements or disclosures.

The accompanying consolidated financial statements include the accounts of Apyx, its wholly owned subsidiary, Apyx Bulgaria, EOOD, and its 51% owned subsidiary, Apyx SY Medical Devices (Ningbo) Co., Ltd. (collectively, "Apyx," or the “Company”). All significant intercompany transactions and balances have been eliminated in consolidation.
