Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These consolidated financial statements include the accounts of Misonix and its 100% owned subsidiaries. All significant intercompany balances and transactions have been eliminated. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all the information and footnotes required by U.S. GAAP for complete financial statements. As such, they should be read with reference to the Company’s Annual Report on Form 10-K for the year ended June 30, 2016, which provides a more complete explanation of the Company’s accounting policies, financial position, operating results, business properties and other matters. In the opinion of management, these financial statements reflect all adjustments considered necessary for a fair statement of interim results.
Reclassifications	Reclassifications Certain expenses on the Statement of Operations have been reclassified to be consistent with the current year presentation. Historically, the Company had recorded stock compensation expense and bonus expense predominantly within general and administrative expenses. The Company has reclassified the prior years’ presentation to allocate certain of these costs to cost of goods sold, selling expenses and research and development expenses, which is consistent with the classification being used in fiscal 2017. This reclassification had no impact on the Company’s presentation of operating income (loss) and the gross profit impact was not material.

These products are used for precise bone sculpting, removal of soft tumors, and tissue debridement in the fields of orthopedic surgery, plastic surgery, neurosurgery, podiatry and vascular surgery. In the United States, the Company sells its products through a network of commissioned agents assisted by Company personnel. Outside of the United States, the Company sells to distributors who then resell the product to hospitals. The Company operates as one business segment.
High Intensity Focused Ultrasound Technology	High Intensity Focused Ultrasound Technology The Company sold its rights to the high intensity focused ultrasound technology to SonaCare Medical, LLC (“SonaCare”) in May 2010. The Company may receive up to approximately $5.8 million in payment for the sale. SonaCare will pay the Company 7% of the gross revenues received from its sales of the (i) prostate product in Europe and (ii) kidney and liver products worldwide, until the Company has received payments of $3 million, and thereafter 5% of the gross revenues, up to an aggregate payment of $5.8 million, all subject to a minimum annual royalty of $250,000. Cumulative payments through December 31, 2016 were $1,254,788. No payments were received during the six months ended December 31, 2016. Payments are generally received once per year, in the Company’s third fiscal quarter.
Major Customers and Concentration of Credit Risk	Major Customers and Concentration of Credit Risk Included in sales from continuing operations are sales to Cicel (Beijing) Science and Tech Co. Ltd. (“Cicel”) of $0 and $899,635 for the six months ended December 31, 2016 and 2015, respectively. Accounts receivable from Cicel was $0 at December 31, 2016 and June 30, 2016. The Company terminated its agreement with Cicel in the first quarter of fiscal 2017. Total royalties from Medtronic Minimally Invasive Therapies (“MMIT”) related to their sales of the Company’s ultrasonic cutting products, which use high frequency sound waves to coagulate and divide tissue for both open and laparoscopic surgery, were $1,885,788 and $1,979,026, for the six months ended December 31, 2016 and 2015, respectively. Accounts receivable from MMIT royalties were approximately $1,885,788 and $973,000 at December 31, 2016 and June 30, 2016, respectively. The license agreement with MMIT expires in August 2017. At December 31, 2016 and June 30, 2016, the Company’s accounts receivable with customers outside the United States were approximately $341,000 and $768,000, respectively, none of which is over 90 days.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and judgments that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions are used for but not limited to establishing the allowance for doubtful accounts, valuation of inventory, depreciation, asset impairment evaluations and establishing deferred tax assets and related valuation allowances, and stock-based compensation. Actual results could differ from those estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In January 2017, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment. Under the new standard, goodwill impairment would be measured as the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying value of goodwill. This ASU eliminates existing guidance that requires an entity to determine goodwill impairment by calculating the implied fair value of goodwill by hypothetically assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. This update is effective for annual periods beginning after December 15, 2019, and interim periods within those periods. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company will apply this guidance to applicable impairment tests after the adoption date. In February 2016, the FASB issued guidance on lease accounting requiring lessees to recognize a right-of-use asset and a lease liability for long-term leases. The liability will be equal to the present value of lease payments. This guidance must be applied using a modified retrospective transition approach to all annual and interim periods presented and is effective for the Company beginning in fiscal 2019. The Company is currently in the early stages of evaluating this guidance to determine the impact it will have on its financial statements. In May 2014, the FASB issued guidance on revenue from contracts with customers. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include capitalization of certain contract costs, consideration of time value of money in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved, in certain circumstances. The guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity's contracts with customers. This guidance permits the use of either the retrospective or cumulative effect transition method and is effective for the Company beginning in 2019; early adoption is permitted beginning in 2018. The Company has not yet selected a transition method and is currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures. The FASB has also issued the following additional guidance clarifying certain issues on revenue from contracts with customers: Revenue from Contracts with Customers - Narrow-Scope Improvements and Practical Expedients and Revenue from Contracts with Customers - Identifying Performance Obligations and Licensing. The Company is currently in the early stages of evaluating this guidance to determine the impact it will have on its financial statements. There are no other recently issued accounting pronouncements that are expected to have a material effect on the Company's financial position, results of operations or cash flows.
