Accounting Policies [Abstract] | |
Business and Basis of Presentation | Business and Basis of Presentation Our Business-An Overview NeuroMetrix, Inc. (the Company) is an innovation-driven company focused on the development and global commercialization of non-invasive medical devices for the diagnosis and treatment of pain and neurological disorders. Revenues are derived from the sale of medical devices and after-market consumable products and accessories. The Company’s products are cleared by the U.S. Food and Drug Administration (FDA) and regulators in foreign jurisdictions where appropriate. The Company has three commercial products. DPNCheck ® is a diagnostic device that provides rapid, point-of-care detection of peripheral neuropathies. ADVANCE ® is a diagnostic device that provides automated, in-office nerve conduction studies for the evaluation of focal neuropathies. Quell ® is a wearable neurostimulation device indicated for symptomatic relief of lower extremity chronic pain that is available over-the-counter. Unaudited Interim Financial Statements The accompanying unaudited balance sheet as of September 30, 2021, unaudited statements of operations, changes in stockholders' equity for the quarters and nine months ended September 30, 2021 and 2020 and cash flows for the nine months ended September 30, 2021 and 2020 have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. The accompanying balance sheet as of December 31, 2020 has been derived from audited financial statements prepared at that date but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of management, the financial statements include all normal and recurring adjustments considered necessary for a fair presentation of the Company’s financial position and operating results. Operating results for the nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021 or any other period. These financial statements and notes should be read in conjunction with the financial statements for the year ended December 31, 2020 included in the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission, or the SEC, on January 29, 2021 (File No. 001-33351). Revenues Revenues include product sales, net of estimated returns. Revenue is measured as the amount of consideration the Company expects to receive in exchange for product transferred. Revenue is recognized when contractual performance obligations have been satisfied and control of the product has been transferred to the customer. In most cases, the Company has a single product delivery performance obligation. Accrued product returns are estimated based on historical data and evaluation of current information. Accounts receivable are recorded at the amount the Company expects to collect, net of the allowance for doubtful accounts receivable. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses based on customer past payment history, product usage activity, and recent communications with the customer. Individual customer balances which are over 90 days past due are reviewed individually for collectability and written-off when recovery is not probable. Allowance for doubtful accounts was $25,000 as of September 30, 2021 and December 31, 2020. One customer accounted for 25% and 29% of total revenues in the quarter and nine months ended September 30, 2021, respectively. Three customers accounted for 47% and two customers accounted for 34% of total revenues in the quarter and nine months ended September 30, 2020, respectively. Two customers accounted for 50% of accounts receivable as of September 30, 2021 and December 31, 2020. Stock-based Compensation Total compensation cost related to non-vested awards not yet recognized at September 30, 2021 was $170,151. The total compensation costs are expected to be recognized over a weighted-average period of 1.3 years. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during reporting periods. Actual results could differ from those estimates. |

In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs utilize data points that are observable such as quoted prices, interest rates, and yield curves. Fair values determined by Level 3 inputs are unobservable data points for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. All Company assets and liabilities measured at fair value utilize Level 1 inputs.

Unaudited Interim Financial Statements | Unaudited Interim Financial Statements The accompanying unaudited balance sheet as of September 30, 2021, unaudited statements of operations, changes in stockholders' equity for the quarters and nine months ended September 30, 2021 and 2020 and cash flows for the nine months ended September 30, 2021 and 2020 have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. The accompanying balance sheet as of December 31, 2020 has been derived from audited financial statements prepared at that date but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of management, the financial statements include all normal and recurring adjustments considered necessary for a fair presentation of the Company’s financial position and operating results. Operating results for the nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021 or any other period. These financial statements and notes should be read in conjunction with the financial statements for the year ended December 31, 2020 included in the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission, or the SEC, on January 29, 2021 (File No. 001-33351). |
Revenues | Revenues Revenues include product sales, net of estimated returns. Revenue is measured as the amount of consideration the Company expects to receive in exchange for product transferred. Revenue is recognized when contractual performance obligations have been satisfied and control of the product has been transferred to the customer. In most cases, the Company has a single product delivery performance obligation. Accrued product returns are estimated based on historical data and evaluation of current information. Accounts receivable are recorded at the amount the Company expects to collect, net of the allowance for doubtful accounts receivable. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses based on customer past payment history, product usage activity, and recent communications with the customer. Individual customer balances which are over 90 days past due are reviewed individually for collectability and written-off when recovery is not probable. Allowance for doubtful accounts was $25,000 as of September 30, 2021 and December 31, 2020. One customer accounted for 25% and 29% of total revenues in the quarter and nine months ended September 30, 2021, respectively. Three customers accounted for 47% and two customers accounted for 34% of total revenues in the quarter and nine months ended September 30, 2020, respectively. Two customers accounted for 50% of accounts receivable as of September 30, 2021 and December 31, 2020. |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during reporting periods. Actual results could differ from those estimates. |
