Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The unaudited consolidated financial statements include the accounts of the Company and its subsidiaries. Significant intercompany accounts and transactions have been eliminated in consolidation. The unaudited consolidated financial statements herein have been prepared by CorVel Corporation (“the Company”, “we”, “our”, “us”) pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The accompanying interim unaudited consolidated financial statements have been prepared under the presumption that users of the interim financial information have either read or have access to the audited consolidated financial statements for the latest fiscal year ended March 31, 2020. Accordingly, note disclosures which would substantially duplicate the disclosures contained in the March 31, 2020 audited consolidated financial statements have been omitted from these interim unaudited consolidated financial statements. The Company evaluated all subsequent events and transactions through the date of filing this report. Certain information and note disclosures normally included in financial statements prepared in accordance with United States generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. Operating results for the three and nine months ended December 31, 2020 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2021. For further information, refer to the audited consolidated financial statements and notes thereto for the fiscal year ended March 31, 2020 included in the Company's Annual Report on Form 10-K filed with the SEC on June 10, 2020.
Impact of COVID-19	Impact of COVID-19: The COVID-19 pandemic has impacted and could further impact our operations and the operations of our customers, suppliers and vendors as a result of quarantines, facility closures, illnesses, reduced medical services, and travel and logistics restrictions. The extent to which the COVID-19 pandemic impacts our business, results of operations, and financial condition will depend on future developments, which are highly uncertain and cannot be predicted. This includes, but is not limited to the duration, spread, severity, and impact of the COVID-19 pandemic, the effects of the COVID-19 pandemic on our customers, suppliers, and vendors, the remedial actions and stimulus measures adopted by federal, state, and local governments, the effects of stay at home mandates, the distribution and effectiveness of vaccines, and to what extent normal economic and operating conditions can resume. Even after the COVID-19 pandemic has subsided, we may continue to experience adverse impacts to our business as a result of any economic recession or depression that has occurred or may occur in the future. Therefore, the Company cannot reasonably estimate the full impact at this time.
Recent Accounting Pronouncements	Recent Accounting Pronouncements: In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes”. The pronouncement simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC Topic 740, “Income Taxes”. The pronouncement also improves consistent application of and simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance. This standard is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. We are still evaluating the impact this guidance will have on our consolidated financial statements. Guidance Adopted: In June 2016, the FASB issued ASU 2016-13 regarding ASC Topic 326, “Measurement of Credit Losses on Financial Instruments”. The pronouncement changes the impairment model for most financial assets and will require the use of an "expected loss" model for instruments measured at amortized cost. Under this model, entities will be required to estimate the lifetime expected credit loss on such instruments and record an allowance to offset the amortized cost basis of the financial asset, resulting in a net presentation of the amount expected to be collected on the financial asset. Subsequently, the FASB issued an amendment to clarify the implementation dates and items that fall within the scope of this pronouncement. This standard is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company has adopted this standard as of April 1, 2020. The adoption did not have a material impact on our consolidated financial statements. On an ongoing basis, the Company will contemplate forward-looking economic conditions in recording lifetime expected credit losses for the Company’s financial assets measured at cost. In January 2017, the FASB issued ASU 2017-04 regarding ASC Topic 350, “Simplifying the Test for Goodwill Impairment”. The pronouncement simplifies the accounting for goodwill impairments by eliminating step two from the goodwill impairment test. Under this guidance, if the carrying amount of a reporting unit exceeds its estimated fair value, an impairment charge shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. This standard is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. The Company has adopted this standard as of April 1, 2020. The adoption did not have a material impact on our consolidated financial statements.
