Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1 — Summary of Significant Accounting Policies 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”) pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The accompanying interim unaudited 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, 2019. Accordingly, note disclosures which would substantially duplicate the disclosures contained in the March 31, 2019 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 months ended June 30, 2019 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2020. For further information, refer to the audited consolidated financial statements and notes thereto for the fiscal year ended March 31, 2019 included in the Company's Annual Report on Form 10-K filed with the SEC on June 7, 2019. Recent Accounting Pronouncements: 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. We are still evaluating the timing and impact this guidance will have on our consolidated financial statements. 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. We will evaluate the impact of this guidance on future annual or interim goodwill impairment tests performed. Guidance Adopted: In February 2016, the FASB issued ASU No. 2016-02, “Leases”, which sets out the principles for the recognition, measurement, presentation, and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for using an approach that is similar to the existing guidance for operating leases. The standard is to be applied using a modified retrospective transition method. The Company has adopted this standard as of April 1, 2019. The adoption of this standard did not have an impact on retained earnings on the consolidated balance sheet and is not expected to have a material impact on the consolidated statements of income. The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which allowed the Company to carry forward the historical assessments of whether contracts are or contain leases, lease classification and initial direct costs. The Company implemented internal controls and key system functionality to enable the preparation of financial information on adoption. Refer to Note 10 of the accompanying consolidated financial statements for a description of the impact of this adopted guidance.

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”) pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The accompanying interim unaudited 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, 2019. Accordingly, note disclosures which would substantially duplicate the disclosures contained in the March 31, 2019 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 months ended June 30, 2019 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2020. For further information, refer to the audited consolidated financial statements and notes thereto for the fiscal year ended March 31, 2019 included in the Company's Annual Report on Form 10-K filed with the SEC on June 7, 2019.
