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, 2018. Accordingly, note disclosures which would substantially duplicate the disclosures contained in the March 31, 2018 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. During the period subsequent to the quarter ended June 30, 2018, the Company repurchased 24,001 shares of common stock for $1,334,000 at an average of $55.60 per share of common stock. These shares of common stock were repurchased under the Company’s share repurchase program described in Note 4. 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, 2018 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2019. For further information, refer to the audited consolidated financial statements and notes for the fiscal year ended March 31, 2018 included in the Company's Annual Report on Form 10-K filed with the SEC on June 8, 2018. Recent Accounting Pronouncements: 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 effective April 1, 2019, with early adoption permitted. The standard is to be applied using a modified retrospective transition method. The Company is currently evaluating the impact of adoption on its consolidated financial position, results of operations, and cash flows. Guidance Adopted: On May 28, 2014, the FASB issued ASU 2014-09 regarding ASC Topic 606, “Revenue from Contracts with Customers”. This standard provides principles for recognizing revenue for the transfer of promised goods or services to customers with the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB approved a one-year delay of the effective date of this new revenue recognition standard. The guidance will now be effective for the Company’s fiscal year beginning April 1, 2018. The Company has adopted this standard as of April 1, 2018. Refer to Note 2 of the accompanying consolidated financial statements for a description of the impact of the adopted guidance. In January 2016, the FASB issued ASU 2016-01 regarding Subtopic 825-10, “Financials Instruments — Overall: Recognition and Measurements of Financial Assets and Financial Liabilities”. The standard addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. It requires that most equity investments be measured at fair value, with subsequent changes in fair value recognized in net income. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company adopted this guidance prospectively on April 1, 2018. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows”, which reduces diversity in the practice of how certain transactions are classified in the statement of cash flows. The new guidance is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted. The Company adopted this guidance prospectively on April 1, 2018. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.
