Basis of presentation [Abstract] |
Basis of Accounting, Policy [Policy Text Block] | The Company has prepared the Condensed Consolidated Financial Statements according to U.S. Generally Accepted Accounting Principles (GAAP) and has included the accounts of UnitedHealth Group and its subsidiaries. The year-end condensed consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by GAAP. In accordance with the rules and regulations of the U.S. Securities and Exchange Commission (SEC), the Company has omitted certain footnote disclosures that would substantially duplicate the disclosures contained in its annual audited Consolidated Financial Statements. Therefore, these Condensed Consolidated Financial Statements should be read together with the Consolidated Financial Statements and the Notes included in Part II, Item 8, “Financial Statements and Supplementary Data” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 as filed with the SEC (2022 10-K). The accompanying Condensed Consolidated Financial Statements include all normal recurring adjustments necessary to present the interim financial statements fairly.
Use of Estimates, Policy [Policy Text Block] | These Condensed Consolidated Financial Statements include certain amounts based on the Company’s best estimates and judgments. The Company’s most significant estimates relate to estimates and judgments for medical costs payable and goodwill. Certain of these estimates require the application of complex assumptions and judgments, often because they involve matters that are inherently uncertain and will likely change in subsequent periods. The impact of any change in estimates is included in earnings in the period in which the estimate is adjusted.
Revenue [Policy Text Block] | As of March 31, 2023 and December 31, 2022, accounts receivable related to products and services were $8.1 billion and $7.1 billion, respectively. Revenue expected to be recognized in any future year related to remaining performance obligations, excluding revenue pertaining to contracting having an original expected duration of one year or less, contracts where revenue recognized as invoiced and contracts with variable consideration related undelivered performance obligations, was $12.3 billion, of which approximately half is expected to be recognized in the next three years.
