Accounting Policies [Abstract]
Use of Estimates	The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and include amounts that are based on management’s best estimates and judgments. While all available information has been considered, actual amounts could differ from those estimates. These assumptions and estimates may change as new events occur and additional information is obtained, and such future changes may have an adverse impact on the Company's results of operations, financial position and liquidity.
Variable Interest Entity	The Company evaluates its ownership, contractual and other interests in entities to determine if it has any variable interest in a variable interest entity (“VIE”). These evaluations are complex and involve judgment and the use of estimates and assumptions based on available information. If the Company determines that an entity in which it holds a contractual or ownership interest is a VIE and that the Company is the primary beneficiary, such entity is consolidated in the Company’s consolidated financial statements. The primary beneficiary of a VIE is the party that meets both of the following criteria: (i) has the power to make decisions that most significantly affect the economic performance of the VIE; and (ii) has the obligation to absorb losses or the right to receive benefits that in either case could potentially be significant to the VIE. The Company performs ongoing reassessments of whether changes in the facts and circumstances regarding the Company’s involvement with a VIE will cause the consolidation conclusion to change. The Company operates certain clinical telehealth groups which are deemed to be Friendly-Physician Entities (“FPEs”) and due to legal requirements, the physician-owners must retain 100% of the equity interest. The Company’s agreements with FPEs generally consist of both an Administrative Service Agreement, which provides for various administrative and management services to be provided by the Company to the FPE, and Stock Transfer Restriction (“STR”) agreements with the physician-owners of the FPEs, which provide for the transition of ownership interest of the FPEs under certain conditions. The Company has the right to receive income as an ongoing management fee, which effectively absorbs all of the residual interests, and can also provide financial support through loans to the FPEs. The Company has exclusive responsibility for the provision of all nonmedical services including technology and intellectual property required for the day-to-day operation and management of each of the FPEs. In addition, the STR agreements provide that the Company has the right to designate a person(s) to purchase the equity interest of the FPE for a nominal amount in the event of a succession event at the Company’s discretion. Based on the provisions of these agreements, the Company determined that the FPEs are VIEs due to their equity holder having insufficient capital at risk, and the Company has a variable interest in the FPEs. The contractual arrangements described above allow Sequence to direct the activities that most significantly affect the economic performance of the FPEs. Accordingly, Sequence is the primary beneficiary of the FPEs and consolidates the FPEs under the VIE model. Furthermore, as a direct result of nominal initial equity contributions by the physicians, the financial support the Company can provide to the FPEs (e.g., loans) and the provisions of the contractual arrangements and nominee shareholder succession arrangements described above, the interests held by noncontrolling interest holders lack economic substance and do not provide them with the ability to participate in the residual profits or losses generated by the FPEs. Therefore, all income and expenses recognized by the FPEs are consolidated by the Company. The Company does not hold interests in any VIEs for which the Company is not deemed to be the primary beneficiary.
Revision of Previously Issued Consolidated Financial Statements	Revision of Previously Issued Consolidated Financial Statements After the three months ended September 30, 2023, the Company identified misstatements in its accounting for income taxes resulting primarily from the recording of a U.S. deferred tax liability related to a foreign branch of the U.S., partially offset by a U.S. deferred tax asset related to its U.S. leases, that should have been recorded in prior fiscal years. The Company evaluated the misstatements and concluded that the misstatements were not material, either individually or in aggregate, to its current or previously issued consolidated financial statements. To correct the immaterial misstatements, the Company has revised its previously issued consolidated financial statements as of and for the year ended December 31, 2022 and its unaudited consolidated financial statements for the nine months ended October 1, 2022. The revision of the historical consolidated financial statements also includes the correction of other immaterial misstatements that the Company had previously recorded as out-of-period adjustments. The Company had previously determined that these previously identified misstatements did not, either individually or in the aggregate, result in a material misstatement of its previously issued consolidated financial statements and reached the same conclusion when aggregating the previously identified misstatements with the recently identified misstatements. See Note 17 for further information regarding the misstatements and related revisions. The accompanying financial statements and relevant notes to the consolidated financial statements for the periods referenced above in this Quarterly Report on Form 10-Q have been revised to correct for such misstatements. Additionally, the Company will further present the revisions of its previously issued consolidated financial statements and relevant notes to the consolidated financial statements as of and for the year ended December 31, 2022 and prior in connection with the future filing of its 2023 Annual Report on Form 10-K.

The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and include amounts that are based on management’s best estimates and judgments. While all available information has been considered, actual amounts could differ from those estimates. These assumptions and estimates may change as new events occur and additional information is obtained, and such future changes may have an adverse impact on the Company's results of operations, financial position and liquidity.

Variable Interest Entity

The Company evaluates its ownership, contractual and other interests in entities to determine if it has any variable interest in a variable interest entity (“VIE”). These evaluations are complex and involve judgment and the use of estimates and assumptions based on available information. If the Company determines that an entity in which it holds a contractual or ownership interest is a VIE and that the Company is the primary beneficiary, such entity is consolidated in the Company’s consolidated financial statements. The primary beneficiary of a VIE is the party that meets both of the following criteria: (i) has the power to make decisions that most significantly affect the economic performance of the VIE; and (ii) has the obligation to absorb losses or the right to receive benefits that in either case could potentially be significant to the VIE. The Company performs ongoing reassessments of whether changes in the facts and circumstances regarding the Company’s involvement with a VIE will cause the consolidation conclusion to change.

The Company operates certain clinical telehealth groups which are deemed to be Friendly-Physician Entities (“FPEs”) and due to legal requirements, the physician-owners must retain 100% of the equity interest. The Company’s agreements with FPEs generally consist of both an Administrative Service Agreement, which provides for various administrative and management services to be provided by the Company to the FPE, and Stock Transfer Restriction (“STR”) agreements with the physician-owners of the FPEs, which provide for the transition of ownership interest of the FPEs under certain conditions. The Company has the right to receive income as an ongoing management fee, which effectively absorbs all of the residual interests, and can also provide financial support through loans to the FPEs. The Company has exclusive responsibility for the provision of all nonmedical services including technology and intellectual property required for the day-to-day operation and management of each of the FPEs. In addition, the STR agreements provide that the Company has the right to designate a person(s) to purchase the equity interest of the FPE for a nominal amount in the event of a succession event at the Company’s discretion. Based on the provisions of these agreements, the Company determined that the FPEs are VIEs due to their equity holder having insufficient capital at risk, and the Company has a variable interest in the FPEs.

The contractual arrangements described above allow Sequence to direct the activities that most significantly affect the economic performance of the FPEs. Accordingly, Sequence is the primary beneficiary of the FPEs and consolidates the FPEs under the VIE model. Furthermore, as a direct result of nominal initial equity contributions by the physicians, the financial support the Company can provide to the FPEs (e.g., loans) and the provisions of the contractual arrangements and nominee shareholder succession arrangements described above, the interests held by noncontrolling interest holders lack economic substance and do not provide them with the ability to participate in the residual profits or losses generated by the FPEs. Therefore, all income and expenses recognized by the FPEs are consolidated by the Company. The Company does not hold interests in any VIEs for which the Company is not deemed to be the primary beneficiary.

Revision of Previously Issued Consolidated Financial Statements

After the three months ended September 30, 2023, the Company identified misstatements in its accounting for income taxes resulting primarily from the recording of a U.S. deferred tax liability related to a foreign branch of the U.S., partially offset by a U.S. deferred tax asset related to its U.S. leases, that should have been recorded in prior fiscal years. The Company evaluated the misstatements and concluded that the misstatements were not material, either individually or in aggregate, to its current or previously issued consolidated financial statements.

To correct the immaterial misstatements, the Company has revised its previously issued consolidated financial statements as of and for the year ended December 31, 2022 and its unaudited consolidated financial statements for the nine months ended October 1, 2022. The revision of the historical consolidated financial statements also includes the correction of other immaterial misstatements that the Company had previously recorded as out-of-period adjustments. The Company had previously determined that these previously identified misstatements did not, either individually or in the aggregate, result in a material misstatement of its previously issued consolidated financial statements and reached the same conclusion when aggregating the previously identified misstatements with the recently identified misstatements. See Note 17 for further information regarding the misstatements and related revisions.

The accompanying financial statements and relevant notes to the consolidated financial statements for the periods referenced above in this Quarterly Report on Form 10-Q have been revised to correct for such misstatements. Additionally, the Company will further present the revisions of its previously issued consolidated financial statements and relevant notes to the consolidated financial statements as of and for the year ended December 31, 2022 and prior in connection with the future filing of its 2023 Annual Report on Form 10-K.
