payments of past-due benefits–i. e., benefits that accrued before a favorable decision, 20 CFR §404.1703 (2018)–as well as ongoing monthly benefits, see 42 U. S. C. §423(a). A claimant who has been denied benefits “in whole or in part” by the Social Security Administration may seek administrative review of the initial agency determination, §405(b), and may then seek judicial review of the resulting final agency decision, §405(g).
As presently written, the Social Security Act “discretely” addresses attorney’s fees for the administrative and judicial-review stages: “§406(a) governs fees for representation in administrative proceedings; §406(b) controls fees for representation in court.” Gisbrecht v. Barnhart, 535 U. S. 789, 794 (2002). The original Social Security Act made no such provision for attorney’s fees in either proceeding. Id., at 793, n. 2. But in 1939, “Congress amended the Act to permit the Social Security Board to prescribe maximum fees attorneys could charge for representation of claimants before the agency.” Ibid. In 1965, Congress added a new subsection (b) to §406 that explicitly prescribed fees for representation before a court and “allow[ed] withholding of past-due benefits to pay” these fees directly to the attorney. Social Security Amendments of 1965, §332, 79 Stat. 403; Bowen, 485 U. S., at 76. In 1968, Congress amended subsection (a) to give the agency similar withholding authority to pay attorney’s fees incurred in administrative proceedings. Id., at 76.
Section 406(a) is titled “Recognition of representatives; fees for representation before Commissioner” of Social Security. It includes two ways to determine fees for representation before the agency, depending on whether a prior fee agreement exists. If the claimant has a fee agreement, subsection (a)(2) caps fees at the lesser of 25% of past-due benefits or a set dollar amount–currently $6,000. §406(a)(2)(A); Maximum Dollar Limit in the Fee Agreement Process, 74 Fed. Reg. 6080 (2009). Absent a fee
