been mentioned”). Here, the only form of representation “already described” in §406(b) is “represent[ation] before the court by an attorney.” Accordingly, the 25% cap applies only to fees for representation before the court, not the agency.
This interpretation is supported by “the structure of the statute and its other provisions.” Maracich v. Spears, 570 U. S. 48, 60 (2013). As an initial matter, subsections (a) and (b) address different stages of the representation. Section 406(a) addresses fees for representation “before the Commissioner,” whereas §406(b) addresses fees for representation in court. Because some claimants will prevail before the agency and have no need to bring a court action, it is unsurprising that the statute contemplates separate fees for each stage of representation.
These subsections also calculate fees differently. Section 406(b) applies a flat 25% cap on fees for court representation. By contrast, §406(a) provides two ways to determine fees for agency proceedings. Subsection (a)(2) caps fees based on a fee agreement at the lesser of 25% of past-due benefits or $6,000. Supra, at 2. If there is no fee agreement, the agency may set any fee, including a fee greater than 25% of past-due benefits, so long as the fee is “reasonable.” §406(a)(1).
Given this statutory structure, applying §406(b)’s 25% cap on court-stage fees to §406(a) agency-stage fees, or the aggregate of §§406(a) and (b) fees, would make little sense. Many claimants will never litigate in court, yet under the aggregate reading, agency fees would be capped at 25% based on a provision related exclusively to representation in court. Absent a fee agreement, §406(a)(1) subjects agency fees only to a reasonableness limitation, so applying §406(b)’s cap to such fees would add a limitation that Congress did not include in the relevant provision of the statute. If Congress had wanted these fees to be capped at 25%, it presumably would have said so directly in subsec-
