42 U.S.C. § 1395ff(d)(1)(A), having to do with Medicare appeals:
Except as provided in subparagraph (B), an administrative law judge shall conduct and conclude a hearing on a decision of a qualified independent contractor under subsection (c) of this section and render a decision on such hearing by not later than the end of the 90-day period beginning on the date a request for hearing has been timely filed.You might ask why there is a time limit on Medicare appeals and no time limit on Social Security appeals, most of which linger for well over a year. The answer is simple. The Medicare appeals are filed by medical providers. They have political clout. Social Security claimants don't. In fairness, the medical providers have had trouble enforcing the section of statute I've quoted above but they're just gotten a decision indicating that the courts may be willing to enforce the time limit language.
