Year-over-year approval rate across Judge Mazzi's docket. Annual rates fluctuate with the mix of cases SSA assigns; the longer-run pattern is more informative than any single year.
Decision pattern
The approval trend for David R. Mazzi shows a shift over the 2,300 decisions on record since 2016. After a period of higher approval rates between 2016 and 2018, the data indicates a decline in the approval percentage through 2022. This pattern suggests that recent decisions have diverged from the earlier average. Such trends can be influenced by changes in the complexity of cases or the quality of medical evidence presented.
Preparing for an SSDI hearing
The guidance below applies to any SSDI hearing, not specifically to Judge Mazzi's bench. Judge-specific preparation guidance requires a corpus of public Appeals Council decisions involving each judge, which we haven't built yet.
- Bring a clean treating-physician record. Longitudinal primary-care or specialist notes spanning the disability period, with consistent symptom documentation, are typically the strongest evidence at hearing. A single month's records usually aren't enough.
- Don't rely on consultative exams alone. If your medical evidence is built primarily around a one-time CE finding, expect detailed questioning. Supplement with treating-source statements where possible.
- Prepare for daily-activity questions. Have honest, specific answers about a typical day. Answers that conflict with the medical record (in either direction) tend to hurt credibility.
- Expect transferable-skills probing. A vocational expert will usually testify about jobs available to someone with your limitations. Your representative should be prepared to cross-examine.
