Decision pattern

The approval rate for Nathan Mellman has fluctuated over the 3,540 decisions on record since 2016. After a period of growth between 2016 and 2019, the trend showed variability before reaching a peak of 50% in 2024. The most recent data from 2026 shows an approval rate of 39% through the partial fiscal year, reflecting a shift from the higher rates seen in the previous two years. This recent period suggests a return toward the judge's historical average.

Preparing for an SSDI hearing

The guidance below applies to any SSDI hearing, not specifically to Judge Mellman'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.
