Approval rates
Comparing a judge's performance to broader benchmarks provides context for your upcoming hearing. While the national average approval rate sits at 58%, Judge Mucerino maintains a lifetime rate of 78% based on 20,324 decisions. In the most recent reporting period, her approval rate reached 89%, outpacing both the office average of 56% and the national average of 58%.
Office- and national-level breakdowns of fully favorable vs denial rates aren't currently published by SSA in the per-office disposition data. The judge's own breakdown is the detail we have today.
Approval rate over time
Year-over-year approval rate across Judge Mucerino'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
Over a decade on the bench, Judge Mucerino has demonstrated a consistent approach to disability adjudication. After a period of lower approval rates between 2018 and 2021, her decisions have trended upward, with 87% approval in 2024 and 90% in 2025. This recent shift reflects a period of high allowance frequency.
Preparing for an SSDI hearing
The guidance below applies to any SSDI hearing, not specifically to Judge Mucerino'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.

Other judges at this hearing office
The Social Security Administration uses a workload-balancing algorithm to assign cases, meaning the judge you are assigned is essentially random. Within the Phoenix Hearing Office, lifetime approval rates among the bench vary, ranging from 36% to 78%. Because case assignment is outside of your control, understanding the general environment of the office is more practical than focusing on individual peers.
