Open stage 05
Most Colorado claimants are denied at stages 1 and 2. The decision that actually matters is the ALJ hearing — and that’s where careful preparation makes the biggest difference. Total timeline from filing to an ALJ decision in 2026: typically 18 to 28 months.
Most cases are won at the hearing.
National data: only about 35% of initial applications are approved. The number that matters is the ALJ approval rate — 62.4% at Denver OHO in 2025. Prepare for the hearing; the earlier stages are mostly procedural.
Documentation wins or loses everything.
The single biggest variable in your outcome is the quality of your medical record at the time of the hearing. A treating physician’s functional capacity statement is often the most decisive piece of evidence in the file.
The vocational expert is cross-examined.
Every ALJ hearing includes vocational expert testimony about jobs you can supposedly still perform. The cross-examination of that expert is where many cases turn — demonstrating that the cited jobs don’t fit your actual residual functional capacity.
