SSDI vs Private Disability: Approval rates
Approval rates: SSDI — ~35–40% initial; private — per contract terms.

| Aspect | Approval rates |
|---|---|
| SSDI | ~35–40% initial |
| Private policy | Per contract terms |
SSDI denies roughly two-thirds of initial applications; private claims approve at much higher rates because the contract definition, not a federal standard, governs. Both can be true at once — the standards differ.

SSDI and private coverage are not substitutes — most long-term claimants end up with both, coordinated through offset provisions.
The coordination trap
Claimants who file private first and SSDI second often trigger overpayment recovery: the private carrier paid full benefits assuming no SSDI, then claws back the offset portion retroactively. File both claims and report each to the other.
Which one to prioritize
SSDI’s process is slow and approval is a federal-standard fight; private claims move on contract language. File private immediately at elimination-period start, SSDI as soon as the 5-month wait is in sight, and let a disability attorney sequence the overlap.
On approval rates, the systems differ enough that sequencing matters more than effort.
