# SSDI denial reasons — the full list

Most denials are evidence-driven, not identity-driven — they can be reversed on appeal when the missing evidence is added.

**Direct answer:** The most common SSDI denial reasons are earnings above SGA, insufficient medical severity, missing or thin medical records, a condition not expected to last 12 months, failure to follow prescribed treatment, missed deadlines or forms, or a finding the claimant can still perform past or other work.

## Technical denials

Earnings above Substantial Gainful Activity, insufficient work credits, or missing forms and deadlines produce technical denials that are usually about paperwork, not medicine.

## Medical denials

Records that do not document severity, longitudinal treatment gaps, a condition not expected to last 12 months, or failure to follow prescribed treatment without good cause.

## Vocational denials

SSA finds a residual functional capacity that allows past work or, under the Grid Rules, other work given age, education, and skills.

## Why the appeal matters

Most winnable claims are lost at the initial level for evidence reasons — the record can be built and won at reconsideration or the ALJ hearing.
