SSA listing text and criteria
Systemic vasculitis , as described in 114.00D2 . With involvement of two or more organs/body systems, and with:
Subsection A
One of the organs/body systems involved to at least a moderate level of severity; AND
Subsection B
At least two of the constitutional symptoms and signs (severe fatigue, fever, malaise, or involuntary weight loss). Back to Top
Source: SSA Blue Book listing 114.03. Last synced 2026-05-04.
Where claims under 114.03 usually fail
A common failure is not meeting the 'two or more organs/body systems' requirement, because the listing is set up to cover multisystem involvement. Another failure is focusing on symptoms but missing the Subsection A threshold, where at least one organ/body system must be involved to at least a moderate level of severity. Another pitfall is counting only one constitutional symptom or sign when Subsection B requires at least two from the specified set (severe fatigue, fever, malaise, involuntary weight loss). A final pitfall is mixing up immune-system conditions that do not involve systemic vasculitis, since this listing is specifically for systemic vasculitis under the immune system disorders framework for children.
Medical evidence that strengthens this claim
Medical evidence needs to support both parts of the criteria: multisystem involvement (two or more organs/body systems) and constitutional symptoms/signs. For Subsection B, documentation should show at least two of these constitutional symptoms and signs: severe fatigue, fever, malaise, or involuntary weight loss. For Subsection A, the record needs support that at least one organ/body system is involved at a moderate level of severity. Because immune system disorders in children can affect multiple body systems and function, records that describe the extent of organ/body system involvement and track the constitutional symptoms over time are important for this listing.
What happens if your records do not meet this listing
If the exact criteria for 114.03 are not met, SSA still evaluates what the child can actually do in day to day life. Step 4 looks at the child's residual functional capacity (what activities are limited and why), using the medical evidence for the immune system disorder and its impact across organs/body systems. Step 5 applies the disability framework that determines whether the limitations are functionally equivalent to the listing level, even if the listing's exact lettered criteria are not all satisfied.
Work activity and the SGA gate for this condition
The listing criteria can involve constitutional symptoms such as severe fatigue, fever, malaise, or involuntary weight loss plus multisystem organ involvement, which often makes sustained functioning difficult. If the child is doing work-like activities above the substantial gainful activity level, SSA may still consider the claim not disabled under the earnings threshold rules used for child claims. If approved, eligibility continues under the usual rules for ongoing benefit eligibility after the initial period, following SSA's standard process for those awarded benefits for childhood disability claims. (No specific SGA amount is provided here.)
