SSA listing text and criteria
Systemic vasculitis . As described in 14.00D2 . With:
Subsection A
Involvement of two or more organs/body systems, with: 1. One of the organs/body systems involved to at least a moderate level of severity; and 2. At least two of the constitutional symptoms or signs (severe fatigue, fever, malaise, or involuntary weight loss). OR
- One of the organs/body systems involved to at least a moderate level of severity; and
- At least two of the constitutional symptoms or signs (severe fatigue, fever, malaise, or involuntary weight loss). OR
Subsection B
Repeated manifestations of systemic vasculitis, with at least two of the constitutional symptoms or signs (severe fatigue, fever, malaise, or involuntary weight loss) and one of the following at the marked level: 1. Limitation of activities of daily living. 2. Limitation in maintaining social functioning. 3. Limitation in completing tasks in a timely manner due to deficiencies in concentration, persistence, or pace. Back to Top

Where claims under 14.03 usually fail
A frequent failure mode is meeting only one constitutional symptom or signing up only one symptom instead of the required two (severe fatigue, fever, malaise, or involuntary weight loss). Another pitfall is describing multi-organ involvement without showing that at least one organ or body system is involved to at least a moderate level of severity. Some claims get stuck when the disease effects are real but not framed in the specific marked functional areas listed for subsection B (activities of daily living, social functioning, or timely task completion due to deficiencies in concentration, persistence, or pace). Others miss because they focus on one body system only, even though subsection A requires involvement of two or more organs or body systems.
Medical evidence that strengthens this claim
Documentation needs to line up with the specific lettered criteria. Evidence should identify systemic vasculitis as affecting two or more organs or body systems, and it should describe severity at least as 'moderate' for one of those organ or body systems (subsection A). Medical records should document constitutional symptoms or signs, and the record should clearly show at least two of: severe fatigue, fever, malaise, or involuntary weight loss. For subsection B, documentation should support repeated manifestations of systemic vasculitis, and it should also include the required constitutional symptoms plus marked limitations in one of the listed functional areas (activities of daily living, maintaining social functioning, or timely completion of tasks due to deficiencies in concentration, persistence, or pace).
What happens if your records do not meet this listing
If section A or section B is not met exactly, the process generally moves to steps that look at what functional limits remain for work. SSA considers residual functional capacity, meaning what an individual can still do despite symptoms and medical restrictions. Even when a specific Blue Book listing is not met, the medical evidence can still support limitations, which can then affect whether work is realistically possible. For people who qualify based on functional limits rather than a specific listing match, the overall picture of day-to-day functioning becomes especially important.
Work activity and the SGA gate for this condition
For SSDI, work activity after onset is considered under the substantial gainful activity (SGA) gate, so working at SGA levels can prevent eligibility even if symptoms are severe. With systemic vasculitis under 14.03, the criteria focus on constitutional symptoms like severe fatigue, fever, malaise, or involuntary weight loss and the associated multi-system or marked functional limitations (for example, marked limitation in activities of daily living under subsection B). If approved, trial work period and extended period of eligibility rules apply like they do for other disabilities, so the ability to work can change over time after approval. The listing itself does not set any SGA dollar figure, but the SGA rule still governs whether ongoing work prevents benefits at the start of the SSDI claim.
