SSA listing text and criteria
Lumbar spinal stenosis resulting in compromise of the cauda equina (see 101.00G ), documented by A, B, C, and D:
Subsection A
Symptom(s) of neurological compromise manifested as: 1. Nonradicular distribution of pain in one or both lower extremities; or 2. Nonradicular distribution of sensory loss in one or both lower extremities; or 3. Neurogenic claudication. AND
- Nonradicular distribution of pain in one or both lower extremities; or
- Nonradicular distribution of sensory loss in one or both lower extremities; or
- Neurogenic claudication. AND
Subsection B
Nonradicular neurological signs present during physical examination (see 101.00C2 ) or on a diagnostic test (see 101.00C3 ) and evidenced by 1 and either 2 or 3: 1. Muscle weakness. 2. Sensory changes evidenced by: a. Decreased sensation; or b. Sensory nerve deficit (abnormal sensory nerve latency) on electrodiagnostic testing; or c. Areflexia, trophic ulceration, or bladder or bowel incontinence. 3. Decreased deep tendon reflexes in one or both lower extremities. AND
- Muscle weakness.
- Sensory changes evidenced by:
- Decreased deep tendon reflexes in one or both lower extremities. AND
Subsection C
Findings on imaging (see 101.00C3 ) or in an operative report (see 101.00C4 ) consistent with compromise of the cauda equina with lumbar spinal stenosis. AND
Subsection D
Impairment-related physical limitation of musculoskeletal functioning that has lasted, or is expected to last, for a continuous period of at least 12 months, and medical documentation of at least one of the following: 1. A documented medical need (see 101.00C6a ) for a walker, bilateral canes, or bilateral crutches (see 101.00C6d ) or a wheeled and seated mobility device involving the use of both hands (see 101.00C6e(i) ); or 2. An inability to use one upper extremity to independently initiate, sustain, and complete age-appropriate activities involving fine and gross movements (see 101.00E4 ), and a documented medical need (see 101.00C6a ) for a one-handed, hand-held assistive device (see 101.00C6d ) that requires the use of the other upper extremity or a wheeled and seated mobility device involving the use of one hand (see 101.00C6e(ii) ).
- A documented medical need (see 101.00C6a ) for a walker, bilateral canes, or bilateral crutches (see 101.00C6d ) or a wheeled and seated mobility device involving the use of both hands (see 101.00C6e(i) ); or
- An inability to use one upper extremity to independently initiate, sustain, and complete age-appropriate activities involving fine and gross movements (see 101.00E4 ), and a documented medical need (see 101.00C6a ) for a one-handed, hand-held assistive device (see 101.00C6d ) that requires the use of the other upper extremity or a wheeled and seated mobility device involving the use of one hand (see 101.00C6e(ii) ).

Where claims under 101.16 usually fail
A frequent miss is satisfying the symptom part (A) but not meeting the neurological signs structure in (B), which requires muscle weakness and documented sensory changes and/or decreased deep tendon reflexes in one or both lower extremities. Another failure mode is documentation that describes lumbar stenosis on imaging but does not show findings consistent with cauda equina compromise under (C). Some claims stop short on (D), which requires at least 12 months of impairment-related physical limitation and medical documentation of a specific mobility/assistive device need (walker, bilateral canes, bilateral crutches, or a wheeled and seated mobility device with the hands) or a specific one-upper-extremity limitation plus a one-handed assistive device need. Another pitfall is mixing up radicular patterns with the listing's focus on nonradicular distribution for pain and sensory loss in (A) and nonradicular neurological signs in (B).
Medical evidence that strengthens this claim
Evidence typically includes leg symptom descriptions matching subsection A (nonradicular distribution of pain or sensory loss in one or both lower extremities, or neurogenic claudication). Physical exam notes or diagnostic test results must support subsection B with nonradicular neurological signs: muscle weakness, sensory changes (decreased sensation, or a sensory nerve deficit with abnormal sensory nerve latency on electrodiagnostic testing, or areflexia/trophic ulceration/bladder or bowel incontinence), and decreased deep tendon reflexes in one or both lower extremities. Imaging reports or operative reports must include findings consistent with cauda equina compromise with lumbar spinal stenosis for subsection C. For subsection D, documentation must show the impairment-related physical limitation lasted or is expected to last at least 12 months, plus at least one of the listed medical-need items for assistive devices (walker, bilateral canes, bilateral crutches, or a wheeled and seated mobility device involving the use of both hands, or an inability to use one upper extremity for
What happens if your records do not meet this listing
This listing is built around four lettered parts (A, B, C, and D). If the claim does not match all of these, it generally moves to later steps where the overall level of functioning is assessed using residual functional capacity (RFC) and the child's ability to do age-appropriate activities. Many cases that fall short of a specific Blue Book listing still can be approved later based on the child's functional limits, but the decision depends on the total evidence about abilities and limitations over time, not only on whether imaging shows lumbar spinal stenosis.
Work activity and the SGA gate for this condition
For SSDI, the start of a claim uses the rules about whether work activity is being done at a level that would count as substantial. A condition under 101.16 includes long-lasting functional limits at least 12 months plus specific assistive device needs, which often align with difficulty sustaining age-appropriate activities, but approval still depends on the required medical documentation. If approved, eligibility continues based on the trial work period and the extended period of eligibility rules, which apply to people who meet the disability requirements.
