Listing 11.07 in 2026: Cerebral Palsy Adult SSDI Claims Under Paragraph A Disorganization of Motor Function in Two Extremities With Extreme Limitation, Paragraph B Marked Physical Plus Marked Mental Limitation, and Paragraph C Significant Interference in Communication From Speech, Hearing, or Visual Deficit

Cerebral palsy is one of the oldest listings in the Blue Book, and it's also one of the most misunderstood by adult claimants. Most people think of CP as a childhood diagnosis. It is, but the impairment lasts a lifetime and most adults with CP have never been evaluated for SSDI or SSI as adults. That's a real gap, because adults with even moderate CP often cannot sustain competitive employment past their mid-30s. Muscle tone changes, joint contractures build, post-impairment syndrome sets in, and the same body that got a person through school and early jobs runs out of margin.

This guide walks you through the verbatim text of Listing 11.07, what SSA means by disorganization of motor function and extreme limitation in the CP setting, how Paragraph B evaluates the combination of physical and mental limitations, when Paragraph C applies for communication deficits, how GMFCS levels and MACS classifications map into the SSA analysis, and how adult CP claims are often stronger than claimants realize when the file is built correctly. Two worked examples close the piece.

The Verbatim Text of Listing 11.07

SSA's Listing 11.07 in 2026 reads as follows under 20 CFR Part 404, Subpart P, Appendix 1:

You need any one of A, B, or C. Not all three. And the criteria differ meaningfully from Listing 11.12 or Listing 11.09 because CP is a lifelong static encephalopathy, not a progressive disease. That changes how SSA reads the record.

What SSA Means by Motor Disorganization in CP

Section 11.00D1 defines significant motor disorganization as an interference with movement of two extremities that results, despite prescribed treatment, in a sustained disturbance of gross and dexterous movements or gait and station. In cerebral palsy, this is what most adults are living with every day, though they may describe it in different terms.

The clinical shorthand used by physiatrists and neurologists breaks into a few common patterns. Spastic diplegia is bilateral leg spasticity, sometimes with mild arm involvement. Spastic hemiplegia is unilateral arm and leg spasticity, with the arm often more affected than the leg. Spastic quadriplegia involves all four limbs, usually with the arms more affected than the legs. Dyskinetic CP is uncontrolled movement, either athetoid, dystonic, or choreoathetoid patterns. Ataxic CP is coordination and balance loss. Mixed types combine two or more of these.

Any of these that involves two extremities and produces functional loss can meet the 11.00D1 threshold. Two extremities means any two, so a right arm plus right leg (hemiplegia) qualifies just as much as both legs (diplegia). It doesn't have to be the two most-affected limbs, just any two documented on exam.

Paragraph A: Extreme Limitation in Stand, Balance, or Upper Extremity Use

Section 11.00D2 defines extreme limitation. Extreme means an inability to stand up from a seated position without assistance, or an inability to maintain balance while standing or walking without an assistive device, or an inability to use the upper extremities to independently initiate, sustain, and complete work-related activities involving fine and gross movements.

SSA doesn't just want a diagnosis. It wants documented function. Your neurologist, physiatrist, PT, or OT needs to write specifically about one of the three sub-domains.

Extreme Limitation in Standing Up From Seated

Adult CP patients who cannot rise from a chair without pushing off with both arms, without a lift-assist device, or without help from another person meet this criterion. GMFCS Level IV and Level V adults typically fit this. Some Level III adults do as well, especially those with hip flexion contractures, hamstring shortening, or crouch gait.

Extreme Limitation in Balance While Standing or Walking

This is where the ataxic and mixed-type patients live. An adult who uses a walker or bilateral canes to walk household distances, who falls more than once a month, or who cannot stand at a work station without holding on with at least one hand, meets this criterion. Documentation from PT gait notes, fall diaries, and orthotist assessments carries this well.

Extreme Limitation in Upper Extremity Use

MACS (Manual Ability Classification System) Level III, IV, or V adults typically meet this. If you cannot open a jar, cannot handle fasteners, cannot sustain a pinch grip on a pen, cannot use a keyboard for typing at any productive speed, and cannot bring a cup to your mouth without spilling, that's an extreme limitation in fine and gross movements.

Under Paragraph A only one of these three sub-domains has to reach extreme. The other two can be moderate or even mild.

Paragraph B: Marked Physical Plus Marked Mental

Paragraph B pairs a physical marked limitation with a mental marked limitation. Both must be present. Marked is defined at 11.00G2 as more than moderate but less than extreme. Under 11.00G3a, marked physical limitation means a serious limitation in physical functioning, including the ability to independently initiate, sustain, and complete standing, balancing, walking, and using the upper extremities for work-related activities.

Physical marked limitation is easier to document than extreme, so many CP claimants who don't quite meet Paragraph A can still meet Paragraph B. Common pictures include GMFCS Level III adults who can walk with an assistive device but tire quickly, MACS Level II adults with slow and imprecise manipulation, and hemiplegic adults with weakness on the dominant side that limits vocational tasks.

The mental piece under 11.00G3b breaks into four areas, and you need marked limitation in only one. Adults with CP often show measurable limitation in more than one area because of the associated conditions that travel with CP.

Understanding, Remembering, or Applying Information

About 30 to 50 percent of adults with CP have an intellectual disability. Full-scale IQ below 70 supports marked limitation here. But you don't need a formal ID diagnosis. Adults with CP and processing speed deficits, learning disabilities, or executive function impairment can also show marked limitation in this area on formal neuropsychological testing.

Interacting With Others

Communication difficulties from dysarthria, isolation from years of physical dependence, and social anxiety are common in adult CP. If you have documented difficulty relating to supervisors, coworkers, or the public in typical work settings, that supports this area.

Concentrating, Persisting, or Maintaining Pace

ADHD and attention disorders co-occur with CP more often than in the general population. Slow processing speed, tone-related distractibility, and fatigue from the physical effort of ordinary tasks all contribute. Neuropsych testing that shows sustained attention below the fifth percentile is strong evidence.

Adapting or Managing Oneself

Emotional dysregulation, depression, and anxiety are diagnosable in over 25 percent of adults with CP. If you have documented mental health treatment for a mood or anxiety condition that limits work-related self-management, this area applies.

Paragraph C: Communication Deficit

Paragraph C is the shortest and most under-used path. It applies when there is significant interference in communication due to speech, hearing, or visual deficit.

Speech deficits from dysarthria are common in dyskinetic and spastic quadriplegic CP. If a listener cannot understand more than 60 percent of your connected speech, that's clinically significant. A speech-language pathologist can score intelligibility formally.

Hearing deficits are common in adults born prematurely with CP because of the shared risk factors of hyperbilirubinemia and hypoxia. Audiograms showing sensorineural loss of 40 dB or more at frequencies critical for speech understanding support Paragraph C. AAC (augmentative and alternative communication) device use is presumptive evidence of significant speech interference.

Visual deficits include cortical visual impairment, strabismus with severe amblyopia, and homonymous hemianopia from stroke-associated CP. If you can't read standard text without magnification even with corrective lenses, or if your visual field loss prevents safe navigation, Paragraph C applies.

GMFCS and MACS Mapping

SSA doesn't cite GMFCS or MACS in its listing, but adjudicators trained on pediatric-to-adult transitions read these classifications routinely.

The Adult CP Complication Nobody Tells You About

Post-impairment syndrome is real. Adults with CP experience accelerated musculoskeletal aging. By age 30, many patients have chronic pain, joint contractures that limit ROM below the pediatric baseline, and fatigue that shortens usable work hours. By age 40, ambulatory patients often lose ambulation and shift to wheeled mobility. Bone density drops earlier than the general population.

This progression matters for two reasons. First, the CP diagnosis stays static, but function declines, so re-evaluation for SSDI at ages 30 to 40 often produces a listing-level file when a pediatric-adult transition claim did not. Second, SSA can also reach a fair result via medical vocational grid rules if the listing isn't clearly met, especially for adults 50 and older.

Common Documentation That Wins Listing 11.07 Files

• Adult neurology or physiatry visit summarizing CP type, distribution, and GMFCS/MACS levels
• PT gait analysis with instrumented data or observational scales such as the Edinburgh Visual Gait Score
• OT assessment of upper extremity fine and gross function with specific work-related tasks tested
• Neuropsychological evaluation covering IQ, processing speed, attention, working memory, and mood inventory
• Speech-language evaluation with intelligibility scoring if speech is impaired
• Audiogram if hearing is impaired
• Formal visual field testing if there's cortical visual impairment or hemianopia
• Documentation of any use of AAC, wheelchair, walker, or ankle-foot orthoses
• Prior IEP or 504 records showing childhood functional limitations that persist

How Adult CP Interacts With SSI

Many adults with CP have never worked enough quarters to qualify for SSDI on their own record. That's where SSI and DAC (Disabled Adult Child) benefits come in.

DAC Benefits

If your parent worked and is now retired, disabled, or deceased, you can claim on the parent's record as a disabled adult child. Requirements are that your disability began before age 22 (CP always meets this) and that you have not married a non-disabled person, or have not engaged in SGA since age 22. DAC pays 50 percent of a retired parent's PIA or 75 percent of a deceased parent's PIA.

SSI

SSI is available regardless of work history if you meet financial thresholds. Federal SSI in 2026 pays up to $967 per month for an individual. Assets must stay under $2,000 for an individual. Many state supplements add small monthly amounts.

Worked Example: Priya, 34, Boston MA, Spastic Diplegia GMFCS III

Worked Example: Marcus, 42, Tampa FL, Spastic Quadriplegia GMFCS IV, MACS IV

The Common Rejections in Adult CP Cases

Assumption That Static Diagnosis Means Static Function

Adjudicators sometimes assume a childhood CP diagnosis means the same functional picture as pediatric records. Adult decline from post-impairment syndrome must be documented in the current record. Ask your adult physiatrist to compare current GMFCS to any recorded pediatric GMFCS and to state any functional decline explicitly.

Weak Upper Extremity Documentation

Adjudicators need specific work-related task descriptions. An OT note that says "grip strength 5 kg bilaterally, patient cannot open a water bottle, fasten shirt buttons, or sustain pinch on a pen beyond 10 seconds" beats a note that says "poor upper extremity function."

Missing Mental Health Documentation

Paragraph B needs the mental piece. If you have never been evaluated for the mental limitations that go with CP, ask your primary care to refer you to a neuropsychologist. Formal testing gives adjudicators the numbers they need.
