Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)

DC 8512Neurological38 CFR 4.124a, DC 8512

An autoimmune condition where your immune system attacks the myelin sheath (protective coating) around your nerves, causing progressive weakness and numbness in your arms and legs. It is similar to Guillain-Barre but develops slowly over months instead of days.

How the VA rates this condition

The VA rates this condition based on how much it affects your ability to work and carry out daily activities. The examiner will focus on the functional limitations your condition causes, not just the diagnosis itself.

Diagnostic code

DC 8512

Rating range

20% – 80%

Rating levels

Rating criteria are defined in 38 CFR 4.124a, DC 8512. This guide presents a plain-language summary and is not a substitute for the full regulatory text. Always consult a VSO or VA-accredited attorney for case-specific advice.

Rating Levels

Severe incomplete paralysis — you have near-total loss of function in your hands or feet, you cannot walk without a wheelchair or walker, and you need help with daily tasks.

What the VA looks for

Near-total loss of grip or foot function
Wheelchair-dependent or bedridden
Severe muscle atrophy documented
Unable to perform most activities of daily living
Refractory to multiple treatment modalities

Common Pitfalls

⚠Not getting nerve conduction velocity (NCV) and electromyography (EMG) studies — these are essential for confirming the demyelinating pattern that distinguishes CIDP from other neuropathies and supports your diagnosis.
⚠Failing to document the progressive or relapsing nature of symptoms — CIDP is chronic by definition. Keep a symptom diary showing the waxing and waning pattern of weakness.
⚠Not filing for separate ratings for upper and lower extremities — CIDP typically affects all four limbs, and each extremity can be rated separately under the appropriate nerve code.
⚠Not documenting treatment requirements — if you need ongoing IVIG infusions, plasma exchange, or immunosuppressive medications, this shows the severity and chronic nature of your condition.
