Diagnostic Code 8107 · 38 CFR §4.124a
Athetosis is a movement disorder characterized by slow, continuous, writhing involuntary movements, most commonly affecting the hands and feet, sometimes extending to the face and trunk. Acquired athetosis (the form DC 8107 captures) develops in adulthood as a residual of brain injury — specifically damage to the basal ganglia from anoxic-ischemic injury (after cardiac arrest, near-drowning, severe blood loss), traumatic brain injury, stroke, encephalitis, or drug exposure (certain antipsychotic medications, kernicterus historically). It is distinct from congenital athetosis of cerebral palsy, which is present from birth. For veterans, the relevant pathways for service connection are direct nexus to a service-related head injury, anoxic event, stroke, or encephalitis. Treatment uses dopamine receptor modulators, GABA-ergic medications, and sometimes deep brain stimulation in severe cases. The VA rates DC 8107 based on the severity and distribution of the athetoid movements and their functional impact.
| Rating | Criteria |
|---|---|
| 10% | Mild acquired athetosis — slight athetoid movements limited to one body part (typically a hand), partial response to medication, minor functional limitation. |
| 30% | Moderate acquired athetosis — athetoid movements affecting multiple body parts, definite functional limitation in fine motor tasks (writing, buttoning, eating), partial response to medication. |
| 60% | Severe acquired athetosis — pronounced athetoid movements affecting multiple body parts including extremities and face, substantial functional limitation in activities of daily living, refractory to medication. |
| 100% | Total impairment — generalized athetoid movements producing total functional disability, inability to perform activities of daily living independently, requirement for aid and attendance. Special Monthly Compensation under 38 USC 1114 applies based on the specific functional losses (loss of use of limbs, aid and attendance). |
A neurology diagnosis distinguishing acquired athetosis from other movement disorders (chorea, dystonia, ballism, tics) and from congenital athetosis is the anchor. Brain imaging (MRI) showing basal ganglia damage from the original insult supports the diagnosis. Documentation of the underlying cause — anoxic-ischemic event, TBI, stroke, encephalitis, drug exposure — establishes the nexus. Video documentation captures the movements. Treatment records covering medications and any interventional procedures (deep brain stimulation) demonstrate the management burden. Service medical records establishing the in-service triggering event close the nexus.
Cerebral palsy is a congenital condition present from birth, typically caused by perinatal brain injury, and it is not usually relevant to veteran claims unless the veteran had a service-aggravation of premorbid disease. Acquired athetosis (DC 8107) develops in adulthood as a residual of an identifiable brain injury — traumatic, anoxic, infectious, or drug-induced. The rating framework, the underlying pathology, and the legal pathways for service connection differ entirely.
Possibly, through the medication-side-effect pathway. If antipsychotic medication was prescribed by VA providers for a service-connected mental health condition and produced tardive athetosis or tardive dyskinesia as a side effect, the movement disorder is generally service-connectable as secondary to the underlying mental health condition (because the medication was used to treat the service-connected disease). DC 8103 (tardive dyskinesia) often applies more directly than DC 8107 for medication-induced movement disorders, so request evaluation under both.
When athetosis bilateral upper extremities is severe enough that the veteran cannot reliably use the hands for activities of daily living — eating, dressing, hygiene, writing — the functional loss can support an SMC evaluation under 38 USC 1114(k) for loss of use of a creative organ or upper extremity, or higher SMC tiers when the functional impact extends to multiple body areas or warrants aid and attendance. The SMC framework is technical and the specific tier depends on the precise functional losses; a representative or attorney experienced with SMC claims can match the picture to the right tier.
