Question: Encounter notes indicate that a patient suffered from “dystonic CP.” I’m pretty sure this is a type of cerebral palsy, but I’m unsure of which diagnosis code to choose. Can you help? Massachusetts Subscriber Answer: The ICD-10 code you’re looking for is G80.3 (Athetoid cerebral palsy). “Dystonic cerebral palsy” is listed as an alternate term for athetoid CP. More on CP: There are several diagnosis codes in the G80.- (Cerebral palsy) code set. Here’s a list of the codes, along with information about alternate terms you might see when reporting these codes: o AKA: Congenital spastic paralysis (cerebral) o AKA: Spastic cerebral palsy NOS o AKA: Double athetosis (syndrome) o Dyskinetic cerebral palsy o Dystonic cerebral palsy o Vogt disease o AKA: Mixed cerebral palsy syndromes o AKA: Cerebral palsy NOS.
