G40.209 Localization-related (focal) (partial) symptomatic epilepsy and epileptic syndromes with complex partial seizures, not intractable, without status epilepticus

Localization-related (focal) (partial) symptomatic epilepsy epileptic syndromes with complex partial seizures NOS

345.41 Localization-related (focal) (partial) epilepsy and epileptic syndromes with complex partial seizures with intractable epilepsy
G40.211 Localization-related (focal) (partial) symptomatic epilepsy and epileptic syndromes with complex partial seizures, intractable, with status epilepticus

G40.219 Localization-related (focal) (partial) symptomatic epilepsy and epileptic syndromes with complex partial seizures, intractable, without status epilepticus
345.50 Localization-related (focal) (partial) epilepsy and epileptic syndromes with simple partial seizures, without mention of intractable epilepsy

G40.009 Localization-related (focal) (partial) symptomatic epilepsy and epileptic syndromes with seizures of localized onset, not intractable, without status epilepticus

Note that G40.001 and G40.009 are codes used for Benign childhood epilepsy with centrotemporal EEG spikes and Childhood epilepsy with occipital EEG paroxysms. These codes may not be used for adult-onset localization-related epilepsy

G40.011 Localization-related (focal) (partial) symptomatic epilepsy and epileptic syndromes with seizures of localized onset, intractable, with status epilepticus

G40.019 Localization-related (focal) (partial) symptomatic epilepsy and epileptic syndromes with seizures of localized onset, intractable, without status epilepticus

Note that G40.011 and G40.019 are codes used for Benign childhood epilepsy with centrotemporal EEG spikes and Childhood epilepsy with occipital EEG paroxysms. These codes may not be used for adult-onset localization-related epilepsy
(G40.1-, G40.2-)


G40.111 Localization-related (focal) (partial) symptomatic epilepsy and epileptic syndromes with simple partial seizures, intractable, with status epilepticus

G40.119 Localization-related (focal) (partial) symptomatic epilepsy and epileptic syndromes with simple partial seizures, intractable, without status epilepticus
