Epilepsy and recurrent seizures - G40

G40 Category in ICD-10-CM facilitate the systematic organization of medical information for accurate and standardized healthcare practices.

Category Notes:

the following terms are to be considered equivalent to intractable: pharmacoresistant (pharmacologically resistant), treatment resistant, refractory (medically) and poorly controlled

Excludes1: It indicates that the conditions described by two codes cannot occur together in the same patient. These codes are mutually exclusive.

Type 1 Excludes:

conversion disorder with seizures (F44.5)
convulsions NOS (R56.9)
post traumatic seizures (R56.1)
seizure (convulsive) NOS (R56.9)
seizure of newborn (P90)

Excludes2: This note means that the conditions described by two codes are not usually associated with each other but can sometimes occur together.

Type 2 Excludes:

hippocampal sclerosis (G93.81)
mesial temporal sclerosis (G93.81)
temporal sclerosis (G93.81)
Todd's paralysis (G83.84)

These ranges represents subcategories of Epilepsy and recurrent seizures. The "G40" signifies that these are the diseases within this broad category.
