Open in the 3D explorer

Dual classification applies to this structure.

G30.9† sequences before F00.9*
Dagger/asterisk pair: G30.9 (etiology, dagger) sequences before F00.9 (dementia in Alzheimer's disease, asterisk). The asterisk code cannot stand alone.

Neoplasm (2)

C71.9 Billable

Malignant neoplasm of brain, unspecified

Neoplasm of brain · SCTID 126952004

Coding advice: Special-group chapter II takes priority over the nervous-system chapter. Code the primary site; add C79.31 separately for a secondary (metastatic) brain lesion.

D33.2 Billable

Benign neoplasm of brain, unspecified

Neoplasm of brain · SCTID 126952004

Coding advice: Use when histology confirms a benign lesion.

Trauma (1)

S06.9X9A Billable

Unspecified intracranial injury with loss of consciousness of unspecified duration, initial encounter

Traumatic brain injury · SCTID 127295002

Coding advice: Chapter XIX is a special-group chapter and takes priority. An external cause code (V01-Y98) is mandatory as an additional code.

Degenerative / Other (3)

G30.9 † Billable

Alzheimer's disease, unspecified

Alzheimer's disease · SCTID 26929004

† Aetiology code - sequence before F00.9

Coding advice: Dagger/asterisk pair: G30.9 (etiology, dagger) sequences before F00.9 (dementia in Alzheimer's disease, asterisk). The asterisk code cannot stand alone.

I63.9 Billable

Cerebral infarction, unspecified

Cerebral infarction · SCTID 432504007

Coding advice: Assign residual neurological deficit codes separately; see the Neurological Deficits Following a Stroke standard.

I61.9 Billable

Nontraumatic intracerebral hemorrhage, unspecified

Cerebral infarction · SCTID 432504007

Coding advice: Hemorrhagic stroke - distinct from ischaemic infarction (I63.-).
