ICD-10-CM Code I68.0
Cerebral amyloid angiopathy
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.Manifestation Code
Certain ICD-10-CM codes identify an underlying condition known as an etiology code. Conditions that arise as a result of an underlying condition (etiology), are referred to as Manifestations. In ICD-10-CM, etiology codes must be coded first, followed by the manifestation codes. When a condition requires etiology and manifestation codes, there is a "use additional code" note following the etiology code and a "code first" note following the manifestation code.I68.0 is a billable ICD code used to specify a diagnosis of cerebral amyloid angiopathy. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code I680 is used to code Cerebral amyloid angiopathy
Cerebral amyloid angiopathy (CAA), also known as congophilic angiopathy, is a form of angiopathy in which amyloid deposits form in the walls of the blood vessels of the central nervous system. The term congophilic is used because the presence of the abnormal aggregations of amyloid can be demonstrated by microscopic examination of brain tissue after application of a special stain called Congo red. The amyloid material is only found in the brain and as such the disease is not related to other forms of amyloidosis.

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)
This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code I68.0 and a single ICD9 code, 437.8 is an approximate match for comparison and conversion purposes.
