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.

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.G13.2 is a billable ICD code used to specify a diagnosis of systemic atrophy primarily affecting the central nervous system in myxedema.
