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.
