About G73

G73 is the ICD-10-CM diagnosis code for disorders of myoneural junction and muscle in diseases classified elsewhere. It belongs to block G70-G73 (diseases of myoneural junction and muscle) and chapter 6 (diseases of the nervous system). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: G73.1 (disease), G73.3 (elsewhere) and G73.7 (elsewhere).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
