About G71.22

G71.22 is the ICD-10-CM diagnosis code for centronuclear myopathy. It belongs to category G71 (primary disorders of muscles), 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 2 subcodes must be used instead.

Within G71.2 (congenital myopathies), G71.22 is specifically for centronuclear myopathy. Related codes cover congenital myopathy, unspecified (G71.20), Nemaline myopathy (G71.21) and other congenital myopathy (G71.29).

To report this condition, pick the subcode that matches the documentation: G71.220 (myopathy) and G71.228 (myopathy).

It was added in FY2021, effective October 1, 2020.
