About G71.0

G71.0 is the ICD-10-CM diagnosis code for muscular dystrophy. 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 5 subcodes must be used instead.

Within G71 (primary disorders of muscles), G71.0 is specifically for muscular dystrophy. Related codes cover myotonic disorders (G71.1), congenital myopathies (G71.2), mitochondrial myopathy, not elsewhere classified (G71.3), other primary disorders of muscles (G71.8) and primary disorder of muscle, unspecified (G71.9).

To report this condition, pick the subcode that matches the documentation: G71.00 (unspecified), G71.01 (dystrophy), G71.02 (dystrophy), G71.03 (dystrophies) and G71.09 (dystrophies).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2019 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 359.1 (hereditary progressive muscular dystrophy).
