Other and unspecified myopathies (G72) ICD-10-CM
The G72 code range covers other and unspecified myopathies with 12 ICD-10-CM diagnosis codes. 9 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the G72 range.
Critical Illness Myopathy
Acute muscle weakness and paralysis that develops in critically ill patients who have been treated with multiple drugs during their intensive care unit stay. It is associated with delayed weaning from mechanical ventilation and prolonged rehabilitation.
Muscular Diseases
Acquired, familial, and congenital disorders of SKELETAL MUSCLE and SMOOTH MUSCLE.
Paralysis, Hyperkalemic Periodic
An autosomal dominant familial disorder which presents in infancy or childhood and is characterized by episodes of weakness associated with hyperkalemia. During attacks, muscles of the lower extremities are initially affected, followed by the lower trunk and arms. Episodes last from 15-60 minutes and typically occur after a period of rest following exercise. A defect in skeletal muscle sodium channels has been identified as the cause of this condition. Normokalemic periodic paralysis is a closely related disorder marked by a lack of alterations in potassium levels during attacks of weakness. (Adams et al., Principles of Neurology, 6th ed, p1481)
About the G72 Code Range
Myopathies are muscle diseases. This category includes myopathies linked to drugs, alcohol, other toxic agents, inflammation, immune processes, or critical illness, as well as periodic paralysis.
G72.0, G72.1, and G72.2 distinguish drugs, alcohol, and other toxic agents. G72.3 identifies periodic paralysis. Inflammatory and immune myopathies under G72.4 separate inclusion body myositis from other types. Other specified myopathies under G72.8 separate critical illness myopathy from other specified types. G72.9 is for unspecified myopathy.
