ICD-10-CM Code G71.3
Mitochondrial myopathy, not elsewhere classified
Billable CodeBillable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
G71.3 is a billable ICD code used to specify a diagnosis of mitochondrial myopathy, not elsewhere classified. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code G713 is used to code Mitochondrial myopathy
Mitochondrial myopathies are types of myopathies associated with mitochondrial disease. On biopsy, the muscle tissue of patients with these diseases usually demonstrate "ragged red" muscle fibers. These ragged-red fibers contain mild accumulations of glycogen and neutral lipids, and may show an increased reactivity for succinate dehydrogenase and a decreased reactivity for cytochrome c oxidase. Inheritance is maternal (non-Mendelian extranuclear). There are several subcategories of mitochondrial myopathies.
