ICD-10-CM Code G71.3

Mitochondrial myopathy, not elsewhere classified

Version 2020 Billable Code

Valid for Submission

G71.3 is a billable code used to specify a medical diagnosis of mitochondrial myopathy, not elsewhere classified. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code G71.3 might also be used to specify conditions or terms like adult-onset chronic progressive external ophthalmoplegia with mitochondrial myopathy, adult-onset multiple mitochondrial deoxyribonucleic acid deletion syndrome due to deoxyguanosine kinase deficiency, childhood myocerebrohepatopathy spectrum, congenital cataract, hypertrophic cardiomyopathy, mitochondrial myopathy syndrome, fastkd2-related infantile mitochondrial encephalomyopathy, fbxl4-related encephalomyopathic mitochondrial dna depletion syndrome, etc

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code G71.3:

Type 1 Excludes

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.
  • Kearns-Sayre syndrome H49.81
  • Leber's disease H47.21
  • Leigh's encephalopathy G31.82
  • mitochondrial metabolism disorders E88.4
  • Reye's syndrome G93.7

Information for Patients


Mitochondrial Diseases

Metabolism is the process your body uses to make energy from the food you eat. Food is made up of proteins, carbohydrates, and fats. Chemicals in your digestive system (enzymes) break the food parts down into sugars and acids, your body's fuel. Your body can use this fuel right away, or it can store the energy in your body tissues. If you have a metabolic disorder, something goes wrong with this process.

Mitochondrial diseases are a group of metabolic disorders. Mitochondria are small structures that produce energy in almost all of your cells. They make it by combining oxygen with the fuel molecules (sugars and fats) that come from your food. When the mitochondria are defective, the cells do not have enough energy. The unused oxygen and fuel molecules build up in the cells and cause damage.

The symptoms of mitochondrial disease can vary. It depends on how many mitochondria are defective, and where they are in the body. Sometimes only one organ, tissue, or cell type is affected. But often the problem affects many of them. Muscle and nerve cells have especially high energy needs, so muscular and neurological problems are common. The diseases range from mild to severe. Some types can be fatal.

Genetic mutations cause these diseases. They usually happen before age 20, and some are more common in infants. There are no cures for these diseases, but treatments may help with symptoms and slow down the disease. They may include physical therapy, vitamins and supplements, special diets, and medicines.
