Glucose 6 Dehydrogenase Deficiency

Glucose 6 dehydrogenase deficiency (G6PD deficiency) is a genetic disorder that affects red blood cells. Red blood cells are responsible for carrying oxygen throughout the body, and G6PD deficiency can cause them to break down prematurely. This can lead to a number of health problems, including hemolytic anemia, which is a type of anemia in which the body does not have enough healthy red blood cells.


G6PD deficiency is caused by a mutation in the G6PD gene. This gene is responsible for producing the enzyme glucose 6 dehydrogenase, which helps protect red blood cells from damage. When the G6PD gene is mutated, the body cannot produce enough glucose 6 dehydrogenase, which makes red blood cells more susceptible to damage.


The symptoms of G6PD deficiency can vary depending on the severity of the deficiency. Some people with G6PD deficiency may have no symptoms, while others may experience symptoms such as:

  • Fatigue
  • Paleness
  • Yellowing of the skin and eyes (jaundice)
  • Dark urine
  • Shortness of breath
  • Rapid heart rate


There is no cure for G6PD deficiency, but treatment can help to manage the symptoms. Treatment may include:

  • Avoiding triggers that can cause red blood cell damage, such as certain infections, drugs, and foods
  • Taking blood transfusions to replace red blood cells that have been destroyed
  • Taking medications to prevent or treat anemia


There is no way to prevent G6PD deficiency, but it is possible to reduce the risk of complications by avoiding triggers that can cause red blood cell damage.


G6PD deficiency is a common genetic disorder that can cause a number of health problems. There is no cure for G6PD deficiency, but treatment can help to manage the symptoms. By avoiding triggers that can cause red blood cell damage, people with G6PD deficiency can reduce the risk of complications.

The ICD-10 code D55.0 is used to classify G6PD deficiency, which stands for “Glucose-6-Phosphate Dehydrogenase deficiency.” Let’s break down the code:

  • D: This is the category code for “Certain disorders involving the immune mechanism.” G6PD deficiency is classified under this category as it is an inherited disorder related to the immune system.
  • 55: This is the subcategory code for “Enzyme deficiencies.” G6PD deficiency is specifically classified as an enzyme deficiency because it involves the insufficient activity of the G6PD enzyme.
  • 0: This is the extension code for “Glucose-6-Phosphate Dehydrogenase deficiency.” It specifies the specific condition within the subcategory of enzyme deficiencies.

Together, the code D55.0 represents the classification of G6PD deficiency within the ICD-10 coding system. This code helps healthcare professionals and medical coders accurately identify and document cases of G6PD deficiency for medical records, statistical analysis, and reimbursement purposes.
