ICD-10 Code D75.A – Glucose-6-phosphate dehydrogenase (G6PD) deficiency without anemia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D75.A – Glucose-6-phosphate dehydrogenase (G6PD) deficiency without anemia
What it is
D75.A identifies an inherited G6PD enzyme deficiency when anemia is not documented. Use it for patients with confirmed G6PD deficiency who are not currently described as anemic.
Clinical signs
Clinical features vary; refer to documentation. Patients may be asymptomatic or have a history of hemolysis triggered by certain medications, infections, or foods, but the record must support deficiency without anemia.
When to use this code
Use D75.A when the clinician documents G6PD deficiency and does not diagnose anemia. It also fits follow-up visits, screening results, or problem-list entries that confirm the enzyme deficiency without current anemia. If hemolytic anemia is present, check documentation for a more specific code.
Do not use for
Do not use this code when anemia is documented with the deficiency. Also avoid it for nonspecific hemolysis, other hemolytic disorders, or unconfirmed suspected G6PD deficiency.
Coding tip
Code the condition exactly as documented, and verify whether anemia or hemolysis is separately reported.
