About coding Fava bean toxicity
The ICD-10-CM code for Fava bean toxicity is D55.0 (Anemia due to glucose-6-phosphate dehydrogenase [G6PD] deficiency).
Within D55 (anemia due to enzyme disorders), D55.0 is specifically for anemia due to glucose-6-phosphate dehydrogenase [G6PD] deficiency. Related codes cover anemia due to other disorders of glutathione metabolism (D55.1), anemia due to disorders of glycolytic enzymes (D55.2), anemia due to disorders of nucleotide metabolism (D55.3), other anemias due to enzyme disorders (D55.8) and anemia due to enzyme disorder, unspecified (D55.9).
Don't report D55.0 together with the conditions in its Excludes1 note: glucose-6-phosphate dehydrogenase (G6PD) deficiency without anemia (D75.A).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for D55.0)
- glucose-6-phosphate dehydrogenase (G6PD) deficiency without anemia (D75.A)
