What is the correct ICD-9 code to use for G6PD (Glucose-6-phosphate dehydrogenase deficiency)?
Using deficiency as the main term in the ICD-9 CM index ,
there is a subterm Glucose-6-phosphate dehydrogenase anemia ,
code 282.2. anemias due to disorders of glutathione metabolism. This code does not seem accurate when there is no documentation of an anemia.
there is also a subterm enzymes, circulating NEC
code 277.6 other deficiencies of circulating enzymes
This code may not be accurate because glucose-6-phosphate dehydrogenase is considered an enzyme but it is not described as a circulating enzyme
Considering the narrative for code 282.2 anemias due to disorders of glutathione metabolism, should the main term be disorder , subterm metabolism NEC,
code 277.9 unspecified disorder of metabolism
Thank you for any assistance you can give.
