About ICD-9-CM 271.8
271.8 is an ICD-9-CM diagnosis code for other specified disorders of carbohydrate transport and metabolism. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 5 ICD-10-CM codes, such as E72.52 (Trimethylaminuria), E72.53 (Primary hyperoxaluria) and E74.4 (Disorders of pyruvate metabolism and gluconeogenesis). All of these are approximate matches, so review the record to pick the right one.
