About ICD-9-CM 764.01
764.01 is an ICD-9-CM diagnosis code for "Light-for-dates" without mention of fetal malnutrition, less than 500 grams. 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 2 ICD-10-CM codes, such as P05.01 (Newborn light for gestational age, less than 500 grams) and P05.11 (Newborn small for gestational age, less than 500 grams). All of these are approximate matches, so review the record to pick the right one.
