About ICD-9-CM 790.6
790.6 is an ICD-9-CM diagnosis code for other abnormal blood chemistry. 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 3 ICD-10-CM codes, such as R78.89 (Finding of other specified substances, not normally found in blood), R79.0 (Abnormal level of blood mineral) and R79.89 (Other specified abnormal findings of blood chemistry). All of these are approximate matches, so review the record to pick the right one.
