About ICD-9-CM 275.1
275.1 is an ICD-9-CM diagnosis code for disorders of copper 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 3 ICD-10-CM codes, such as E83.00 (Disorder of copper metabolism, unspecified), E83.01 (Wilson's disease) and E83.09 (Other disorders of copper metabolism). All of these are approximate matches, so review the record to pick the right one.
