About ICD-9-CM 172.1
172.1 is an ICD-9-CM diagnosis code for malignant melanoma of skin of eyelid, including canthus. 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 4 ICD-10-CM codes, such as C43.10 (Malignant melanoma of unspecified eyelid, including canthus), D03.10 (Melanoma in situ of unspecified eyelid, including canthus) and D03.11 (Melanoma in situ of right eyelid, including canthus). All of these are approximate matches, so review the record to pick the right one.
