About ICD-9-CM 365.11
365.11 is an ICD-9-CM diagnosis code for primary open angle glaucoma. 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 20 ICD-10-CM codes, such as H40.1110 (Primary open-angle glaucoma, right eye, stage unspecified), H40.1111 (Primary open-angle glaucoma, right eye, mild stage) and H40.1112 (Primary open-angle glaucoma, right eye, moderate stage). All of these are approximate matches, so review the record to pick the right one.
