About ICD-9-CM 366.09
366.09 is an ICD-9-CM diagnosis code for other and combined forms of nonsenile cataract. 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 H26.069 (Combined forms of infantile and juvenile cataract, unspecified eye) and H26.09 (Other infantile and juvenile cataract). All of these are approximate matches, so review the record to pick the right one.
