About ICD-9-CM 717.1
717.1 is an ICD-9-CM diagnosis code for derangement of anterior horn of medial meniscus. 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 M23.219 (Derangement of anterior horn of medial meniscus due to old tear or injury, unspecified knee) and M23.319 (Other meniscus derangements, anterior horn of medial meniscus, unspecified knee). All of these are approximate matches, so review the record to pick the right one.
