717.3 — Other and unspecified derangement of medial meniscus
About ICD-9-CM 717.3
717.3 is an ICD-9-CM diagnosis code for other and unspecified derangement 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 3 ICD-10-CM codes, such as M23.239 (Derangement of other medial meniscus due to old tear or injury, unspecified knee), M23.305 (Other meniscus derangements, unspecified medial meniscus, unspecified knee) and M23.339 (Other meniscus derangements, other medial meniscus, unspecified knee). All of these are approximate matches, so review the record to pick the right one.
