About ICD-9-CM 524.61
524.61 is an ICD-9-CM diagnosis code for temporomandibular joint disorders, adhesions and ankylosis (bony or fibrous). 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 M26.611 (Adhesions and ankylosis of right temporomandibular joint), M26.612 (Adhesions and ankylosis of left temporomandibular joint) and M26.613 (Adhesions and ankylosis of bilateral temporomandibular joint). All of these are approximate matches, so review the record to pick the right one.
