About ICD-9-CM 831.10

831.10 is an ICD-9-CM diagnosis code for open dislocation of shoulder, unspecified. 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 S41.009A (Unspecified open wound of unspecified shoulder, initial encounter) and S43.006A (Unspecified dislocation of unspecified shoulder joint, initial encounter). All of these are approximate matches, so review the record to pick the right one. Some mappings are combinations: more than one ICD-10 code is needed to fully express the ICD-9 code.
