From the official ICD-10-CM alphabetic index entry “Dislocation (articular) › acromioclavicular (joint)”. Page updated September 29, 2026.
About coding acromioclavicular joint dislocation
The ICD-10-CM code for acromioclavicular joint dislocation is S43.10 (Unspecified dislocation of acromioclavicular joint). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S43.10.
Within S43.1, choose S43.10 (Unspecified dislocation of acromioclavicular joint) only when documentation doesn't support a more specific option: subluxation of acromioclavicular joint (S43.11), dislocation of acromioclavicular joint, 100%-200% displacement (S43.12), dislocation of acromioclavicular joint, greater than 200% displacement (S43.13), inferior dislocation of acromioclavicular joint (S43.14) and posterior dislocation of acromioclavicular joint (S43.15).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
