About coding shoulder joint sprain
The ICD-10-CM code for shoulder joint sprain is S43.40 (Unspecified sprain of shoulder joint). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S43.40.
Within S43.4, choose S43.40 (Unspecified sprain of shoulder joint) only when documentation doesn't support a more specific option: sprain of coracohumeral (ligament) (S43.41), sprain of rotator cuff capsule (S43.42), superior glenoid labrum lesion (S43.43) and other sprain of shoulder joint (S43.49).
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.
