About coding knee dislocation
The ICD-10-CM code for knee dislocation is S83.106 (Unspecified dislocation of unspecified knee). The official index lists 7 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S83.106.
Within S83.10, choose S83.106 (dislocation of unspecified knee) only when documentation doesn't support a more specific option: subluxation of right knee (S83.101), subluxation of left knee (S83.102), subluxation of unspecified knee (S83.103), dislocation of right knee (S83.104) and dislocation of left knee (S83.105).
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.
