About coding patella subluxation
The ICD-10-CM code for patella subluxation is S83.00 (Unspecified subluxation and dislocation of patella). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S83.00.
Within S83.0, choose S83.00 (Unspecified subluxation and dislocation of patella) only when documentation doesn't support a more specific option: lateral subluxation and dislocation of patella (S83.01) and other subluxation and dislocation of patella (S83.09).
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.
