About coding Variance
The ICD-10-CM code for Variance is T82.09 (Other mechanical complication of heart valve prosthesis).
Within T82.0, choose T82.09 (Other mechanical complication of heart valve prosthesis) only when documentation doesn't support a more specific option: breakdown (mechanical) of heart valve prosthesis (T82.01), displacement of heart valve prosthesis (T82.02) and leakage of heart valve prosthesis (T82.03).
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.
