T84.2 — Mechanical complication of internal fixation device of other bones
T84.2 is a non-billable header ICD-10-CM code for mechanical complication of internal fixation device of other bones. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.
This code requires a 7th character
The appropriate 7th character is to be added to each code from category T84
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Other codes that can never be billed with T84.2
These codes carry an Excludes1 note pointing at T84.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T84.2 alone.
- T85.612Breakdown (mechanical) of permanent sutures
- T85.622ADisplacement of permanent sutures, initial encounter
- T85.612ABreakdown (mechanical) of permanent sutures, initial encounter
- T85.612DBreakdown (mechanical) of permanent sutures, subsequent encounter
- T85.612SBreakdown (mechanical) of permanent sutures, sequela
- T85.622Displacement of permanent sutures
- T85.622DDisplacement of permanent sutures, subsequent encounter
- T85.622SDisplacement of permanent sutures, sequela
Risk adjustment
T84.2 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
