T85.4 — Mechanical complication of breast prosthesis and implant
T85.4 is a non-billable header ICD-10-CM code for mechanical complication of breast prosthesis and implant. 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 T85
- A
- initial encounter
- D

- S
- sequela
Other codes that can never be billed with T85.4
These codes carry an Excludes1 note pointing at T85.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T85.4 alone.
Risk adjustment
T85.4 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.
Code to one of these instead T85.4
5 child codes. Green means billable.
