This code requires a 7th character
The appropriate 7th character is to be added to each code from category T45
- A
- initial encounter
- D

T45.7X6 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 T45.7X6
3 child codes. Green means billable.
