Add a secondary code to capture the detail described below.

Other codes that can never be billed with K73
These codes carry an Excludes1 note pointing at K73. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K73 alone.
Risk adjustment
K73 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 K73
5 child codes. Green means billable.
