Excludes2 inherited from the categories above L03.125
Also inherited, and the opposite of Excludes1: these conditions are not part of L03.125, but a patient can have both, so you may code both.

Other codes that can never be billed with L03.125
These codes carry an Excludes1 note pointing at L03.125. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading L03.125 alone.

Risk adjustment
L03.125 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.
Medicare coverage
L03.125 is named in 11 Medicare coverage policies — 11 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
