Excludes2 inherited from the categories above L03.317

Other codes that can never be billed with L03.317
These codes carry an Excludes1 note pointing at L03.317. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading L03.317 alone.
- I89.1Lymphangitis
Risk adjustment
L03.317 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
L03.317 is named in 8 Medicare coverage policies — 8 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
