L73.2 — Hidradenitis suppurativa
L73.2 is a billable, specific ICD-10-CM code for hidradenitis suppurativa. It is valid for submission on a claim.
Other codes that can never be billed with L73.2
These codes carry an Excludes1 note pointing at L73.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading L73.2 alone.

Risk adjustment
L73.2 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
L73.2 is named in 3 Medicare coverage policies — 3 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
