T32.0 — Corrosions involving less than 10% of body surface
T32.0 is a billable, specific ICD-10-CM code for corrosions involving less than 10% of body surface. It is valid for submission on a claim.
Risk adjustment
T32.0 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
T32.0 is named in 9 Medicare coverage policies — 7 listing it as supporting medical necessity, and 2 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
