R20.2 — Paresthesia of skin
R20.2 is a billable, specific ICD-10-CM code for paresthesia of skin. It is valid for submission on a claim.

Excludes1 inherited from the categories above R20.2
These are not written on R20.2, but they bind it: a note on a category applies to every code beneath it. Billing R20.2 with anything listed here is a denial.
Risk adjustment
R20.2 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
R20.2 is named in 30 Medicare coverage policies — 28 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.
