R05.2 — Subacute cough
R05.2 is a billable, specific ICD-10-CM code for subacute cough. It is valid for submission on a claim.
Risk adjustment
R05.2 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
R05.2 is named in 22 Medicare coverage policies — 22 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
