R84.6 — Abnormal cytological findings in specimens from respiratory organs and thorax
R84.6 is a billable, specific ICD-10-CM code for abnormal cytological findings in specimens from respiratory organs and thorax. It is valid for submission on a claim.
Risk adjustment
R84.6 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
R84.6 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
