K62.82 — Dysplasia of anus
K62.82 is a billable, specific ICD-10-CM code for dysplasia of anus. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Anal intraepithelial neoplasia I and II (AIN I and II) (histologically confirmed)
- Dysplasia of anus NOS
- Mild and moderate dysplasia of anus (histologically confirmed)
Other codes that can never be billed with K62.82
These codes carry an Excludes1 note pointing at K62.82. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K62.82 alone.
Risk adjustment
K62.82 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
K62.82 is named in 7 Medicare coverage policies — 7 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
