R81 — Glycosuria

Billable / specific codeICD-10-CM

R81 is a billable, specific ICD-10-CM code for glycosuria. 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.

renal glycosuria (E74.818)

Other codes that can never be billed with R81

These codes carry an Excludes1 note pointing at R81. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R81 alone.

Risk adjustment

R81 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.

How R81 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to R81.
