R82.91 — Other chromoabnormalities of urine
R82.91 is a billable, specific ICD-10-CM code for other chromoabnormalities of urine. 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.
- Chromoconversion (dipstick)
- Idiopathic dipstick converts positive for blood with no cellular forms in sediment
Risk adjustment
R82.91 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 R82.91 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 R82.91.
