About R82.2

R82.2 is the ICD-10-CM diagnosis code for Biliuria. It belongs to category R82 (other and unspecified abnormal findings in urine), block R80-R82 (abnormal findings on examination of urine, without diagnosis) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within R82 (other and unspecified abnormal findings in urine), R82.2 is specifically for Biliuria. Related codes cover Chyluria (R82.0), Myoglobinuria (R82.1), hemoglobinuria (R82.3), Acetonuria (R82.4), elevated urine levels of drugs, medicaments and biological substances (R82.5), abnormal urine levels of substances chiefly nonmedicinal as to source (R82.6), abnormal findings on microbiological examination of urine (R82.7), abnormal findings on cytological and histological examination of urine (R82.8) and 1 more.

Use an additional code to identify any retained foreign body, if applicable (Z18.-).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 441 (Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis with MCC, relative weight 1.8219), DRG 442 (Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis with CC, relative weight 0.9602) and DRG 443 (Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis without CC/MCC, relative weight 0.6885), in MDC 07 (Diseases and Disorders of the Hepatobiliary System and Pancreas), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 791.4 (Biliuria).
