About R82.71
R82.71 is the ICD-10-CM diagnosis code for bacteriuria. 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 R82.7 (abnormal findings on microbiological examination of urine), R82.71 is specifically for bacteriuria. Related codes cover other abnormal findings on microbiological examination of urine (R82.79).
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 695 (Kidney and Urinary Tract Signs and Symptoms with MCC, relative weight 1.1139) and DRG 696 (Kidney and Urinary Tract Signs and Symptoms without MCC, relative weight 0.6679), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), 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 was added in FY2017, effective October 1, 2016.
Before ICD-10, this condition was coded in ICD-9-CM as 791.9 (other nonspecific findings on examination of urine).
