About R88.0

R88.0 is the ICD-10-CM diagnosis code for Cloudy (hemodialysis) (peritoneal) dialysis effluent. It belongs to category R88 (abnormal findings in other body fluids and substances), block R83-R89 (abnormal findings on examination of other body fluids, substances and tissues, 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 R88 (abnormal findings in other body fluids and substances), R88.0 is specifically for Cloudy (hemodialysis) (peritoneal) dialysis effluent. Related codes cover abnormal findings in other body fluids and substances (R88.8).

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 947 (Signs and Symptoms with MCC, relative weight 1.261) and DRG 948 (Signs and Symptoms without MCC, relative weight 0.7835), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), 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 792.5 (Cloudy (hemodialysis) (peritoneal) dialysis effluent).
