R82.99Other abnormal findings in urine

R82.99 is the ICD-10-CM diagnosis code for other abnormal findings in urine. 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 a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

Within R82.9, choose R82.99 (Other abnormal findings in urine) only when documentation doesn't support a more specific option: unspecified abnormal findings in urine (R82.90) and other chromoabnormalities of urine (R82.91).

To report this condition, pick the subcode that matches the documentation: R82.991 (Hypocitraturia), R82.992 (hyperoxaluria), R82.993 (Hyperuricosuria), R82.994 (Hypercalciuria) and R82.998 (urine).

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

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2019 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 791.7 (other cells and casts in urine) and 791.9 (other nonspecific findings on examination of urine).
