About R82

R82 is the ICD-10-CM diagnosis code for other and unspecified abnormal findings in urine. It belongs to 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 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: R82.0 (Chyluria), R82.1 (Myoglobinuria), R82.2 (Biliuria), R82.3 (hemoglobinuria), R82.4 (Acetonuria), R82.5 (substances), R82.6 (source), R82.7 (urine) and 2 more.

The conditions in its Excludes2 note aren't part of R82, but may be coded alongside it if the patient has both: hematuria (R31.-).

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 hasn't changed since.
