R82.9Other and unspecified abnormal findings in urine

R82.9 is the ICD-10-CM diagnosis code for other and unspecified 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 3 subcodes must be used instead.

Within R82, choose R82.9 (Other and unspecified abnormal findings in urine) only when documentation doesn't support a more specific option: Chyluria (R82.0), Myoglobinuria (R82.1), Biliuria (R82.2), 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) and 1 more.

To report this condition, pick the subcode that matches the documentation: R82.90 (urine), R82.91 (urine) and R82.99 (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 hasn't changed since.
