R82.6Abnormal urine levels of substances chiefly nonmedicinal as to source

R82.6 is the ICD-10-CM diagnosis code for abnormal urine levels of substances chiefly nonmedicinal as to source. 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 (other and unspecified abnormal findings in urine), R82.6 is specifically for abnormal urine levels of substances chiefly nonmedicinal as to source. Related codes cover 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 findings on microbiological examination of urine (R82.7), abnormal findings on cytological and histological examination of urine (R82.8) and 1 more.

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 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 791.9 (other nonspecific findings on examination of urine) and 796.0 (nonspecific abnormal toxicological findings).
