Other and unspecified abnormal findings in urine (R82) ICD-10-CM
The R82 code range covers other and unspecified abnormal findings in urine with 23 ICD-10-CM diagnosis codes. 18 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- chromoabnormalities in urine
Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
- code to identify any retained foreign body, if applicable Z18
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
- hematuria R31

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the R82 range.
Bacteriuria
The presence of bacteria in the urine which is normally bacteria-free. These bacteria are from the URINARY TRACT and are not contaminants of the surrounding tissues. Bacteriuria can be symptomatic or asymptomatic. Significant bacteriuria is an indicator of urinary tract infection.
Crystalluria
Crystals in the URINE found in urinary sediment analysis. Urinary crystalline may be formed from various metabolites (e.g. CALCIUM OXALATES; CALCIUM PHOSPHATES; URATES) and drugs (e.g., SULPHADIAZINE; ACYCLOVIR; and TRIAMTERENE).
Hemoglobinuria
The presence of free HEMOGLOBIN in the URINE, indicating hemolysis of ERYTHROCYTES within the vascular system. After saturating the hemoglobin-binding proteins (HAPTOGLOBINS), free hemoglobin begins to appear in the urine.
Hypercalciuria
Excretion of abnormally high level of CALCIUM in the URINE, greater than 4 mg/kg/day.
Hyperoxaluria
Excretion of an excessive amount of OXALATES in the urine.
Myoglobinuria
The presence of MYOGLOBIN in URINE usually as a result of rhabdomyolysis.
Pyuria
The presence of white blood cells (LEUKOCYTES) in the urine. It is often associated with bacterial infections of the urinary tract. Pyuria without BACTERIURIA can be caused by TUBERCULOSIS, stones, or cancer.
About the R82 Code Range
These are abnormal findings from urine examinations when no diagnosis is given, including findings described as other or unspecified.
The subdivisions separate named findings from elevated drug-related substances and abnormal levels of substances chiefly from nonmedicinal sources. They also distinguish microbiological findings (R82.7) from findings on cell and tissue examination (R82.8). Within the microbiological group, R82.71 identifies bacteriuria, or bacteria in urine. Other and unspecified findings fall under R82.9, with further distinctions for urine color abnormalities and particular substances in urine.
