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 2026, 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.
Hemoglobinuria, Paroxysmal
A condition characterized by the recurrence of HEMOGLOBINURIA caused by intravascular HEMOLYSIS. In cases occurring upon cold exposure (paroxysmal cold hemoglobinuria), usually after infections, there is a circulating antibody which is also a cold hemolysin. In cases occurring during or after sleep (paroxysmal nocturnal hemoglobinuria), the clonal hematopoietic stem cells exhibit a global deficiency of cell membrane proteins.
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.
Hyperoxaluria, Primary
A genetic disorder characterized by excretion of large amounts of OXALATES in urine; NEPHROLITHIASIS; NEPHROCALCINOSIS; early onset of RENAL FAILURE; and often a generalized deposit of CALCIUM OXALATE. There are subtypes classified by the enzyme defects in glyoxylate metabolism.
Myoglobinuria
The presence of MYOGLOBIN in URINE usually as a result of rhabdomyolysis.
Oxalates
Derivatives of OXALIC ACID. Included under this heading are a broad variety of acid forms, salts, esters, and amides that are derived from the ethanedioic acid structure.
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.
Urinary Tract
The duct which coveys URINE from the pelvis of the KIDNEY through the URETERS, BLADDER, and URETHRA.
About the R82 Code Range
The ICD-10 code R82 category covers various abnormal findings detected in urine that do not fall into better-defined diagnostic categories. These codes help health professionals identify and document unusual urine test results that may indicate underlying medical conditions or exposure to substances.
The specific codes within R82 include detailed abnormalities such as R82.0 (Chyluria), characterized by fat globules in urine; R82.1 (Myoglobinuria), indicating presence of myoglobin often related to muscle injury; and R82.2 (Biliuria), which involves abnormal bilirubin in urine. Other codes address findings like hemoglobinuria, acetonuria, and elevated drug or substance levels in urine. For instance, R82.71 codes for bacteriuria, the presence of bacteria in urine, while R82.81 denotes pyuria, or pus cells in urine. These distinctions help coders assign the accurate ICD-10 code for abnormal urine findings such as “fat globules in urine” or “urine ketone test positive.”
Additionally, codes like R82.9X cover unspecified or other abnormal urine findings such as unusual urine color, crystals, or casts. Using the correct ICD-10 code for abnormal urine findings is essential for accurately documenting abnormalities detected through urinalysis, microbiological, cytological, or chemical urine tests, supporting proper diagnosis and treatment planning.
