Other and unspecified abnormal findings in urine (R82)

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.

Instructional Notations

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

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

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.
