Other and unspecified abnormal findings in urine (R82)

Browse all the diagnosis codes used for other and unspecified abnormal findings in urine (r82). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

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.

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
