R82 is a non-billable ICD-10-CM category code for other and unspecified abnormal findings in urine, so it cannot be submitted on claims. Use a more specific code from this category instead, such as R82.0, R82.1, R82.2, and R82.3. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.

  • Use R82.2 for Biliuria

  • Use R82.3 for Hemoglobinuria

  • Use R82.4 for Acetonuria

  • Use R82.5 for Elevated urine levels of drugs, medicaments and biological substances

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

  • R82.7 for Abnormal findings on microbiological examination of urine

  • Use R82.71 for Bacteriuria

  • Use R82.79 for Other abnormal findings on microbiological examination of urine

  • R82.8 for Abnormal findings on cytological and histological examination of urine

  • Use R82.81 for Pyuria

  • Use R82.89 for Other abnormal findings on cytological and histological examination of urine

  • R82.9 for Other and unspecified abnormal findings in urine

  • Use R82.90 for Unspecified abnormal findings in urine

  • Use R82.91 for Other chromoabnormalities of urine

  • R82.99 for Other abnormal findings in urine

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to R82: its own notes plus those printed at block R80-R82 and Chapter 18. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

  • chromoabnormalities in urine

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

From Block R80-R82 Abnormal findings on examination of urine, without diagnosis applies to 25 codes
  • abnormal findings on antenatal screening of mother (O28.-)
  • diagnostic abnormal findings classified elsewhere - see Alphabetical Index
  • specific findings indicating disorder of amino-acid metabolism (E70-E72)
  • specific findings indicating disorder of carbohydrate metabolism (E73-E74)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

On R82 itself
From Chapter 18 (R00-R99) Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified applies to 774 codes
  • abnormal findings on antenatal screening of mother (O28.-)
  • certain conditions originating in the perinatal period (P04-P96)
  • signs and symptoms classified in the body system chapters
  • signs and symptoms of breast (N63, N64.5)

Use Additional Code

Add a second code, after this one, to fully describe the condition.

  • code to identify any retained foreign body, if applicable (Z18.-)

Notes

General instructions on how these codes are used.

From Chapter 18 (R00-R99) Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified applies to 774 codes
  • This chapter includes symptoms, signs, abnormal results of clinical or other investigative procedures, and ill-defined conditions regarding which no diagnosis classifiable elsewhere is recorded.
  • Signs and symptoms that point rather definitely to a given diagnosis have been assigned to a category in other chapters of the classification. In general, categories in this chapter include the less well-defined conditions and symptoms that, without the necessary study of the case to establish a final diagnosis, point perhaps equally to two or more diseases or to two or more systems of the body. Practically all categories in the chapter could be designated 'not otherwise specified', 'unknown etiology' or 'transient'. The Alphabetical Index should be consulted to determine which symptoms and signs are to be allocated here and which to other chapters. The residual subcategories, numbered .8, are generally provided for other relevant symptoms that cannot be allocated elsewhere in the classification.
  • The conditions and signs or symptoms included in categories R00-R94 consist of:
  • (a) cases for which no more specific diagnosis can be made even after all the facts bearing on the case have been investigated;
  • (b) signs or symptoms existing at the time of initial encounter that proved to be transient and whose causes could not be determined;
  • (c) provisional diagnosis in a patient who failed to return for further investigation or care;
  • (d) cases referred elsewhere for investigation or treatment before the diagnosis was made;
  • (e) cases in which a more precise diagnosis was not available for any other reason;
  • (f) certain symptoms, for which supplementary information is provided, that represent important problems in medical care in their own right.

Excludes2 1

These codes carry an Excludes2 note naming R82: its condition is not part of those codes, and both may be reported when the patient has both.

Patient EducationClinical

Urine and Urination

Your kidneys make urine by filtering wastes and extra water from your blood. The waste is called urea. Your blood carries it to the kidneys. From the kidneys, urine travels down two thin tubes called ureters to the bladder. The bladder stores urine until you are ready to urinate.

Questions About R82Overview

What is the ICD-10 code for other and unspecified abnormal findings in urine?

R82 is the ICD-10-CM category for other and unspecified abnormal findings in urine, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is R82 (Other and unspecified abnormal findings in urine) a billable code?

No. This is a category header that groups the codes for other and unspecified abnormal findings in urine, and headers cannot be submitted on claims. Claims for other and unspecified abnormal findings in urine need a more specific code from this category, such as R82.0, R82.1, and R82.2.

Can R82 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the other and unspecified abnormal findings in urine is established, that condition takes the principal position instead.

Can R82 be reported with a code from O28?

Not as a rule. The Excludes1 note at block R80-R82, which applies to R82, lists "abnormal findings on antenatal screening of mother (O28.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

Does R82 need an additional code?

When the condition applies, yes. The Use Additional Code note reads: code to identify any retained foreign body, if applicable (Z18.-). The additional code is reported after R82.
