CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

R82.998 is a billable ICD-10-CM diagnosis code for other abnormal findings in urine. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 695 through 696. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Genitourinary signs and symptoms.

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.

Clinical InformationClinical

  • 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).

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 R82.998Overview

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

The ICD-10-CM code for other abnormal findings in urine is R82.998 (sometimes written as R82998). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is R82.998 (Other abnormal findings in urine) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other abnormal findings in urine on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does R82.998 group to?

When other abnormal findings in urine is the principal diagnosis on an inpatient stay, it groups to MS-DRG 696, 695, with relative weights from 0.6677 to 1.1136 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R82.998 be a principal diagnosis?

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

Can R82.998 be reported with a code from O28?

Not as a rule. The Excludes1 note at block R80-R82, which applies to R82.998, 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).
