ICD-10-CM R82.998
CMSSource: CMS FY 2026 ICD-10-CM dataset · Effective Oct 1, 2025 – Sep 30, 2026

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 2026 (October 1, 2025 through September 30, 2026) 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.

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).

  • Melanuria

    an indication of dark brown or black urine discoloration due to the presence of melanin or its precursors.

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

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, 2025 through September 30, 2026.

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 695, 696, with relative weights from 0.6890 to 1.1438 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.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
