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 R82.2Overview

Is R82.2 (Other and unspecified abnormal findings in urine) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report biliuria on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

When biliuria is the principal diagnosis on an inpatient stay, it groups to MS-DRG 441, 442, 443, with relative weights from 0.6997 to 1.7947 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R82.2 be a principal diagnosis?

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

What is the ICD-9 equivalent of R82.2?

Under the General Equivalence Mappings, biliuria converts to ICD-9-CM 791.4 (biliuria). The mapping is a direct match.

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.
