R82.90

Unspecified abnormal findings in urine

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R82.90 is a billable code used to indicate a diagnosis of unspecified abnormal findings in urine.

Key Diagnostic Point:

R82.90 is used to classify unspecified abnormal findings in urine that do not fall under a more specific diagnosis. This code encompasses a variety of potential abnormalities that may be detected during urinalysis, including but not limited to the presence of blood (hematuria), protein (proteinuria), glucose (glycosuria), ketones, or abnormal pH levels. These findings can indicate a range of underlying conditions, from urinary tract infections (UTIs) and kidney disease to metabolic disorders and systemic diseases. The lack of specificity in this code necessitates careful clinical evaluation to determine the underlying cause of the abnormal findings. Clinicians may order additional tests, such as urine cultures, imaging studies, or blood tests, to further investigate the etiology of the abnormalities. Accurate documentation of the clinical context, symptoms, and any follow-up actions taken is crucial for proper coding and billing.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation and underlying causes
  • Need for comprehensive documentation to support the diagnosis
  • Potential overlap with other urinary conditions requiring specific codes
  • Interpretation of laboratory results can vary among clinicians

Audit Risk Factors

  • Inadequate documentation supporting the diagnosis
  • Use of unspecified codes without clear clinical rationale
  • Failure to follow up on abnormal findings
  • Inconsistent coding practices among providers

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Detailed clinical notes explaining the reason for urinalysis, findings, and any follow-up actions taken.

Common Clinical Scenarios

Patients presenting with symptoms such as flank pain, dysuria, or unexplained weight loss may undergo urinalysis, leading to abnormal findings.

Billing Considerations

Ensure that all relevant symptoms and potential underlying conditions are documented to support the use of R82.90.

Emergency Medicine

Documentation Requirements

Acute care documentation must include the patient's presenting symptoms, the rationale for urinalysis, and any immediate interventions.

Common Clinical Scenarios

Patients with acute abdominal pain or suspected renal colic may have urinalysis performed, revealing abnormal findings.

Billing Considerations

In emergency settings, rapid documentation is essential, but it must still capture the necessary details to justify the use of R82.90.

Coding Guidelines

Inclusion Criteria

Use R82.90 When
  • According to ICD
  • 10 coding guidelines, R82
  • 90 should be used when the abnormal findings in urine are not specified elsewhere
  • Coders must ensure that the clinical documentation supports the use of this code and that no more specific codes are applicable

Exclusion Criteria

Specialty Considerations

In internal medicine, ensure that the clinical context is clear to support the findings.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more detailed coding, but it has also introduced complexity with unspecified codes like R82.90. Coders must be diligent in ensuring that the use of this code is justified by the clinical documentation.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more detailed coding, but it has also introduced complexity with unspecified codes like R82.90. Coders must be diligent in ensuring that the use of this code is justified by the clinical documentation.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more detailed coding, but it has also introduced complexity with unspecified codes like R82.90. Coders must be diligent in ensuring that the use of this code is justified by the clinical documentation.
