R82

Other and unspecified abnormal findings in urine

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

Code Description

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

Key Diagnostic Point:

The ICD-10 code R82 encompasses a range of abnormal findings in urine that do not fall under more specific categories. This may include findings such as abnormal urine color, turbidity, specific gravity, pH, presence of crystals, or other constituents that are not classified elsewhere. These findings can indicate various underlying conditions, including urinary tract infections, kidney disease, metabolic disorders, or dehydration. The clinical significance of these findings often requires further investigation to determine the underlying cause. For instance, hematuria (blood in urine) may suggest trauma or malignancy, while proteinuria (excess protein) can indicate kidney dysfunction. Accurate documentation of the specific abnormal findings is crucial for appropriate coding and subsequent management.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of potential underlying conditions
  • Need for precise documentation of abnormal findings
  • Differentiation from more specific codes
  • Potential overlap with other urinary symptoms

Audit Risk Factors

  • Insufficient documentation of abnormal findings
  • Failure to specify the clinical context
  • Inconsistent coding practices across providers
  • Misuse of R82 when more specific codes are applicable

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Detailed notes on the patient's history, physical examination findings, and any laboratory results related to urine analysis.

Common Clinical Scenarios

Patients presenting with nonspecific urinary symptoms, abnormal lab results during routine check-ups, or follow-up visits for chronic conditions.

Billing Considerations

Ensure that all abnormal findings are clearly documented and linked to the patient's clinical picture to support the use of R82.

Emergency Medicine

Documentation Requirements

Acute care documentation must include the patient's presenting symptoms, any immediate lab results, and the rationale for further testing.

Common Clinical Scenarios

Patients with acute abdominal pain, hematuria, or signs of urinary tract infection presenting to the emergency department.

Billing Considerations

In emergency settings, rapid assessment and documentation of abnormal findings are critical for appropriate coding and treatment.

Coding Guidelines

Inclusion Criteria

Use R82 When
  • Follow the official ICD
  • CM coding guidelines, ensuring that the code is used only when the abnormal findings cannot be classified under more specific codes
  • Document the clinical context and rationale for the findings

Exclusion Criteria

Do NOT use R82 When
No specific exclusions found.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more detailed coding of urinary findings, enabling better tracking of conditions and outcomes. R82 provides a catch-all for abnormal findings that do not fit into more specific categories, but it requires careful documentation to avoid misclassification.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more detailed coding of urinary findings, enabling better tracking of conditions and outcomes. R82 provides a catch-all for abnormal findings that do not fit into more specific categories, but it requires careful documentation to avoid misclassification.

Reimbursement & Billing Impact

Frequently Asked Questions

When should I use R82 instead of more specific codes?

Use R82 when the abnormal findings in urine cannot be classified under more specific codes like R80 or R81, and ensure that the clinical context is well documented.
