R82.4

Acetonuria

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

Code Description

ICD-10 R82.4 is a billable code used to indicate a diagnosis of acetonuria.

Key Diagnostic Point:

Acetonuria refers to the presence of acetone in the urine, which is a ketone body produced during the metabolism of fats. This condition is often indicative of a state of ketosis, which can occur in various clinical scenarios, including uncontrolled diabetes mellitus, prolonged fasting, or a low-carbohydrate diet. Patients may present with symptoms such as fruity-smelling breath, nausea, vomiting, and abdominal pain. Laboratory findings typically reveal elevated ketone levels in the urine, which can be detected using urine dipstick tests. Acetonuria is not a standalone diagnosis but rather a symptom that requires further investigation to determine the underlying cause. It is crucial for healthcare providers to assess the patient's overall clinical picture, including blood glucose levels and metabolic status, to guide appropriate management and treatment. Understanding the context of acetonuria is essential for accurate coding and effective patient care.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of metabolic processes and conditions leading to ketosis.
  • Differentiation from other causes of ketonuria.
  • Need for comprehensive patient history and laboratory results.
  • Potential overlap with other ICD codes related to metabolic disorders.

Audit Risk Factors

  • Inadequate documentation of the underlying cause of acetonuria.
  • Failure to link acetonuria to a primary diagnosis.
  • Misinterpretation of laboratory results leading to incorrect coding.
  • Lack of clarity in the clinical notes regarding the patient's metabolic status.
