Other abnormal glucose

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 R73.09 is a billable code used to indicate a diagnosis of other abnormal glucose.

Key Diagnostic Point:

R73.09 is used to classify abnormal glucose levels that do not fit into more specific categories of glucose abnormalities, such as diabetes mellitus or impaired glucose tolerance. This code encompasses a range of clinical scenarios where glucose levels are outside the normal range but do not meet the criteria for established conditions. Common laboratory findings may include elevated fasting glucose levels, abnormal glucose tolerance test results, or random glucose levels that are inconsistent with normal physiological ranges. Symptoms may vary widely and can include fatigue, increased thirst, frequent urination, or no symptoms at all. The clinical context for this code often involves patients undergoing routine screening for diabetes or those presenting with nonspecific symptoms that warrant further investigation into their glucose metabolism. It is essential for healthcare providers to document the clinical rationale for testing and the specific findings that led to the use of this code to ensure accurate coding and billing.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of potential underlying causes for abnormal glucose levels
  • Need for comprehensive documentation to support the diagnosis
  • Differentiation from other glucose-related codes
  • Potential overlap with other metabolic disorders

Audit Risk Factors

  • Inadequate documentation of clinical findings
  • Failure to specify the reason for abnormal glucose testing
  • Misuse of the code when a more specific diagnosis exists
  • Inconsistent lab results not supported by clinical symptoms

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Documentation should include the patient's clinical history, symptoms, and rationale for glucose testing. Any comorbid conditions should also be noted.

Common Clinical Scenarios

Patients presenting with fatigue, polyuria, or routine screening results showing abnormal glucose levels.

Billing Considerations

Consideration of the patient's overall metabolic health and any medications that may affect glucose levels.

Emergency Medicine

Documentation Requirements

Acute care documentation must include immediate clinical findings, lab results, and any interventions performed.

Common Clinical Scenarios

Patients presenting with acute symptoms such as altered mental status or dehydration due to hyperglycemia.

Billing Considerations

Rapid assessment and documentation of glucose levels are critical in emergency settings to guide treatment.

Coding Guidelines

Use R73.09 When
  • According to ICD
  • 10 coding guidelines, R73
  • 09 should be used when abnormal glucose levels are documented without a more specific diagnosis
  • Coders must ensure that the clinical documentation supports the use of this code and that it is not used inappropriately when a more specific diagnosis is available
