Impaired fasting glucose

BILLABLE STATUSYes

Code Description

ICD-10 R73.01 is a billable code used to indicate a diagnosis of impaired fasting glucose.

Key Diagnostic Point:

Impaired fasting glucose (IFG) is a metabolic condition characterized by elevated blood glucose levels after an overnight fast, specifically defined as a fasting plasma glucose level of 100 to 125 mg/dL (5.6 to 6.9 mmol/L). This condition is often a precursor to type 2 diabetes and is associated with insulin resistance. Patients with IFG may not exhibit overt symptoms; however, they may experience signs of metabolic syndrome, such as obesity, hypertension, and dyslipidemia. Laboratory findings typically include abnormal glucose tolerance tests and elevated HbA1c levels. IFG is significant as it indicates an increased risk for developing diabetes and cardiovascular diseases. Regular monitoring and lifestyle modifications, including diet and exercise, are crucial for managing this condition and preventing progression to diabetes.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in laboratory reference ranges
  • Overlap with other glucose-related codes
  • Need for precise documentation of fasting status
  • Potential for misclassification with diabetes codes

Audit Risk Factors

  • Inadequate documentation of fasting status
  • Misinterpretation of lab results
  • Failure to document associated conditions
  • Inconsistent use of codes for glucose abnormalities

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Detailed patient history, fasting status, and lab results must be documented.

Common Clinical Scenarios

Routine screening for diabetes in at-risk populations, management of metabolic syndrome.

Billing Considerations

Consider documenting lifestyle factors and comorbidities that may influence glucose levels.

Emergency Medicine

Documentation Requirements

Acute care documentation should include glucose levels and any immediate interventions.

Common Clinical Scenarios

Patients presenting with symptoms of hyperglycemia or metabolic derangements.

Billing Considerations

Ensure clarity on whether the glucose measurement was taken in a fasting state.

Coding Guidelines

Inclusion Criteria

Use R73.01 When
  • According to ICD
  • 10 guidelines, R73
  • 01 should be used when the patient has documented impaired fasting glucose levels without a diagnosis of diabetes
  • Ensure that the fasting status is clearly documented in the medical record
