Compare key differences between these codes to ensure accurate selection
| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| R73.01 | Impaired fasting glucose | Use when fasting glucose levels are consistently between 100-125 mg/dL without diabetes diagnosis. |
|
| R73.02 | Impaired glucose tolerance | Use when OGTT results indicate impaired glucose tolerance without diabetes. |
|
| R73.03 | Prediabetes | Use when HbA1c indicates prediabetes without diabetes. |
|

Documentation & Coding Risks
Avoid these common issues when documenting Glucose Intolerance.
Using R73.03 without HbA1c documentation
Impact
Clinical: Leads to inaccurate diagnosis records., Regulatory: May result in audit issues., Financial: Affects reimbursement accuracy.
Mitigation
Ensure HbA1c results are documented before coding.
Confusing prediabetes with diabetes
Impact
Reimbursement: Incorrect coding may lead to improper reimbursement rates., Compliance: Misclassification can result in compliance issues., Data Quality: Affects the accuracy of patient health records.
Mitigation
Ensure HbA1c and glucose levels are documented to differentiate between prediabetes and diabetes.
Documentation of glucose levels
Impact
Inadequate documentation can lead to audit discrepancies.
Mitigation
Ensure all glucose test results are clearly documented.
