| 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. |
|
| R73.09 | Other abnormal glucose | Use when glucose levels are abnormal but do not meet specific criteria for other codes. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Primary ICD-10-CM Codes for glucose intolerance
Decision Criteria
clinical Criteria
- Fasting glucose levels between 100-125 mg/dL
Applicable To
- Fasting plasma glucose 100-125 mg/dL
Excludes
- Diabetes mellitus (E08-E13)
Clinical Validation Requirements
- Two consecutive fasting glucose results between 100-125 mg/dL
Code-Specific Risks
- Misclassification as diabetes if glucose levels exceed 125 mg/dL.
Coding Notes
- Ensure documentation specifies fasting glucose levels and absence of diabetes.
R73.02 - Impaired glucose tolerance
Use when OGTT results indicate impaired glucose tolerance without diabetes.
Applicable To
- 2-hour OGTT result 140-199 mg/dL
Excludes
- Diabetes mellitus (E08-E13)
Clinical Validation Requirements
- 2-hour OGTT result between 140-199 mg/dL
Coding Notes
Document OGTT results clearly to avoid misclassification.
R73.03 - Prediabetes
Use when HbA1c indicates prediabetes without diabetes.
Applicable To
- HbA1c 5.7–6.4%
Excludes
- Diabetes mellitus (E08-E13)
Clinical Validation Requirements
- HbA1c between 5.7% and 6.4%
Coding Notes
Ensure HbA1c results are documented to support prediabetes diagnosis.
R73.09 - Other abnormal glucose
Use when glucose levels are abnormal but do not meet specific criteria for other codes.
Applicable To
- Abnormal glucose levels not meeting criteria for IFG or IGT
Excludes
- Diabetes mellitus (E08-E13)
Clinical Validation Requirements
- Abnormal glucose levels without specific criteria for IFG or IGT
Coding Notes
Document specific glucose test results to justify use of this code.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Glucose Intolerance to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R73.01.
Impact
Clinical: Leads to inaccurate diagnosis records., Regulatory: May result in audit issues., Financial: Affects reimbursement accuracy.
Mitigation Strategy
Ensure HbA1c results are documented before coding.
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 Strategy
Ensure HbA1c and glucose levels are documented to differentiate between prediabetes and diabetes.
Impact
Inadequate documentation can lead to audit discrepancies.
Mitigation Strategy
Ensure all glucose test results are clearly documented.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
