Applicable To
- Elevated glucose challenge test without diabetes diagnosis
Excludes
- Diabetes mellitus (E08-E13)
Clinical Validation Requirements

Code-Specific Risks
- Confusion with diabetes codes if GDM is not confirmed
Coding Notes
- Ensure documentation specifies the GCT value and context (e.g., pregnancy).
O24.4- - Gestational diabetes mellitus
Use when gestational diabetes is confirmed following an elevated GCT.
Applicable To
- Gestational diabetes diagnosed after GCT and GTT
Excludes
- Pre-existing diabetes (E08-E13)
Clinical Validation Requirements
- GTT confirms gestational diabetes
Coding Notes
Ensure GTT results are documented to support the diagnosis.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Elevated Glucose Challenge Test to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R73.0.
Impact
Clinical: May lead to inappropriate follow-up care., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials due to insufficient documentation.
Mitigation Strategy
Ensure GCT values are recorded in all relevant patient encounters., Train staff on the importance of documenting test results.
Impact
Reimbursement: Incorrect coding can lead to claim denials., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data on diabetes prevalence.
Mitigation Strategy
Use R73.0 until GTT confirms diabetes.
Impact
Using diabetes codes without confirmation can trigger audits.
Mitigation Strategy
Ensure GCT and GTT results are documented and codes are selected based on confirmed diagnoses.
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.
