Decision Criteria

clinical Criteria

  • Fasting glucose between 100-125 mg/dL

documentation Criteria

  • Explicit documentation of fasting glucose levels

Applicable To

  • Fasting glucose 100-125 mg/dL

Excludes

  • Diabetes mellitus (E11.9)

Clinical Validation Requirements

  • Fasting glucose between 100-125 mg/dL
  • No diagnosis of diabetes

Code-Specific Risks

  • Ensure documentation specifies fasting glucose levels and absence of diabetes diagnosis.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Obesity

E66.9
Use when BMI is ≥30 and contributes to impaired fasting glucose.

Hypertension

I10
Use when hypertension is present alongside impaired fasting glucose.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Impaired glucose tolerance

Use R73.02 for OGTT results between 140-199 mg/dL.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Impaired Fasting Glycaemia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R73.01.

Impact

Clinical: Inaccurate diagnosis and treatment, Regulatory: Potential audit issues, Financial: Claim denials

Mitigation Strategy

Use specific lab values, Avoid terms like 'borderline glucose'

Impact

Reimbursement: Incorrect DRG assignment may affect reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate patient records.

Mitigation Strategy

Ensure fasting glucose is documented and diabetes is ruled out.

Impact

Lack of specific glucose values can trigger audits.

Mitigation Strategy

Ensure all lab results are documented with dates.

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.
