CodeDescriptionWhen to UseKey Documentation
O24.410Gestational diabetes mellitus in pregnancy, unspecified controlUse when gestational diabetes is diagnosed but control method is not specified.
  • Diagnosis of gestational diabetes without specified control method
O24.414Gestational diabetes mellitus in pregnancy, insulin controlledUse when gestational diabetes is controlled by insulin.
  • Diagnosis of gestational diabetes with insulin as the control method

Clinical Decision Support

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

Decision Criteria

documentation Criteria

  • Control method not documented

Applicable To

  • Gestational diabetes mellitus in pregnancy, unspecified control

Excludes

  • Pre-existing diabetes mellitus (E08-E13)

Clinical Validation Requirements

  • Diagnosis of gestational diabetes without specified control method

Code-Specific Risks

  • Increased audit risk due to lack of specificity

Coding Notes

  • Ensure documentation specifies the control method to avoid using unspecified codes.

Ancillary Codes

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

Weeks of gestation of pregnancy, unspecified

Z3A.00
Use to specify gestational age when exact weeks are not documented.

28 weeks gestation of pregnancy

Z3A.28
Use to specify the gestational age at 28 weeks.

Differential Codes

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

Abnormal glucose tolerance in pregnancy

O99.81
Use for abnormal glucose tolerance without meeting gestational diabetes criteria.

Pre-existing type 2 diabetes mellitus, in pregnancy

O24.11
Use for patients with pre-existing type 2 diabetes diagnosed before pregnancy.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Gestational Diabetes to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code O24.410.

Impact

Clinical: Inadequate treatment planning, Regulatory: Increased audit risk, Financial: Potential claim denials

Mitigation Strategy

Use templates to ensure all elements are documented., Regular training on documentation standards.

Impact

Reimbursement: May lead to claim denials or payment delays., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate representation of patient condition.

Mitigation Strategy

Do not use Z79.4 as insulin control is specified within O24.4 codes.

Impact

Using O24.410 without specifying control method increases audit risk.

Mitigation Strategy

Ensure documentation includes specific control method.

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.

Example Documentation

Gestational Diabetes Management - Diagnosis Date: 01/15/2023, Control Method: Insulin, OGTT Results: Fasting 98 mg/dL, 1-hr 195 mg/dL, 2-hr 165 mg/dL, 3-hr 145 mg/dL, Complications: None, Gestational Age: 28 weeks (Z3A.28)

Examples: Poor vs. Good Documentation

Poor Documentation Example
GDM diagnosed. Follow-up scheduled.
Good Documentation Example
GDM diagnosed at 27+3 weeks via 3-hr OGTT (fasting 97, 1-hr 190, 2-hr 160, 3-hr 142). Started on insulin lispro 8 units nightly. No macrosomia on US.
