  • Abnormal Doppler findings

Code-Specific Risks

  • Incorrectly using for size-date discrepancies without confirmed FGR

Coding Notes

  • Ensure documentation includes specific percentile rankings and Doppler findings.

Ancillary Codes

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

Weeks of gestation

Z3A.XX
Used to specify the gestational age.

Differential Codes

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Fetal Growth Restriction to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code O36.5910.

Impact

Clinical: May lead to misdiagnosis or inappropriate management., Regulatory: Increases risk of audit failures., Financial: Potential for denied claims due to insufficient documentation.

Mitigation Strategy

Ensure all ultrasound reports include percentile rankings.

Impact

Reimbursement: Incorrect coding can lead to denied claims., Compliance: May result in audit flags for incorrect coding., Data Quality: Affects the accuracy of clinical data reporting.

Mitigation Strategy

Ensure FGR is confirmed with clinical evidence before using O36.59- codes.

Impact

Lack of specific clinical evidence for FGR coding.

Mitigation Strategy

Ensure all documentation includes specific percentile and Doppler findings.

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.

Documentation Templates for Fetal Growth Restriction

Use these documentation templates to ensure complete and accurate documentation for Fetal Growth Restriction. These templates include all required elements for proper coding and billing.

FGR with abnormal Doppler findings

Specialty: Obstetrics

Required Elements

  • Gestational age
  • Ultrasound findings
  • Doppler results
  • Management plan

Example Documentation

Gestational age: 32 weeks by LMP. Ultrasound findings: EFW <3rd percentile, abnormal umbilical artery Doppler. Management plan: Weekly BPP and Doppler surveillance.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Baby measuring small.
Good Documentation Example
EFW at 5th percentile with reversed end-diastolic flow in umbilical artery, consistent with severe FGR.
Explanation
The good example provides specific measurements and clinical findings supporting FGR.
