CodeDescriptionWhen to UseKey Documentation
O35.8XXMaternal care for other (suspected) fetal abnormality and damageUse during prenatal care when fetal pyelectasis is suspected based on ultrasound findings.
  • Ultrasound measurement of anteroposterior renal pelvic diameter (APRPD) ≥4 mm before 20 weeks gestation.
Q62.0Congenital hydronephrosisUse postnatally when hydronephrosis is confirmed.
  • Postnatal ultrasound confirming hydronephrosis.

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

clinical Criteria

  • APRPD measurement ≥4 mm before 20 weeks gestation.

Applicable To

  • Suspected fetal renal anomaly

Excludes

  • Confirmed postnatal hydronephrosis (Q62.0)

Clinical Validation Requirements

  • Ultrasound measurement of anteroposterior renal pelvic diameter (APRPD) ≥4 mm before 20 weeks gestation.

Code-Specific Risks

  • Incorrectly using postnatal codes during prenatal period.

Coding Notes

  • Ensure documentation includes specific measurements and laterality.

Ancillary Codes

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

Encounter for other screening for genetic and chromosomal anomalies

Z13.79
Use when genetic counseling or screening is performed.

Differential Codes

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

Maternal care for (suspected) chromosomal abnormality in fetus

O35.1XX
Use when chromosomal abnormalities are suspected or confirmed.

Obstructive and reflux uropathy

N13.3
Use when obstruction or reflux is identified.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Fetal Pyelectasis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code O35.8XX.

Impact

Clinical: Inadequate clinical information for follow-up., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims due to insufficient documentation.

Mitigation Strategy

Always include laterality in ultrasound reports., Use standardized templates for documentation.

Impact

Reimbursement: Incorrect DRG assignment leading to lower reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation Strategy

Use O35.8XX during prenatal care.

Impact

Using postnatal codes during prenatal care.

Mitigation Strategy

Regular training on code sequencing and documentation requirements.

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.

Frequently Asked Questions

Common questions about ICD-10 coding for Fetal Pyelectasis, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for Fetal Pyelectasis

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

Prenatal ultrasound finding of pyelectasis

Specialty: Obstetrics

Required Elements

  • Gestational age
  • APRPD measurement
  • Laterality
  • Associated findings

Example Documentation

24w1d gestation with isolated fetal pyelectasis: Right APRPD: 6.8 mm, Left APRPD: 5.1 mm, No caliectasis.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Mild fetal kidney dilation noted.
Good Documentation Example
Left renal pelvis measures 6.2 mm APRPD at 22w3d, no calyceal dilatation.
Explanation
The good example provides specific measurement, gestational age, and absence of calyceal dilatation, which are essential for accurate coding.
