Essential facts and insights about Hypoplastic Right Heart Syndrome

Hypoplastic Right Heart Syndrome is coded as Q22.6 in ICD-10. Ensure detailed anatomical documentation for accurate coding.

Primary ICD-10-CM Code for syndrome

Hypoplastic Right Heart Syndrome
Billable Code

Decision Criteria

clinical Criteria

  • Echocardiogram confirms hypoplastic right ventricle and pulmonary atresia.

documentation Criteria

  • Detailed anatomical description including associated defects.

Applicable To

  • Hypoplastic right ventricle
  • Pulmonary atresia

Excludes

  • Tricuspid atresia (Q22.4)
  • Pulmonary atresia with intact ventricular septum (Q22.0)

Clinical Validation Requirements

  • Echocardiogram showing hypoplastic right ventricle
  • Documented pulmonary atresia or stenosis

Code-Specific Risks

  • Misclassification with other congenital heart defects
  • Failure to document anatomical specifics

Coding Notes

  • Ensure detailed anatomical documentation to support HRHS coding.

Ancillary Codes

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

Cyanosis

R23.0
Use when cyanosis is present as a symptom of HRHS.

Heart failure, unspecified

I50.9
Use when heart failure is a manifestation of HRHS.

Differential Codes

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

Tricuspid atresia

Q22.4
Absence of tricuspid valve vs. hypoplastic right ventricle.

Pulmonary atresia with intact ventricular septum

Q22.0
Presence of intact ventricular septum vs. VSD.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Hypoplastic Right Heart Syndrome to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Q22.6.

Impact

Clinical: Incomplete clinical picture affecting treatment planning., Regulatory: Potential non-compliance with coding standards., Financial: Risk of claim denials due to insufficient documentation.

Mitigation Strategy

Use structured templates, Regular training on documentation standards

Impact

Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate clinical data affecting patient records.

Mitigation Strategy

Use I27.0 for acquired conditions.

Impact

Lack of detailed anatomical documentation can lead to audit flags.

Mitigation Strategy

Implement mandatory echocardiogram reporting in patient records.

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 Hypoplastic Right Heart Syndrome

Use these documentation templates to ensure complete and accurate documentation for Hypoplastic Right Heart Syndrome. These templates include all required elements for proper coding and billing.

Newborn with HRHS

Specialty: Pediatric Cardiology

Required Elements

  • Anatomical description
  • Echocardiogram findings
  • Hemodynamic status

Example Documentation

Diagnosis: Hypoplastic Right Heart Syndrome (Q22.6). Anatomy: Hypoplastic RV, pulmonary atresia, 3mm ASD. Hemodynamics: Duct-dependent circulation.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Cardiac anomaly noted.
Good Documentation Example
Severe RV hypoplasia (Z-score -4.2), pulmonary atresia, 3.5mm ASD, duct-dependent flow (SpO2 78% pre-ductal).
Explanation
The good example provides specific anatomical and hemodynamic details necessary for accurate coding.
