Primary ICD-10-CM Code for acute on chronic hfpef

Acute on chronic diastolic (congestive) heart failure
Billable Code

Decision Criteria

clinical Criteria

  • Documented EF ≥50% with acute decompensation signs

documentation Criteria

  • Explicit mention of 'acute on chronic diastolic heart failure'

Applicable To

  • Acute exacerbation of chronic diastolic heart failure
  • Decompensated diastolic heart failure

Excludes

  • Systolic heart failure (I50.2-)
  • Combined systolic and diastolic heart failure (I50.4-)

Clinical Validation Requirements

  • BNP >400 pg/mL indicating acute decompensation
  • Echocardiogram showing EF ≥50%
  • Chest X-ray with vascular congestion

Code-Specific Risks

  • Incorrectly coding as unspecified heart failure
  • Missing documentation of EF or acute/chronic status

Coding Notes

  • Ensure documentation specifies 'acute on chronic' and includes EF and clinical findings.

Ancillary Codes

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

Fluid overload

E87.70
Use when there is documented evidence of fluid overload.

Differential Codes

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

Unspecified diastolic (congestive) heart failure

I50.30
Use I50.30 when the type of heart failure is not specified as acute or chronic.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Acute on Chronic HFpEF to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I50.33.

Impact

Clinical: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims or reduced reimbursement.

Mitigation Strategy

Ensure EF is measured and documented within 24 months., Include EF in all heart failure assessments.

Impact

Reimbursement: May lead to lower DRG assignment and reduced reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data affecting patient care and outcomes.

Mitigation Strategy

Query the provider for clarification on acuity and type of heart failure.

Impact

Inadequate documentation of heart failure type and acuity.

Mitigation Strategy

Implement standardized templates for heart failure documentation.

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.

Hospital Admission for Acute on Chronic HFpEF

Specialty: Cardiology

Required Elements

  • Ejection fraction measurement
  • BNP levels
  • Clinical signs of decompensation

Example Documentation

Assessment: Acute on chronic diastolic HF (I50.33) with EF 58%, acute decompensation due to pneumonia, volume status: 8 lb weight gain, JVD 8cm.

Examples: Poor vs. Good Documentation

Poor Documentation Example
CHF exacerbation, continue diuretics.
Good Documentation Example
Acute on chronic diastolic HF (EF 60%) with decompensation due to dietary noncompliance, evidenced by 5kg weight gain, bilateral crackles.
Explanation
The good example specifies the type and acuity of heart failure and provides clinical evidence.
