Related ICD-10 Code Ranges

Complete code families applicable to Cardiac Defibrillator

Z95.810Primary Range

Presence of automatic (implantable) cardiac defibrillator

This code indicates the presence of an implanted cardiac defibrillator and is used as an ancillary code to support the primary diagnosis.

Heart failure and complications

These codes are often used in conjunction with Z95.810 to indicate the underlying condition necessitating the defibrillator.

Decision Criteria

clinical Criteria

  • Presence of an ICD device confirmed by medical records

Applicable To

  • Implanted defibrillator

Excludes

Clinical Validation Requirements

  • Documentation of the presence of an ICD device

Code-Specific Risks

  • Cannot be used as a principal diagnosis

Coding Notes

  • Ensure the primary condition necessitating the ICD is documented.

Ancillary Codes

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

Heart failure, unspecified

I50.9
Use to indicate heart failure as a comorbidity with Z95.810.

Differential Codes

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

Presence of cardiac pacemaker

Z95.0
Use Z95.0 for pacemakers, not defibrillators.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Cardiac Defibrillator to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Z95.810.

Impact

Clinical: May lead to inappropriate ICD use., Regulatory: Non-compliance with CMS guidelines., Financial: Potential claim denials.

Mitigation Strategy

Ensure LVEF is documented in all ICD implantation cases.

Impact

Reimbursement: Incorrect sequencing can lead to claim denials., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate representation of patient condition.

Mitigation Strategy

Always pair with a primary diagnosis code indicating the underlying condition.

Impact

Incomplete documentation of ICD indications and outcomes.

Mitigation Strategy

Implement a standardized documentation template.

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.

ICD Implantation

Specialty: Cardiology

Required Elements

  • Device type
  • Indication for implantation
  • LVEF documentation
  • Lead positions
  • DFT results

Example Documentation

Inserted Medtronic Evera XT DR ICD via left subclavian access. RV lead positioned at apex (threshold 0.7V @ 0.4ms). DFT testing induced VF at 18J, successfully defibrillated at 24J. LVEF 28% by TTE 3/1/25 (I50.21). Meets CMS criteria for primary prevention (I25.5).

Examples: Poor vs. Good Documentation

Poor Documentation Example
ICD placed for heart failure.
Good Documentation Example
CRT-D implanted for primary prevention in ischemic cardiomyopathy (I25.5), LVEF 28% by TTE 3/15/25, NYHA Class III.
Explanation
The good example provides specific clinical details and justification for the ICD implantation.
