Decision Criteria
clinical Criteria
- Presence of guttae and low endothelial cell count
Clinical Validation Requirements
- Specular microscopy showing guttae
- Endothelial cell count < 1,000 cells/mm²
Code-Specific Risks
- Incorrect laterality documentation
Coding Notes
- Ensure laterality is documented to avoid unspecified codes.

Use when endothelial corneal dystrophy is diagnosed in the left eye.
Applicable To
- Fuchs' dystrophy, left eye
Excludes
- Bullous keratopathy (H18.10-H18.13)
Clinical Validation Requirements
- Specular microscopy showing guttae
- Endothelial cell count < 1,000 cells/mm²
Coding Notes
Ensure laterality is documented to avoid unspecified codes.
H18.513 - Endothelial corneal dystrophy, bilateral
Use when endothelial corneal dystrophy is diagnosed in both eyes.
Applicable To
- Fuchs' dystrophy, bilateral
Excludes
- Bullous keratopathy (H18.10-H18.13)
Clinical Validation Requirements
- Specular microscopy showing guttae
- Endothelial cell count < 1,000 cells/mm²
Coding Notes
Ensure laterality is documented to avoid unspecified codes.
H18.519 - Endothelial corneal dystrophy, unspecified eye
Use only when laterality is not documented.
Applicable To
- Fuchs' dystrophy, unspecified eye
Excludes
- Bullous keratopathy (H18.10-H18.13)
Clinical Validation Requirements
- Specular microscopy showing guttae
- Endothelial cell count < 1,000 cells/mm²
Coding Notes
Avoid using unspecified codes when laterality is known.

H18.10Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Endothelial Corneal Dystrophy to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code H18.511.
Impact
Clinical: May lead to incorrect treatment planning., Regulatory: Non-compliance with ICD-10 coding guidelines., Financial: Potential for claim denials.
Mitigation Strategy
Implement checklist for documentation review., Educate staff on importance of laterality.
Impact
Reimbursement: May lead to claim denials or reduced reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Ensure documentation specifies laterality and use the appropriate code.
Impact
Failure to document laterality can lead to audit findings.
Mitigation Strategy
Implement documentation audits to ensure laterality is recorded.
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.
