| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| H18.611 | Keratoconus, stable, right eye | Use when keratoconus is stable in the right eye with documented stability over time. |
|
| H18.621 | Keratoconus, unstable, right eye | Use when keratoconus is unstable in the right eye with documented rapid progression. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

H18.621 - Keratoconus, unstable, right eye
Use when keratoconus is unstable in the right eye with documented rapid progression.
Applicable To
- Unstable keratoconus affecting the right eye
Excludes
- Stable keratoconus (H18.611)
Clinical Validation Requirements
- Recent hydrops or rapid progression (>2D steepening in 6 months)
Coding Notes
Ensure documentation supports the instability of keratoconus.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Keratoconus to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code H18.611.
Impact
Clinical: Inadequate assessment of disease progression., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials due to lack of supporting evidence.
Mitigation Strategy
Ensure all corneal measurements are documented in the patient's record., Regularly update documentation with new test results.
Impact
Reimbursement: Unspecified codes may lead to claim denials., Compliance: Non-compliance with specificity requirements., Data Quality: Decreased accuracy in health records.
Mitigation Strategy
Always specify laterality and stability to avoid unspecified codes.
Impact
Risk of using unspecified codes leading to audits.
Mitigation Strategy
Always document laterality and stability to use specific codes.
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.
