Primary ICD-10-CM Code for .219
Decision Criteria
clinical Criteria
- Presence of acute symptoms and elevated IOP with unspecified laterality
documentation Criteria
- Lack of specified laterality in the medical record
Applicable To
- Acute angle-closure glaucoma attack
- Acute angle-closure crisis
Excludes
- Malignant glaucoma (H40.83-)
Clinical Validation Requirements
- Sudden onset of symptoms such as eye pain, nausea, blurred vision
- Intraocular pressure (IOP) >30 mmHg
- Gonioscopy showing closed angles
Code-Specific Risks
- Potential for audit if used excessively without specifying laterality
- May affect reimbursement if specificity is required by payer
Coding Notes
- Ensure documentation specifies 'acute' and 'angle-closure' to avoid confusion with chronic glaucoma codes.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Z79.3Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Acute Angle-Closure Glaucoma to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code H40.219.
Impact
Clinical: May lead to inappropriate treatment planning, Regulatory: Non-compliance with coding standards, Financial: Potential for denied claims due to lack of specificity
Mitigation Strategy
Always document the affected eye when possible, Query the provider if laterality is unclear
Impact
Reimbursement: Incorrect coding may lead to denied claims, Compliance: Non-compliance with ICD-10 coding guidelines, Data Quality: Inaccurate clinical data reporting
Mitigation Strategy
Use H40.22- for chronic cases
Impact
Frequent use of unspecified codes may trigger audits.
Mitigation Strategy
Ensure documentation is as specific as possible and query providers when necessary.
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.
